- Description: M.Ing. , This dissertation proposes a reliability management process for the development of complex electromechanical systems. Specific emphasis is the development of these systems in an environment of limited development resources, and where small production quantities are envisaged. The results of this research will provide a management strategy for reliability engineering activities, within a systems engineering environment, where concurrent engineering techniques are used to reduce development cycles and costs. In order to implement a successful reliability engineering and growth management process, the following objectives need to be met: To ensure that reliability is designed into the system under development by providing reliability design data to the system engineering and development teams. To optimise reliability testing resource expenditure by managing the reliability growth process through a design problem monitoring and solution management process. To ensure that system life-cycle costs are optimised through good reliability design choices. To provide an environment where reliability engineering is a integral part of the system engineering process so as to optimise the rapid development process while keeping development expenditure within acceptable limits.

- Description: M.Ing. , One of the primary aims of any nation is to enjoy as high a quality of life as possible. This can be achieved through a process of economic development whereby quality of life in general is improved as the national economy moves from a developing economy into an industrialised one. For some time now it has been suggested that technology, in its many different forms, is to a large extent responsible for enhancing and driving the process of economic development, whether this be the economic development of a particular region or of an entire country. The question therefore arises as to whether it is possible to establish a correlation between the level of technological expertise of a nation and its economic development. On the strength of the research results contained in this document, there does appear to be a definite correlation between technology and economic development. This conclusion is further borne out by studies, conducted by well respected researchers, which have reached a similar conclusion. Having established the validity of this relationship, the question of whether South Africa is positioned to take advantage of such knowledge is investigated. The study indicates that South Africa is indeed in a situation whereby maximum advantage may be derived from the concept of technologically driven economic development. This finding may be taken one step further in that, in reality, South Africa has very little choice but to adopt a strategy of economic development driven by technology. As a result, it is found that economic success in South Africa is to a large degree dependent on the ability of the government and other relevant bodies to establish and sustain a comprehensive, coherent and practical programme of technologically driven economic development.

- Description: M. Ing. , Iteration and rework are inevitable within the concurrent nature of complex modern day engineering projects. Effective communication and process coordination, as well as minimisation of these iterations and rework cycles are major contributors to the successful completion of projects. The majority of project management techniques being used does not account for cyclic flow of information which result in project schedules being developed without incorporating the iterative nature of designs. However, making use of the Design Structure Matrix technique will facilitate in illustrating and modelling the various interactions between engineering disciplines, and when incorporated in schedule development will result in more accurate lead time forecasts and less schedule overruns when executing projects.

A materials management information system (MMIS) in a steel industry

- Description: M. Ing. , Purchasing/procurement, materials management, supply chain management and logistics are strategic elements linking customer requirements with the possibilities of the market. Purchasing is establishing itself as a center of competence for the strategic alliances and development partnerships with suppliers, for the continual process of improvement and for strategic cost management in product development. Materials Management within the Steel Industry is primarily concerned with the planning, acquisition, conversion, flow, and distribution of raw materials to finished goods. Through the use of Materials Management techniques, a company can initiate cost reduction programs. These can include lower stock levels, reduction in number of vendors used, better quality of goods used, integration of supply chain into company's own value chain, etc. As such, it is important to have an integrated, supporting information system, which can supply valid, up-to-date information as and when required. This thesis investigates whether it is necessary or more advantageous to buy a ready-to-use system, or to write a custom system, to fulfil the before mentioned requirement. New technologies create the opportunity to do business more effectively. Managers must however, take responsibility for participating in the planning and design of the information systems. Many computer-generated reports are designed to enable managers to keep track of day-to-day operations and to monitor the use of resources. Through effective design these reports can help manage not only the use of resources, but also the total cost of ownership. Decision support systems are designed to support semi-structured and unstructured decisions in situations in which information is incomplete. They are developed to support decisions that are so different each time that it would be hard to develop a standard set of procedures for programming them. Such decisions may be specific and may relate to a one-time-only situation. A decision support system should enable the decision-maker to apply the right decision rule to a problem, rather than using standard rules that may not apply because of changing conditions.After a sample group tested the custom software system and completed the questionnaires, the information was summarised. The most important conclusion is that while the smaller, custom written system is not ideally suited for every application within a larger company, it will be ideal for a smaller company. Ease of adaptation and the financial impact also influences the final decision, where the easier to adapt, 'cheaper' custom system is more suitable to a small company.
