Value Assessment Method for Evaluating Preventive Maintenance Activities.

摘要

Because the advantages of preventive maintenance (PM) are difficult to quantify and returns are often seen only in the long term, PM operations are subject to frequent economic reviews. Maintenance managers need both technical and cost data on each maintained unit to build an effective, low-cost maintenance program based on a practical cost benefit balance between scheduled (preventive) and repair maintenance. The objective of this research was to develop a standard method to help maintenance managers at military installations determine the relative value and cost-effectiveness of PM activities. Information gathered by surveys and site visits was used to create a foundation for selecting and performing PM tasks. This foundation, the Value Assessment Method, was then used to develop a method for defining the value (or importance) of a PM activity based on the mission and the cost-effectiveness of the activity. The automated system proposed by this report will be adapted and programmed as a module in a commercial package (MAXIMO by PSDI). If field tests are successful, an upgraded version will be provided to the U.S. Army Engineering and Housing Support Center for distribution to Directorates of Engineering and Housing.
