- ItemApplication of lean tools in the supply chain of a maintenance environment(Southern African Institute for Industrial Engineering, 2017) Fourie, Cornelius Jacobus; Umeh, Nicholas E.Historically, Lean thinking has limited applications in the maintenance environment (that is, a non-manufacturing environment). This article reports on the Lean tools that can be implemented in the maintenance environment. To achieve this, a typical supply chain management of a rolling stock service organisation was used for analysis and validation. The approach was initially to map the current supply chain process through a standard method of value stream mapping so as to identify non-Lean activities. After mapping the current state, other suitable Lean tools for the current supply chain management were applied. Finally, performance Indicators were formulated for continuous review and assessment.
- ItemA decision-making framework for effective maintenance management using life cycle costing (LCC) in a rolling stock environment(Southern African Institute for Industrial Engineering, 2016) Fourie, Cornelius Jacobus; Tendayi, Tinashe GeorgeENGLISH Abstract: In this paper, a life cycle costing (LCC) framework for effective maintenance management is investigated and developed for use in a railway rolling stock environment. The framework consists of combining typical mission-critical components together with their failure and maintenance history. All costs related to the operation and maintenance of these components throughout their life cycle are also determined. The next step involves considering different scenarios under which the components can be used in relation to operations, maintenance, and replacements. The decision about which scenario to take is based on the one with the most favourable net present value after life cycle costing is performed over a specified period of time. A typical railway rolling-stock maintenance organisation in South Africa was used to highlight the practical implications of such a framework and how the company could make informed and appropriate decisions. The conclusion of this study is that such a framework is useful, and that it can be used as a basis for estimating LCC across a spectrum of critical assets found in the rolling stock environment.
- ItemDetermining the suitability of a business process modelling technique for a particular application(SAIIE, 2015) Geyer, Rian W.; Fourie, Cornelius JacobusOrganisations formally define and document their business processes in order to understand them and, subsequently, to enable continuous development, improvement, and management. Organisations can use business process modelling (BPM), which represents the design of graphical models that portray their business processes, to define and document their business processes formally. It is difficult, however, to select a suitable BPM technique in support of a specific application of BPM, owing to the considerable number of existing BPM techniques, the impact of their varying capabilities, and the lack of available formal measures to support evaluations of their suitability for specific modelling applications. This article presents a measurement framework to evaluate the usefulness of BPM techniques in specific modelling applications. It also presents the use of this measurement framework to determine an applicable BPM technique that can be applied in a specific modelling case.
- ItemAn examination of the relationship between supply chain management practices and business performance : a case analysis of a passenger rail company(Southern African Institute for Industrial Engineering, 2018-08-31) Fourie, Cornelius Jacobus; Chimusoro, OliverENGLISH ABSTRACT: The lack of maintenance engineering performance is one of the main causes of poor service delivery. In a passenger rail company, maintenance engineering performance is measured using several parameters, which include the ability of the organisation to upgrade and replace its fleet, the availability of spares, skills availability, information flow, and information technology. The aim of this study was to investigate the situation in a passenger rail company in South Africa in order to determine whether its supply chain management practices would influence business performance and, in this case, maintenance engineering performance. After a chi-square test was done, the results showed that there was a positive influence by supply chain management practices on business performance.
- ItemA modelling framework for railway infrastructure reliability analysis(Southern African Institute for Industrial Engineering, 2017) Fourie, Cornelius Jacobus; Zhuwaki, Nigel TatendaENGLISH ABSTRACT: The maintenance and management of railway infrastructure plays a central role in ensuring the reliability and availability of rail transport. In a highly competitive transport market, the rail industry is required to employ new and innovative maintenance strategies that will position rail transport as an affordable and reliable transportation alternative. This can be realised through implementing maintenance strategies that prioritise efficient resource allocation. Application of reliability-based techniques to make informed decisions in maintenance management, with an overall aim of reducing operational expenditure while maintaining safety and efficiency, has been increasing. This paper presents a framework for the application of a reliability-based technique to evaluate the reliability of railway infrastructure systems.
- ItemSelection of a decision model for rolling stock maintenance scheduling(SAIIE, 2015) Asekun, Olabanji O.; Fourie, Cornelius JacobusRolling stock is the most maintenance intensive part of the railway system and therefore, the most vulnerable if maintenance is neglected. It is therefore, essential to have an efficient maintenance schedule for rolling stock components. A decision support model can be used to achieve this. However, selecting the appropriate model to achieve this is vital to the success of the decision support model. In this paper a practical way of selecting the appropriate model to develop a decision support for scheduling of rolling stock maintenance, is presented. A case study is used as a numerical example for the proposed framework.
