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.
