Maintainability and Linear Programming, A Quantitative Approach to Asset Allocation
Developing a plan for staffing and supplying complex maintenance schemes has been a challenge for R&M engineers and logisticians for many years. Many efforts based on reliability predictions, maintainability predictions and the ubiquitous "K-factors" have been used by the DoD and other government organizations in an attempt to assure adequate manpower and spare replacement units and parts without acquiring unnecessary quantities of these same resources. These approaches are expensive and tend to err on the side of oversupply. Many large commercial manufacturing enterprises, such as the auto manufacturers, desire an optimized, particularly for cost, maintenance and sparing solution. Linear Programming and similar tools have been in the purview of operations research for years, and academic papers applying Linear Programming or similar techniques addressing the problem in large industrial plants have been written. There is also mention of Linear Programming in Military Standards on maintainability, but no application detail or reference. Actual application is still not widespread. This presentation provides an overview of the maintainability problem, how Linear Programming works and how Linear Programming can provide optimized solutions as an introduction to a very powerful methodology.
