Kaedah Pengukuran Indek Kebolehsenggaraan Produk atau Sistem Berdasarkan Kriteria Pemasangan

This paper discusses the relationship between maintenance and the selection of fastener in order to enhance product performance in terms of life time and physical structure. In this study, maintainability index was measured using a disassembly digraph, which was evaluated due to the fastener used and the assembly criteria. The critical path was used to represent the shortest and simplest way to achieve the targeted component or part. Additionally, the rate of maintenance was also taken into consideration. To clarify the method developed, a case study of water pump was carried out. Result indicates that by changing the type of fastener, maintainability index can be increased tremendously.
