Replacement Model for Higher Education Institution Hostel Building Maintenance in Malaysia

Abstract

This paper is part of an ongoing research on the development of maintenance management cost model for Higher Education Institution Hostel Buildings in Malaysia where the case study is conducted at Kolej Universiti Islam Melaka (KUIM). The model is developed to analyze the total cost curve for various values of the uncertain parameter, and noting the effect of this variation on the optimal solution.The methodology in the context of the framework for decision areas addressed are those in which the replacement action are assumed to be known with certainty. This is due to the item is not subject to failure but consider the operating cost with use. The study is aimed to assist engineers in deciding an appropriate replacement policy. This is usually useful to plot the total cost per unit time curve. The advantage of the curve is that, along with giving the optimal value, it shows the total cost around the optimum. If the curve is fairly flat around the optimum, it is not really very important that engineers should plan for the replacements exactly at the optimum. The model is proposed to guide and facilitate when dealing with optimization problems. If there is uncertainty about the value of the particular parameter required during the analysis, then the replacement cost is unsure. Furthermore the evaluation of the total cost curve for various values of the uncertain parameter could in consequence affect the optimal solution.
