Zhang, M., Ye, Z. & Xie, M. A Condition-Based Maintenance Strategy for Heterogeneous Populations, Computers & Industrial Engineering, 77, 2014, 103 - 114Abstract:
This paper develops a maintenance strategy, called inspection-replacement policy, to
cope with heterogeneous populations. Burn-in is the procedure by which most of the defective
products in a heterogeneous population can be identified and removed prior to being
placed in service. However, modern manufacturing is so well developed that a defective
product is able to function for a long period of time even under aggravated operational
conditions. Instead of weeding defective products out via costly burn-in tests, use can
be made of them in field operation where maintaining actions will be performed to prevent
early in-use failures. The inspection-replacement policy consists of an inspection,
conducted in an early stage with the purpose of identifying and replacing defective products,
and a preventive replacement, carried out at a later stage to prevent wear-out failures.
The preventive-replacement time is dynamically determined, depending on the information
obtained by the inspection. The inspection-replacement policy is compared with a
joint burn-in and age-based-replacement policy to show its practicability and competence.
