—This paper is part of an on-going 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 analyse the total
cost curve for various values of the uncertain parameter, and
noting the effect of this variation on the optimal solution. The
decision areas addressed based on the replacement action that
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.
