Abstract

This paper presents the development of an efficient method for use in obtaining the best time between coordinated overhauls for a group of machines. The method is capable of stating the overhaul frequency of each machine within this time period. For convenience in the formulation of the model, maintenance schedule was divided into two parts, namely minor and major maintenance schedules. During a minor maintenance, an individual machine is checked and reset, while during a major maintenance, all machine are checked and reset simultaneously. Generally, their model determines the best value of the time between major maintenance and frequencies of minor maintenance, for each machine within this time span. In order to minimize the total cost of repairs and production. A numerical application of this development model in a case study is presented.

Key words: Maintenance, modeling, scheduling, optimization.
