Analysis and Scheduling of Maintenance Operations for a Chain of Gas Stations

الملخص EN

Maintenance is one of the central issues in operational activities, which involve any type of equipment.

In this paper we have considered analysis, modeling, and scheduling of preventive maintenance operations for fuel dispensers in a chain of gas stations.

A gas station company with more than 570 dispensers in more than 40 stations is considered and the maintenance problem is studied in detail.

Operations research tools, including maintenance models and linear programming, were used to establish optimum schedules for preventive maintenance operations.

Detailed cost analyses were carried out to determine feasibility of the proposed preventive maintenance schedules.

Models and procedures presented in this paper could guide operation engineers and maintenance managers in solving similar problems for operational improvements.
