Optimizing Equipment Maintenance & Replacement Decisions

Optimizing Equipment Maintenance & Replacement Decisions


Course Objectives

The objectives of the program can be summarized as follows:

  • To focus on the techniques of optimization - the single most important thrust of this learning program. Whether the decision is about work-crew sizes, or the replacement of component-parts or entire equipment units, the concept of making the very best, most optimal, decision will be the principal concern of the training program. 
  • To equip the participating maintenance managers, planners and schedulers and engineers with the know-how to select the most appropriate analytical tools for their maintenance decision-making. 
  • Reflecting the growing focus of industrial safety and the profusion of safety-related litigation - think of transportation accidents, chemical spills, and mining disasters - the program will show how safety objectives relate to the optimization models, and will underline the advantages of having a well-documented and rigorously-executed program of maintenance and replacement. 
  • To introduce the critical decision-making topics that can make a significant difference to the in-service time of equipment, to the costs related to doing maintenance too often or too seldom, and the optimization of asset utilization. 
  • To not only cover the classic need-to-know material in the area, but to acquaint the participants with leading-edge and on-the-horizon approaches that they will encounter in the near future. 
  • Educational versions of four software packages will be made available to participants. The packages are: 
    • OREST for the optimization of component preventive replacement decisions 
    • PERDEC for the optimization of the economic life of plant and equipment
