A COMPARATIVE STUDY BY COMPUTER TO DETERMINE THE OPTIMUM MAINTENANCE POLICY USING A PROBABILISTIC MODEL
Abstract
Selection the appropriate and optimum maintenance policy at any industrial plants is one of the important decisions that impact on competitive advantage which requires the study of all the factors surrounding the maintenance and discuss the results. decision-making between the implementation of the police of preventive or emergence maintenance in industrial company on several factors such the type of product and production quantity and the use of the product and machines age and the cost, maintenance of the machine and equipment during the specified period of time. The types of maintenance can be divided into two main types: preventive maintenance &Emergence Maintenance.The aim of the research is use probabilistic model to determine the optimum maintenance policy and deciding when to maintenance, through an economic comparison between the costs of preventive & Emergence maintenance that based on:-1-probability of Breakdown during periods of time. 2-Repeat the Breakdown during previous period’s time.The Researcher used MS-Excel program in building a probabilistic model to solve this problem& apply Practical application at the General Company for Leather Industries at men's shoe manufacturing plant (the production line (7)) .we found preventive maintenance is most economic police rather than emergence police.
