- 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. (Engineering Management) , Abstract: The objective of the research is to formulate a simplified physical asset modelling framework that is universal to any industry or any asset type, for use in the chosen Computerised Physical Asset Management System (CPAMS) such that it provides the benefit of improved management of physical assets over its lifecycle. The research highlights that there are numerous CPAMS, whether branded as ERPS, CMMS, EAMS or CFMS as example, however the track record of providing organisational benefit given the significant initial and ongoing investment, is limited. The literature review highlights that the configuration of the CPAMS is one of the contributors to limited benefit, where configuration refers to the structuring and organisation of the CPAMS to do that which the user require. One aspect of the CPAMS configuration is the physical asset modelling framework within which the physical assets are recorded in the CPAMS along with its myriad of data, information and various settings. In addition to that which is entered by the user, the processing of various performances and reporting against the asset modelling framework is equally critical. The development of the physical asset modelling framework involved two independent approaches, firstly deriving a framework from literature review of reliability and logistics engineering theory, and secondly, a framework derived from the research of existing industry asset and asset hierarchy naming conventions, standards or frameworks. The theory-derived framework was validated by the existing industry frameworks with the difference that majority of the existing industry frameworks has an additional organisation level in the hierarchy. A single physical asset modelling framework was derived from the nine existing industry frameworks and since this also validated the theory-derived framework, the industry-derived framework was concluded as the universal simplified physical asset modelling framework. A CPAMS is a necessity for the optimised management of physical assets over its lifecycle to achieve levels of sustained performance required by the organisation’s long-term business strategy and real-time operations. A CPAMS has the potential to realise this optimised management, however, and this is to be emphasised, this potential is only realisable when the CPAMS is configured and maintained by skilled asset management professionals having detailed understanding of what is required for lifecycle asset management, and therefore how the CPAMS must enable this management. This research has developed one such critical requirement which is a universal simplified physical asset modelling framework.
