- Description: M.Ing. , The A-Darter integration on the JAS39 Gripen was a very unique program in the sense that the development of the A-Darter missile was still on going when the integration took place. This dissertation thus looks at the various activities that were necessary when doing an integration program of such a nature. Firstly a well-defined contract needs to be in place in order for the various parties to understand their roles in the program. A Statement of Work (SOW) also needs to be defined together with this contract; the minimum that should be considered is as follows: - Management - Operational Analysis - Aeronautical / Airframe Integration - Systems Integration - Flight Test and Verification - Integrated Logistics Support (ILS) The systems engineering process is also described in this mini dissertation; both the SAAB Product Development Process (PDP) as well as the INCOSE System Engineering Processes are described. The dissertation describes when and where in the process an integration process can take place and what the minimum requirements are. The logical flow is described in terms of the critical path that needs to be followed during the integration process. The dissertation describes the process from the physical fitment trials that need to take place to the final launch of the System Avionics Test Missiles (SATM). The risks and lessons learnt are also described in this mini dissertation, the input for these sections were from interviews of people who were critical in the success of the program. The major risks on the program were definitely the technological risk as two state of the art pieces of equipment needed to be integrated. Power requirements and adherence to MIL-STD 1760 were one of the other main risks. The vibration spectrum that Denel Dynamics had to comply to also proved a risk in the program. However all the risks were mitigated and hence did not have an impact on the program.

- Description: M.Com. (Business Management) , Abstract: For many organisations, as business needs change, the need for better decision support systems increases. Which is why many organisations today embark on a journey of transitioning from traditional way of doing business intelligence to self-service business intelligence (SSBI). As is with many a new technology, SSBI presents different challenges to companies, therefore, to effectively deal with these challenges, it is critical to align IT and business strategies. To get real value out of the investment made on SSBI, companies tend to outsource the implementation and management of the solution to known consulting firms to assist them with effective ways of dealing with challenges posed by the solution. Which is why this study embarked on a journey of developing a practical working framework for a consulting firm named C-firm, which can then be used as a strategy to deal with management constraints of SSBI for its clients. A single case study was conducted between C-Firm and its clients to explore management constraints of SSBI, which include data governance and management, supporting infrastructure, context, and systems integration, and to subsequently develop a practical working framework for implementing and managing SSBI solution. The interactive approach model by Maxwell Loomis (2003), informed this case study research design. The flexibility of the interactive approach model best suited this study because it allowed different components of the study to interact with each other. A conceptual framework, which is one of the components of the interactive approach model, helped the researcher to focus on those factors that could assist in gaining understanding of the management issues associated with SSBI and how C-Firm can assist its clients in dealing with those issues. The research choice for this study was mixed method, mixed-model research. This means quantitative and qualitative data were collected, and researcher used quantitative analysis procedures to report on the findings. Data collection instruments used were semi structured interviews and an online questionnaire with open-ended and close-ended questions. The empirical study involved gathering data from both C-Firm’s employees and its clients. The research participants were nineteen (19) BI developers from C-Firm, and from C-Firm’s clients’ nine (9) BI developers and five (5) BI managers. The key findings of the empirical study in terms of data governance and management, supporting infrastructure, context, and systems integration were then used to develop a...

Systems integration of an automated assembly

- Description: Abstract: Most research has focused on getting input from and simulating specific assembly processes. The most advanced simulation research is based on data-driven methods. The rest of the articles in my reference relating to simulation are based on case studies. Research in data-driven methods has consisted mainly in feeding data from the assembly into the simulation model. The data-driven simulation can, in some cases, make use of real-time assembly-plant data to input into the simulation model. Data-driven methods are meant to provide an integrated online data simulation technique that enables the modelling of system changes for the purposes of scenario studies and decision-making. Modern manufacturing systems mainly consist of processes and machines. Simulating an assembly process requires input from the production processes as well as a detailed study of the given manufacturing environment. This work is about creating a generic simulation program of an automated assembly which can be used to simulate a given family of assembly. This program is based on the generic algorithm/flow chart and generic assumptions to be used to simulate an automated assembly process. The generic program is based on Arena and Simio programs. In this generic program, the following parameters can be varied: number of workstations, number of components, and order of assembly, cycle time, time to assembly, component and workstation availability and buffer capacity. The Arena and Simio programs are based on six scenarios for Simio and ten scenarios for Arena (i.e. scenario 1 to Scenario 6 or 10, and scenarios 6 and 10 includes all workstations and components per program). The simulation program is to be applied to different scenarios. The differences between scenarios are reflected in the animation, and the output graphs, tables and diagrams. The program, the different scenarios, the input spreadsheet per scenario, the animation window, and the related table and output graphs are presented under Simio. The graphs are separated into components consumed and workstation utilisation. After each run, reports which include the utilisation of each workstation, the number of components used, and the number of products or assemblies are generated... , D.Phil. (Mechanical Engineering)
