Optimizing Preventive Maintenance Models
We deal with the problem of scheduling preventive maintenance (PM) for a system so that, over its operating life, we minimize a performance function which reflects repair and replacement costs as well as the costs of the PM itself. It is assumed that a hazard rate model is known which predicts the frequency of system failure as a function of age. It is also assumed that each PM produces a step ...
متن کاملModelling and optimizing sequential imperfect preventive maintenance
This paper deals with the problem of scheduling imperfect preventive maintenance (PM) of some equipment. It uses a model due to Kijima in which each application of PM reduces the equipment's e ective age (but without making it as good as new). The approach presented here involves minimizing a performance function which allows for the costs of minimal repair and eventual system replacement as we...
متن کاملPreventive maintenance models with random maintenance quality
In real-world environments it is usually difficult to specify the quality of a preventive maintenance (PM) action precisely. This uncertainty makes it problematic to optimise maintenance policy. This problem is tackled in this paper by assuming that the quality of a PM action is a random variable following a probability distribution. Two frequently studied PM models, a failure rate PM model and...
متن کاملLinear and nonlinear preventive maintenance 1 models 2
4 Preventive maintenance (PM) is a maintenance program with activities initiated at predetermined intervals, or 5 according to prescribed criteria, and intended to reduce the probability of failure, or the degradation of the functioning 6 of an item. In the literature, a number of PM models have been introduced to depict the effectiveness of PM. Based on 7 these models, approaches to scheduling...
