- Description: M.Ing. , Potential variation in tasks and relative location of manufacturing equipment (machine tools, robot, automated guided vehicles etc.) resulting from the need to restructure the production environment, require efficient and effective communication for optimal performance. The work presented makes use of information and data flow within a system to achieve an integrated and dynamic environment. Models are presented to describe the integration of processing and auxiliary equipment and to select auxiliary equipment for a specific environment. An analytical approach is included for the integration. Specific examples are included. The work presented attempts to contribute to the flexibility of modern manufacturing environments by integrating all facilities in the environment.

- Description: The aim of this paper is to analyse the key profit drivers in a manufacturing concern, and develop a decision tool based on optimisation techniques. The aim is planning and managing these profit drivers so that the target revenue and profit are realised during an operating period. This was done through developing a forecasting tool based on Visual Basic that was used by the organisation to project the future demand of its products. This tool was linked to a database that had details on past product performance. Planning software was developed using linear programming, which identified the optimum product mix and the sales outlets locations to maximise revenue and profit

- Description: M.Ing. (Engineering Management) , Manufacturing challenges originate from product design requirements that exceed available technology and manufacturing capabilities, or from assembly requirements that represent limitations to the ease at which product manufacture may occur. These challenges result in engineering designs having to be constantly modified to match technology or process capabilities. In order for manufacturing companies to attain competitiveness through their engineering design activities, adopting the design for manufacture and assembly philosophy is paramount. It is a philosophy that is capable of bridging the gap that exists in understanding manufacturing related challenges for more efficient and cost effective operations. Various design guidelines and considerations were evaluated to develop a design for manufacture and assembly framework, with the purpose of providing a common language between designers and the manufacturing engineers. Current manufacturing technologies were evaluated as a means of elaborating on the needs, challenges and opportunities in industry better. Data was collected to validate the framework by means of communication case studies between design departments, industry specialists and manufacturing workshops during site visits. The concept of the design for manufacture and assembly framework should have the potential of being applied on a global scale for companies, willing to outsource manufacturing work internationally.

Design-build delivery : a method to reduce delays in the South African construction industry

- Description: Abstract: Delays during construction are a global problem which results in large cost to the construction industry. Delays are common in construction projects and cause considerable losses to all parties involved. The construction industry continues to struggle to cope and to implement measures to either mitigate the impact of a delay, or prevent the delay altogether. The construction of large public and private sector facilities is still largely implemented through a project delivery method named design-bid-build otherwise known as the traditional project delivery method. The traditional method of project delivery is still used as it is considered to obtain the lowest cost for the client and protect their interests with the expected guarantee of a sound engineering job. However, it has been found that design & build methods are beginning to produce better results than traditional methods. The objective of this research was to determine the impact of a construction project delivery method on the prevalence and effect of delays, with the aim of proving a reduction in overall delays through the use of the design & build delivery method. This study made use of two similar case studies which differed largely by the project delivery method used. The case study method was chosen for its ability to determine operational links over a period of time, instead of simply determining frequencies of specific occurrences. The method used provides insights into organisations and gives an in-depth understanding of the topic being studied. Analysis of project documentation was performed along with semi-structured interviews. Themes were generated and compared with documentation allowing in depth analysis of each case. A comparison was then performed between cases and conclusions made from the findings presented. It was found that design & build was able to reduce the impact of civil, variation order and consultant related delays. No impact was found between methods for delays related to design changes and the contractor. Most significantly, it was found that delays related to the client were increased drastically under the design & build method, due to a break in the responsibility required for the successful implementation of design & build projects. This had the single largest effect on schedule overrun, and as a result meant that the use of the design & build delivery method may not necessarily reduce delays. However, future research into the performance of design & build was recommended where all work is maintained within the contractor’s scope, thus allowing a more accurate representation of the method. , M.Ing.

Production planning and control of plastics recycling : a life cycle analysis

- Description: Abstract: Through the increased use of plastic products within organizations worldwide, efficient tools and techniques are required for the effective reuse and waste management of these plastic resources. Plastic recycling technologies include four stages of plastic recycling, these include primary recycling, secondary recycling, tertiary recycling and quaternary recycling. Each technique is suitable for a certain plastic type and produces different forms of end products. The most common recycling technique has been found to be secondary recycling. This is evident from a series of past work that focuses on secondary recycling. Fewer research borders on the rest of recycling techniques especially primary recycling and quaternary recycling. The implementation of the recycling techniques is found mostly in external recycling facilities. Original equipment manufacturers (OEM) rarely implement plastic recycling as part of their production process. The objective of this research is to conduct a life cycle analysis on the secondary recycling process in order to highlight the stages of highest negative environmental impact within the process as well as analyse the production planning techniques and the constraints or requirements in the system and recommend improvements. The recommendations made are to improve the production process by reducing waste, reducing lead time, improving production planning techniques, improve the factory layout and through the life cycle analysis to reduce the environmental impacts which could reduce costs, improve processes, and increase the value added in environmental protection through the reduction of the impacts. The suggested improvements are to be sustainable and not of a great cost to the organization... , M.Ing. (Quality and Operations Management)
