Planning for Optimum Maintenance Cost in Water Treatment Plants in Baghdad

Abstract

The main objective of this paper is to develop model to reach breakeven point between periodic planned maintenance and emergency maintenance. Hence, intensifying periodic maintenance would lead to cost increased, accordingly the emergency maintenance should decreased and visa verse. The effect of this intensifying periodic maintenance on emergency maintenance is to be determined using simulation model based on data collected for 8 working water treatment plants. Many attempts have been seen to reach this point in Morocco and Australia, however , definitely the circumstances are different from firm to another and from country to another this paper is an another attempt to prove the ability to reach optimum point of  total maintenance cost. After much iteration the result will be optimum maintenance cost. The suggested model represents a flexible technique to reach the optimal point for total maintenance cost through the process of balancing between and periodic and emergency maintenance costs.
