- Description: Abstract: Purpose - ‘Technological Intelligence’ is the capacity to appreciate and adapt technological advancements, and ‘Artificial Intelligence’ is the key to achieve persuasive operational transformations in majority of contemporary organizational set-ups. Implicitly, artificial intelligence (the philosophies of machines to think, behave, and perform either same or similar to humans) has knocked the doors of business organizations as an imperative activity. Artificial intelligence, as a discipline, initiated by scientist John McCarthy and formally publicized at Dartmouth Conference in 1956, now occupies a central stage for many organizations. Implementation of artificial intelligence provides competitive edge to an organization with a definite augmentation in its societal and corporate status. Mere application of a concept will not furnish real output until and unless its performance is reviewed systematically. Technological changes are dynamic and advancing at a rapid rate. Subsequently, it becomes highly crucial to understand that where have we reached with respect to artificial intelligence research. Present article aims to review significant work by eminent researchers towards artificial intelligence in the form of top contributing universities, authors, keywords, funding sources, journals, and citation statistics...

- Description: D.Ing. , “Innovation is the act of introducing something new” (Byrd & Brown, 2003). When companies are competing on the technology “playground” they need to be innovative. By analysis according to Byrd & Brown (Byrd & Brown, 2003) the “act of introducing”, relates to risk taking, and the “new” relates to creativity, and therefore these concepts, creativity and risk taking, in combination, are what innovation is all about. Risk management has become one of the greatest challenges of the 21st century, and one of the main components in innovation and the technology driven industry, intensifying the need for a systematic approach to managing uncertainties. During the development and design of complex engineering products, the input and teamwork of multiple participants from various backgrounds are required resulting in complex interactions. Risk interactions exist between the functional and physical elements within such a system and its sub-systems in various dimensions such as spatial interaction, information interaction etc. The relationships are of a multi-dimensional complexity that cannot be simplified using the standard task management tools (Yassine A. A., 2004). To find a meaningful starting point for the seemingly boundless subject of risk management the research takes a step back into the basic definition of risk management and follows an exploratory research methodology to explore each of the risk management processes (risk assessment, risk identification, risk analysis, risk evaluation, risk treatment and risk monitoring and review) and how these processes can be enhanced using the design structure matrix (DSM) and fuzzy logic thinking. The approach to risk management within an organisation should be seen as a holistic approach similar to the total quality management process, providing the ii opportunity to incorporated risk management during the design process as a concurrent task. The risk management model is then developed concurrently (during the design phase) using product development methodologies such as conceptual modeling and prototyping, and ultimately the prototype is tested using a case study. Finally resulting in a clustered DSM providing a visual representation of the system risk areas similar to the methodology used in Finite Element Analysis (FEA). The research combines alternative system representation and analysis techniques (Warfield, 2005), in particular the design structure matrix, and fuzzy logic to quantify the risk management effort neccessary to deal with uncertain and imprecise interactions between system elements.

- Description: M.Sc. (Computer Science) , General machine intelligence represents the principal ambition of artificial intelligence research: creating machines that readily adapt to their environment. Machine learning represents the driving force of adaptation in artificial intelligence. However, two pertinent dilemmas emerge from research into machine learning. Firstly, how do intelligent agents learn effectively in real-world environments, in which randomness, perceptual aliasing and dynamics complicate learning algorithms? Secondly, how can intelligent agents exchange knowledge and learn from one another without introducing mathematical anomalies that might impede on the effectiveness of the applied learning algorithms? In a robotic search and rescue scenario, for example, the control system of each robot must learn from its surroundings in a fast-changing and unpredictable environment while at the same time sharing its learned information with others. In well-understood problems, an intelligent agent that is capable of solving task-specific problems will suffice. The challenge behind complex environments comes from fact that agents must solve arbitrary problems (Kaelbling et al. 1996; Ryan 2008). General problem-solving abilities are hence necessary for intelligent agents in complex environments, such as robotic applications. Although specialized machine learning techniques and cognitive hierarchical planning and learning may be a suitable solution for general problem-solving, such techniques have not been extensively explored in the context of cooperative multi-agent learning. In particular, to the knowledge of the author, no cognitive architecture has been designed which can support knowledge-sharing or self-organisation in cooperative multi-agent learning systems. It is therefore social learning in real-world applications that forms the basis of the research presented in this dissertation. This research aims to develop a distributed cognitive architecture for cooperative multi-agent learning in complex environments. The proposed Multi-agent Learning through Distributed Adaptive Contextualization Distributed Cognitive Architecture for Multi-agent Learning (MALDAC) Architecture comprises a self-organising multi-agent system to address the communication constraints that the physical hardware imposes on the system. The individual agents of the system implement their own cognitive learning architecture. The proposed Context-based Adaptive Empathy-deliberation Agent (CAEDA) Architecture investigates the applicability of emotion, ‘consciousness’, embodiment and sociability in cognitive architecture design. Cloud computing is proposed as a method of service delivery for the learning system, in which the MALDAC Architecture governs multiple CAEDA-based agents. An implementation of the proposed architecture is applied to a simulated multi-robot system to best emulate real-world complexities. Analyses indicate favourable results for the cooperative learning capabilities of the proposed MALDAC and CAEDA architectures.

- Description: M.Sc. (Computer Science) , Corporations throughout the world are facing numerous challenges in today’s competitive marketplace and are continuously looking for new and innovative means and methods of gaining competitive advantage. One of the means used to gain this advantage is that of information technology, and all the associated technologies and principles. These are primarily used to facilitate business processes and procedures that are designed to provide this competitive advantage. Significant attention has been given to each of the individual technologies and principles of Artificial Intelligence, Knowledge Management, Information Security, and Intranets and how they can be leveraged in order to improve efficiency and functionality within a corporation. However, in order to truly reap the benefits of these technologies and principles, it is necessary to look at them as a collaborative system, rather as individual components. This dissertation therefore investigates each of these individual technologies and principles in isolation, as well as in combination with each other to outline potential advantages, associated risks, and disadvantages when combining them within the corporate world. Based on these, the Intelligently Generated Knowledge (IGK) framework is outlined to implement such a collaborative system. Thereafter, an investigation of a theoretical situation is conducted based on this framework to examine the impact of the implementation of this type of collaborative system. The potential increase in cost savings, efficiency and functionality of corporations that would employ the IGK framework is clearly outlined in the theoretical example, and should this approach be adopted, it would be able to provide significant competitive advantage for any corporation.

- Description: Researchers in artificial intelligence and agent technologies are presented with a massive array of various technologies that they might use for their research projects. It is difficult for researchers to test their theories effectively in the field. It takes a great deal of time to develop the platform on which the newly created agent will be tested, with little or no time left for troubleshooting and the investigation of further solutions. Every time a new technique or agent is researched, the agent has to be redeveloped from the ground up. This makes it difficult for researchers to compare their own theories with previously developed components. With the wide range of technologies and techniques available, there is no easy way to effectively make use of the various components, as each tool uses different technologies that cannot be combined easily. This dissertation outlines the new plug-in oriented agent architecture (POAA) and describes the agents that use the POAA. POAA agents make extensive use of functional and controller-based plug-ins in order to extend the functionality and behaviour of the agent. The architecture was designed to facilitate machine learning and agent mobility techniques. POAA agents are created by mounting newly created dynamic plug-in components into the static structure of the agent. The static structure of the agent serves as the basis of agent functionality and as the controller for the agent’s life cycle. The static and dynamic components of the POAA agent interact with each other in order to perform the agent’s required tasks. The use of plug-ins will greatly improve the effectiveness of researchers, as only a single, standard architecture will exist. Researchers only need design and develop the plug-in required for their specific agent to function as desired. This will also facilitate the comparison of various tools and methods, as only the components being reviewed need to be interchanged to measure system performance. The use of different plug-in architectures is also investigated. This includes deciding if the plug-in base will be configured at application run-time or at the time of application compilation. This dissertation focuses on techniques that will facilitate machine learning and agent mobility. For these purposes, extensive use is made of the machine learning tool WEKA developed by University of Waikato in New Zealand [Wi00]. The use of Java in the prototype will also facilitate the cross platform capability of the proposed agents. , Prof. E.M. Ehlers

- Description: Abstract: Autonomous vehicles, also known as self-driving cars, refer to vehicles that can travel on public roads to destinations with minimal to no interaction with human beings. These types of cars can respond to traffic-related incidents faster and more precisely than human beings, thus potentially reducing the number of traffic accidents, subsequent pedestrian injuries and even fatalities. Autonomous vehicles have been a major focus of artificial intelligence research over the past few years, with major developments being contributed to the industry by Google, Bosch, and leading companies in the automobile industry. The study presented in the dissertation explores the use of Intelligent Agents as a computer science abstraction that encapsulates the several components of an autonomous vehicle, in order to promote component modularity and to allow the inclusion of newer technologies that could further improve the effectiveness of autonomous vehicles. A particular recent advancement in the field of autonomous vehicles is the use of intervehicle communications, which supplements the array of sensors provided in the vehicles, in case of failure or inability to produce sufficient data that would be necessary for the vehicle to make a decision. The agent model proposed in the dissertation places a paramount importance on the communications mechanism, incorporating it in its agent architecture, in order to produce an autonomous vehicle model that is safer and more effective than current solutions. The autonomous vehicle agent model, given research constraints, was deployed in a simulated 3D urban traffic environment, where it was tested in a number of scenarios where a vehicle's sensors failed or provided insufficient data, preventing a safe journey for the vehicle's passengers, passengers of other vehicles and pedestrians in the simulated environment. The results of the tests demonstrated that an inter-vehicle communications mechanism, even with limited transmission range, effectively complements the existing modules of an autonomous vehicle, and is especially useful in case one of the modules fails. , M.Sc.

- Description: Abstract: Current situation in business, economies and the world indicate that artificial intelligence (AI), the Internet of Things (IoT) and robotics are some of the technologies that is and will continue to have a tremendous impact on businesses, economies and everyday human life. These technologies amongst others are reshaping the global landscape and business ecosystems and the manner in which business is conducted in the fourth industrial revolution (4IR). Generic commercialisation lifecycles and business models require adaptation in the 4IR, which will aid successful business for a knowledge management (KM) consulting firm. The study focussed on conceptualising and developing a commercialisation lifecycle (CLC) for a KM consulting firm in the 4IR. The research objective was to conceptualise a business model canvas (BMC) and develop an IKM framework that can be used specifically by a KM consulting firm, including entrepreneurs, small businesses and professional business consulting firms in the 4IR. Literature shows that commercialisation lifecycles and business models need to change continuously, especially on the front of the 4IR. To remain competitive and sustain a healthy business, KM consulting firms will need to upskill and improve current business operations. Upskilling, changing and preparing for the 4IR, give competitive advantage over competitors. New technologies need to be embraced and harnessed to exploit the innovative capabilities and value add new technologies offer. With an improved, adapted and updated CLC and BMC in place, a KM consulting firm will be able to provide innovative services to clients, ensuring profitability. The research methodology for the study was qualitative in nature, with an inductive and exploratory approach. Grounded in the interpretivist paradigm, the inductive approach allowed the study to explore a specific phenomenon and identify themes in order to explain patterns. A conceptual framework was developed, using existing literature, to conceptualise a CLC for a KM consulting firm in the 4IR. Data was collected through content analysis and in-depth faceto- face interviews, through multi-method qualitative research. Purposive sampling was selected to determine the 4 participants for the interviews, through critical case sampling, allowing 3 participants to be interviewed and the fourth participant to be used for testing the findings of the interviews. Interviews and testing of the interviews were transcribed, coded, and categorised through the Data Analysis Spiral. Research findings, through triangulation found that the conceptualisation and development of a CLC is crucial; that the conceptualisation of a BMC is crucial; and that new services and the development of an IKM framework is crucial; which will allow a KM consulting firm, including entrepreneurs, small businesses and professional business consulting firms to be successful in the 4IR.

- Description: D.Phil. , Computer-based information systems will probably always have to contend with security issues. Much research have already gone into the field of information security. These research results have yielded some very sophisticated and effective security mechanisms and procedures.

The characterization of two- and three-dimensional Random Context Grammars by two- and three-dimensional Random Context Automata are investigated. This thesis is an attempt to progressively extend a certain class of grammars to higher dimensions where the class of languages generated in each dimension is contained in the class of languages generated in the next higher dimension. Random Context Array Automata which characterizes Random Context Array Grammars (Von Solms [4,5]) are defined. The power of both Random Context Array Grammars and Random Context Array Automata is inherent in the fact that the replacement of symbols in figures is subject to horizontal, vertical and global context. A proof is given for the equivalence of the class of languages generated by Random Context Array Grammars and the class of languages accepted by Random Context Array Automata. The two-dimensional Random Context Array Grammars are extended to three dimensions. Random Context Structure Grammars generate three-dimensional structures. A characteristic of Random Context Structure Grammars is that the replacement of symbols in a structure is subject to seven relevant contexts.

- Description: Abstract : Intelligent Automation (IA) entails advanced knowledge-based technologies associated with the so-called Fourth Industrial Revolution (4IR). In this study, the phrase “IA journey” refers to the processes of knowledge-based automation and new workforce implementation. The study’s unit of analysis is not as much the IA journey itself, rather it is an analysis of what constitutes a balanced approach to IA implementation and adoption within an organisation. For example, employees’ feelings of uncertainty during an organisation’s IA journey could cause an imbalance in staff morale and resistance from employees to adapt to the changes. Therefore, the main research question of this study is: What are the components of a balanced approach to knowledge-based automation and new workforce implementation of a financial institution? The research question aligns to the world of service delivery that is changing at an alarming rate, with customers expecting fast, personalised, digital service. The landscape for financial institutions is changing, for example, traditional competitors are taking steps to meet customer demands and non-traditional competitors are entering the market place, threatening the existence of traditional financial institutions, commonly referred to as banks. The literature reveals that the evolution of Internet usage and the influence of social media and smart phones have increased the significance of technology and digital service in the financial services industry. Adoptions of these technologies is vital if traditional banks want to remain relevant in the market where financial technologies companies (Fintechs), and small, digitally nimble start-ups can provide the quick, personalised service that customers expect. Already many financial institutions have started to investigate the opportunities that technologies such as IA and chatbots provide. The potential of chatbot technology to improve customer experience and reduce operational costs make it an attractive option for organisations to consider. Literature reveals that the cost of implementation of this technology is a fraction of the cost of legacy system re-writes. The ability of this technology to integrate with existing systems and improve turnaround time and service to customers makes the IA journey a favourable choice. The IA journey of one South African Financial Institution (SAFI) formed the focus of this study. Research was conducted within the SAFI into the application of this technology across the organisation to understand the impact that the changes experienced had on the employees of the organisation. Understanding how these changes impact employees helps in determining the best ways to manage the changes in order to develop a balanced approach to implementation and adaption of IA within an organisation. The empirical study followed a qualitative research design, featuring qualitative data collection and analysis techniques. Secondary data were collected and displayed in order to show case v hoe IA project were implemented into the organisation. The philosophical paradigm that suited a study of this nature was interpretivism as the research was socially constructed in its aim to understand the adoption processes of the organisation implementing an IA programme. The research followed an inductive approach as the study’s conceptual framework was developed based on data collected and conclusions drawn through the analysis of this data. The study involved the collection of data through the use of interviews conducted across junior and senior management levels within the business units impacted by the changes associated with the IA journey. The aim of these interviews was to gain an understanding of employees’ perceptions of the IA journey across the organisation as well as understand the experiences of those involved in the IA programme. Secondary data was also collected from five SAFI use cases, which provided a rich source for quantitative data. The presentation of results regarding the outcomes of use cases implemented across the organisation is in accordance to the University of Johannesburg Code of Academic and Research Ethics. The research findings informed the development of a conceptual framework, which can be used to encourage a balanced approach towards IA implementation and adoption throughout an organisation that is experiencing major changes. This study reveals that employees’ fears of the changes need to be identified and managed early in order to avoid resistance to the changes and negative perceptions of the technology being created. The conceptual framework identifies the components that a financial institution can use in its balanced approach to increase adoption and reduce fears. Moreover, the study revealed the need for organisations to invest in technologies of the future and the benefits that this technology can have for the organisation. Customer experience and expectations form a vital part of any organisation and the lessons learnt in the value this technology can provide in creating a great customer experience are invaluable.

- Description: M.Ing. , A machine vision system must, by definition, be intelligent, adaptable and reliable to satisfY the objectives of a system that is highly interactive with its dynamic environment and therefore prone to outside error factors. A machine vision system is described that utilizes a 2D captured web cam image for the purpose of intelligent object recognition, gripping and handling. The system is designed to be generic in its application and adaptable to various gripper configurations and handling configurations. This is achieved by using highly adaptable and intelligent recognition algorithms the gathers as much information as possible from a 2D colour web cam image. Numerous error-checking abilities are also built into the system to account for possible anomalies in the working environment. The entire system is designed around four separate but tightly integrated systems, namely the Recognition, Gripping and Handling structures and the Component Database which acts as the backbone of the system. The Recognition system provides all the input data that is then used for the Gripping and Handling systems. This integrated system functions as a single unit but a hierarchical structure has been used so that each of the systems can function as a stand-alone unit. The recognition system is generic in its ability to provide information such as recognized object identification, position and other orientation information that could be used by another handling system or gripper configuration. The Gripping system is based on a single custom designed gripper that provides basic gripping functionality. It is powered by a single motor and is highly functional with respect to the large range of object sizes that it can grip. The Handling Sub-system controls gripper positioning and motion. The Handling System incorporates control of the robot and the execution of both predetermined and online adaptable handling algorithms based on component data. It receives data from the Component database. The database allows the transparent ability to add and remove objects for recognition as well as other basic abilities. Experimental verification of the system is performed using a fully integrated and automated program and hardware control system developed for this purpose. The integration of the proposed system into a flexible and reconfigurable manufacturing system is explained.

- Description: Abstract: The growth of the steel sector requires a fully integrated manufacturing system for real-time decision making. The primary challenge in the steel sector is the lack of data flow between the production operations such as Manufacturing Execution System (MES) and business systems as an example the Enterprise Resource Planning (ERP). The production operations of the steel sector require visibility of product quality, maintenance management, operational lead times, planning and scheduling, equipment health, to name but a few aspects. Legacy systems and technologies that are in the steel sector have plagued the organisation. State of the art technology implementations is defined as “brownfields” as they are deployed in silos with no standardisation across the organisation. Production data in the steel sector constitutes disparate sources as there is a multitude of processes and applications. Real-time data is collected and aggregated before being shared with other systems. The paper investigates current technologies and investments adopted by the steel sector and how to leverage off these existing expenditure to attain a smart enterprise and subsequently manage current and future steel demands efficiently. The paper defines an implementation approach and system architecture to assist the steel sector aligned to Industry 4.0. Industry 4.0 simplifies the approach to implement complex systems in a structured and logical manner in manufacturing organisations. Industry 4.0 integrates the operational equipment, people, processes, products and the supply chain. The study deliberates the Industry 4.0 framework and the approach to implement Industry 4.0 in the steel sector. The focus areas of the research include the review of Cyber-Physical Systems (CPS), Internet of Things (IoT), Industrial Internet of Things (IIoT) and Big Data at the steel entity. The Systems Development Life Cycle (SDLC) methodology is utilised in the research to gather information on the steel entity. A steel entity in South Africa is utilised in the research. Workshops and observations are employed at the steel entity to gather data and identify business processes utilised. The results based on data collated prove the viability of industry 4.0 in the steel sector. The alignment of the current system architecture of the steel entity to Industry 4.0 framework results in a reduction of thirty-four per cent in system applications utilised in the organisation which is presented in an Industry 4.0 architecture. Further benefits are defined in terms of reduction of integration interfaces, improved real-time data flow, financial savings based on a single data and reporting repository and reduction in month-end financial reporting timelines. , M.Phil.

- Description: M.Sc. (Computer Science) , Artificial Intelligence has been an increasing focus of study over the past years. Agent technology has emerged as being the preferred model for simulating intelligence [Jen00a]. Focus is now turning to inter-agent communication [Jen00b] and agents that can adapt to changes in their environment. Digital music has been gaining in popularity over the past few years. Devices such as Apple’s iPod have sold millions. These devices have the capability of holding thousands of songs. Managing such a device and selecting a list of songs to play from so many can be a difficult task. This dissertation expands on agent types by creating a new agent type known as the Modifiable Agent. The Modifiable Agent type defines agents which have the ability to modify their intelligence depending on what data they need to analyse. This allows an agent to, for example, change from being a goal based to a learning based agent, or allows an agent to modify the way in which it processes data. Digital music is a growing field with devices such as the Apple iPod revolutionising the industry. These devices can store large amounts of songs and as such, make it very difficult to navigate as they usually don’t include devices such as a mouse or keyboard. Therefore, creating a play list of songs can be a tiresome process which can lead to the user playing the same songs over and over. The goal of the dissertation is to provide research into methods of automatically creating a play list from a user selected song, i.e. once a user selects a song, a list of similar music is automatically generated and added to the user’s playlist. This simplifies the task of selecting music and adds diversity to the songs which the user listens to. The dissertation introduces intelligent music selection, or selecting a play list of songs depending on music classification techniques and past human interaction.

- Description: Abstract: The fourth industrial revolution has ushered in a technological era which promises a broader and quicker transfer of data and information captured in modern day systems than the third industrial age. This era promises great opportunity throughout numerous spheres of life with its greatest shortcoming being imparting the necessary skills and education on workers so as to survive in this era. The focus of this investigation is centred on the inequalities that women continue to face in the world of employment and the policies such as affirmative action and treaties that have been implemented to nullify these prejudices. Throughout history, women have succumbed to unequal working conditions as a result of unequal pay when compared to their male counterparts which further includes gender based acts such as harassment. To this end, women still face less favourable working conditions to that of men. The purpose of this study is to explore and understand the influence of the fourth industrial revolution on the future of the inequalities women face in work while analysing and deconstructing the implications of the Employment Equality Act alongside treaties as tools to reduce gender inequality in employment. The importance of higher education and skills development as solutions to alleviate the inequities women face in working conditions were investigated. A fundamental study further evaluated how legal reasoning interacts with social hierarchies based on gender and gender based implications. In doing so, the writer was able to assess the gender gaps experienced between men and women in employment. A law reform approach through work policy introductions were suggested in attempt to find solutions to aid women in work. Fundamental research was utilised in analysing the introduction of the fourth industrial revolution and the social impact it would have not only on women nationally but in African communities as well. The research study revealed that despite policies like the Employment Equity Act and the SADC Protocol on Gender and Development being implemented to aid in achieving equality for women in work, closing the gender based gap would prove challenging. The reason hereto is because men still dominate industries like Science, Technology, Engineering and Mathematics (or STEM fields) which are important for growth in an evolving society thus hampering the sustainable development of women. A country like South Africa, and most 4 | P a g e likely the rest of the African continent, will struggle to adapt to the advances imposed by the fourth industrial revolution due to a lack of resources and tools such as reliable infrastructure and electrical driven technologies to accommodate the new industrial age. Despite the suggestion of improving skills development and higher education in our society, unemployment and patriarchy still serve as obstacles toward achieving equal rights in employment for our women. In short, for newly suggested policies to work in light of the fourth industrial revolution, a legal and social reform will have to be adopted in society as a whole. , LL.M. (Commercial Law)

Extending labour law and social protection to waste pickers in the Fourth Industrial Age

- Description: Abstract: The world of work has changed significantly and continues to undergo changes brought about by the Fourth Industrial Revolution. These changes have contributed to a significant increase in informal employment where workers face a lack of adequate labour and social protection. The majority of the world’s workforce is engaged in informal employment, and in South Africa the growth in the number of workers in the informal economy has far outpaced that in the formal economy since the 2008/9 global financial crises. This dissertation therefore considers these challenges together with new challenges brought about by the Fourth Industrial Revolution. The rise of systems such as autonomous pneumatic waste management systems demonstrates the ability of new technologies to fundamentally alter the face of the waste management industries. It is against the backdrop of these potentially significant changes that this dissertation considers the need to provide waste pickers with adequate labour and social protection. It does so by firstly considering the protection available to these workers in terms of international and regional instruments. An analysis is also undertaken of the potential for new sources of international labour law, in the form of international trade agreements, to enhance compliance with international labour standards. This dissertation also considers the existing legal framework in order to identify deficiencies in regulation for the Fourth Industrial Age. To this end an analysis is undertaken of the valuable procedural safeguards provided to waste pickers, where new technologies are implemented, within the realm of administrative law. However, the practical ability to enforce these provisions are criticised given that cases brought in terms of the Promotion of Administrative Justice Act can only be heard by the High Court of South Africa. This dissertation then considers the World Economic Forum’s “human centred approach” to the Fourth Industrial Age. It is acknowledged that this idea by the WEF does not in itself represent a legally binding obligation, however, the internationally binding right to development and the constitutional obligation on municipalities to promote the social and economic development of the community similarly place people at the centre. The WEF human centred approach could accordingly guide interpretation of these obligations in the context of regulation for the Fourth Industrial Age. , LL.M. (Mercantile Law)

- Description: Abstract: Artificial Intelligence (AI) advanced technologies are growing and changing many industries. This paper will assess the relationship in which artificial intelligence impacts the performance of the workforce in a South African bank. The research explores the aspects that contribute to which a worker has improved productivity and performance through the adoption and use of artificial intelligence. The research considers the aspects of artificial intelligence toolset and their influence on the workforce performance. In addition, the paper assesses these aspect as to how they contribute towards the productivity with considerations to the integration of analytical and organized strategies that advance the workforces performance. The purpose is to improve the workforce’s quality performance in the banking institution of South Africa. The research has applied the descriptive statistics with the use of frequency distribution tables and graphical representations to analyze and present the information on the variables. The outcomes are evaluated with regards to the descriptive statistics and inferential statistics based on the variables which show that artificial intelligence has a relatively strong impact on workforce performance. Therefore, it is essential and recommended for banks to integrate them. The next frontier for shared services may be far more exciting, incorporating greater computing power and artificial intelligence into robotics, so that the lines between human judgment and automation become blurred.
