- Description: Abstract: One of the major concern striking the 21st century is the development of Sustainable Development (SD) whilst rising mankind welfare. Contemporary technology generally has controverting impacts over the concept of SD, as portrayed through the present power supply system. Low-priced, easily- available electrical energy is very important to various contemporary society ‘s most significant technologies and SD advances. Meanwhile, the immense mainstream of the global’ s electrical energy is produced by means of fossil fuels, which caused stern ecological burdens. Thus, any shift towards a sustainable, thriving future will necessitate resources of electrical energy, which can offer the benefits of current ‘s power production system whilst diminishing its harmful impacts. To achieve growing power supplies with negligible ecological effect, shift to the present electricity production practices are needed to take in augmented power efficiency as of fossil fuel burning technologies by introducing renewable energy sources into the market...

- Description: Abstract: Due to the fast growth of renewable energy resources, the analysis and comparison of costs associated with different forms of electricity generating sources are crucial for decision policy makers and investors. To this end, the Levelized Cost of Electricity (LCOE) is a widely tool employed to assess the economic viability of a power plant, however the issue with this tool is that it does not considers all the complexities involved. Thus, the Levelized Avoided Cost of Electricity (LACE) has been introduced to cover the elements ignored by LCOE, which are becoming critical to business decision. Despite the development of LACE, various studies continue using LCOE to evaluate the economic competitiveness of various power plants, especially in South Africa. To this end, this paper used both LCOE and LACE tools assess and compare the economic viability of 10 technologies which are: coal, gas, nuclear, biomass, geothermal, hydroelectric, wind offshore, wind onshore, solar photovoltaic, concentrated solar power. The results indicate that of all technologies, geothermal ranks at the first place as the most economic competitive alternative, followed by coal technology. Furthermore, the results illustrate that the worse technologies in terms of economic viability are solar photovoltaic, concentrated solar power, and wind. As far as the authors are aware this study is the first example in the context of the South African energy sector.

- Description: Abstract: Growing pressures from various players such as governments, non-governmental organizations, and customers have impelled business corporations to address the economic, environmental, and social issues associated with their supply chain activities. Consequently, the concept of sustainability has become a buzzword among scholars and industry practitioners. Although, the concept of sustainability is attaining high level of importance in Europe, America, and Asia due to its ability of ensuring environmental sustainability, in Africa the integration and application of sustainability’s concept is facing several challenges. To date, several studies were conducted to investigate the barriers affecting sustainability practices in mining sector at country’s level. However, an investigative study regarding the barriers of sustainability practices in mining sector of the Southern African Development Community (SADC), which involve fifteen African countries is missing, this paper aims at filling this gap. The data were collected through a quantitative approach. At least 1 423 participants were involved in the survey. The findings revealed that the major barriers blocking the development of Sustainable Supply Chain in mining industry of SADC region include Lack of commitment on environmental deterioration, lack of communication and knowledge sharing, Ineffective monitoring and control system, lack of effective policy and legislation direction, high cost associated with the implementation of SSCM, Poor Supplier Commitment, lack of green practitioners, poor senior managements’ commitment, lack of recycling activities. Lack of Political commitment and support, Lack of managerial support and practical tools, and inadequate individual capacity.

- Description: Abstract: The paper addresses the use of standard operating procedures as a key component to customer acquisition founded on assessment of research papers. It illustrates the application and importance of a standard operating procedure from different perspectives whilst emphasizing its critical relevance to customer research in small and medium sized enterprises in rural areas. The paper depicts how standard operating procedure, if understood by rural situated small and medium sized enterprises can be utilized as a component of a well-organized administration system, market penetrate tool towards sceptic and sensitive customers, and a competitive strategy over market competitors. In many small enterprises there is a basic lack of understanding as to what quality controls are necessary, let alone how to implement them. Standard operating procedures are prescribed forms that explain how a person or businesses perform a task. Standard operating procedures provide a step-by-step set of how-to instructions to the person or persons performing a specific task. Each standard operating procedure should be specific enough to be clear and understandable, but flexible enough to be useful. Standard operating procedures also define expected practices in an industry where quality standards exist...

- Description: For the last couple of years organizations have been urged to flatten their hierarchical structures in order to increase flexibility of employees and to empower employees with the decision making discretion. Flattening or delayering of organizational structures refers to the elimination of layers in a firm’s organizational hierarchy and the broadening of manager’s span of control. The decision to push down decision making to the lower levels of the organization presents employees with the freedom to be responsible for everything they do and also to be held accountable. Though it may have been suggested that flattened organizations are flexible and proactive, this paper will identify that through the flattened organizations managers still take the major decision regarding the organizations success and that the goal of flattening hierarchies isn’t always achieved after implementation.

- Description: The knowledge of lean principles is just as applicable to offices and other work environments as it is to manufacturing plants. Lean is a theory that can help organizations to simplify and organize their working environment so that waste can be reduced, avoid high employee turnover and proper equipment and workspace is used. Although services can be consumed and perceived, they cannot be measured easily and objectively, like manufacturing products. An objective measurement is a critical aspect of lean, which requires data-driven decisions to eliminate defects and reduce variation. Waste and the misuse of time could cost the company and the clients’ money and time, and in an academic environment, this is known to be extremely valuable. The study focuses on the finance department supporting students in one of the leading South African institution. There has been a number of incidents of wastage and non-professionalism identified in that department, which led to some students not getting their tuition and study material on time and some unable to register for the current year. The research attempts to highlight these problems and provides a solution as to how they can be resolved in order to assist the university to reach its expected throughput.

The application of theory of constrain (TOC) in an organisation to resolve problems and to boost productivity
- Authors: Kholopane, Pule
- Date: 2015-07-07
- Subjects: Theory of constraints (Management)
- Type: Article
- Identifier: uj:5249 , http://hdl.handle.net/10210/14855
- Description: The theory of constraints (TOC) identifies constraints which are otherwise labelled as waste by lean. It isolates these constraints and provide resources in order to buffer and/or eliminate them completely. Its underlying premise is that organisations can be measured and controlled by variation on three measures which are throughput, operational expense and inventory. TOC challenges managers to rethink some of their fundamental assumptions about how to achieve the goals of their organizations, what they consider productive actions, and about the real purpose of cost management in order to maximize throughput through sales. It is about understanding bottlenecks to a process and better managing these bottlenecks to create an efficient process. The paper identifies inputs that are causing constraints. It explains the methodology to isolates them and how and when to apply TOC in minimising their impact. In order to prove this, a research was carried out in the Bakwena mine in South Africa where TOC was used to resolve recurring problems. The end results has shown that when problem area are isolated, conditions observed, resources allocated at the problem area and action taken to address problems immediately, positive results can be achieved.
