OPTIMUM MAINTENANCE COST IN WATER TREATMENT PLANTSP.B VYASAbstract The main objective of this paper is to reach breakeven point between periodic planned maintenance and emergency maintenance, to reach this objective, periodic maintenance cost will be increased, then, itâs necessary that emergency maintenance should decreased and visa verse. The first step in this research was preparing a list of all maintenance activities to be done in water treatment plants according the history records of these plants, categorizing these activities into two main lists the first for periodic maintenance and the second for emergency. The next step is studying the effect of intensifying periodic maintenance on emergency maintenance. Using simulation model and starting intensifying periodic maintenance the effect will be determined calculating both periodic and maintenance cost and finally total maintenance cost. At the end of much iteration the result will be optimum maintenance cost. The suggested approach represents a flexible model to reach the optimal point for total maintenance cost through the process of balancing between and periodic and emergency maintenance costs. |
