Optimal Two Dimensional Preventive Maintenance Policy Based on Asymmetric Copula Function
Abstract: For some kinds of
products, the consumers have strict requirements to the reliability of these products
in the based warranty period. Then the manufacturer is inclined to provide the
two-dimensional preventive maintenance policy to take the usage degree of the
product into account. As a result, twodimensional preventive maintenance policy
in the warranty period has recently obtained increasing attention from
manufacturers and consumers. In this paper, we focused on the optimization of
based warranty cost and proposed a new expected based warranty cost model
considering the two-dimensional imperfect preventive maintenance policy from
the perspective of the manufacture. Asymmetric copulafunction was applied to
modeling the failure function of the product. And the optimal two-dimensional preventive
maintenance period was obtained by minimizing based warranty cost. At last,
numerical examples are given to illustrate the proposed models, of which the
results prove the model effective and validate.
