    The applicability of the centeno, chaudhary and lopez repair time standard methodology in a rail maintenance environment
    (SAIIE, 2015) Rommelspacher, Karl Otto; Fourie, Neels; Mutibura, Abel
    The establishment of labour standards within a production environment has become common practice, and is receiving growing recognition in the maintenance environment. However, the application of labour standards in a transit maintenance organisation has received limited attention. Centeno, Chaudhary and Lopez have developed a repair time standard methodology that has been applied in the transit bus maintenance facilities of three agencies in central Florida in the USA. An investigation into the applicability of this methodology in a rail maintenance environment in South Africa forms the basis for this study.

    ENGLISH ABSTRACT: The decline of the passenger rail transport system of South Africa over the past two decades has left the passenger rail industry in a difficult position. The most significant impact has been the deterioration of the physical assets. Due to the renewed focus by government on passenger rail transport, the need for improving the physical asset management has been recognised. Physical asset management manifests itself through the application of strategies. The need for new and/or updated strategies was identified and summarily examined. Through the initial literature study, it was found that strategies are founded on the specific maintenance policy of an organisation. The application of the new/updated strategies was intended to take place at Metrorail. An investigation at Metrorail revealed the lack of any significant policy that is required to develop any new strategies. This discovery led to a shift in focus from the development of new strategies to the development of a physical asset management policy. A generic policy statement called Requirement-­‐based Asset Management (RAM) was developed, with its primary focus being the conducting of maintenance activities based on the requirements of the organisation, the employees, the asset and the customer. In order to evaluate the suitability of RAM, a strategic roadmap was developed based on the policy statement and validated in three areas of Metrorail. These three areas were the wheel set maintenance system, the Top 7 fault evaluation procedure and the scheduled maintenance cycle of the train sets. The application procedure concluded that the roadmap and thus by deduction RAM are suitable for the Metrorail environment. RAM can be used to develop/improve an organisation’s physical asset management policy.
