Supporting maintenance scheduling: a case study

Abstract

This work intends to incorporate in a computerized maintenance management system (CMMS) a scheduling support tool that, given a set of preventive maintenance tasks and the availability of equipment and technicians, returns a scheduling solution for a given time period. The tool is based on an algorithm that aims to minimize the total tardiness. The algorithm sorts, initially, the maintenance tasks by a critically index equipment and by tasks due date. Then the tasks are assigned checking previously if necessary spare parts are available. An application example is provided to show the proposed algorithm effectiveness.
