Lifecycle maintenance scheduling of station with multiple categories of information

Abstract

This paper studies the lifecycle maintenance scheduling of the station under variable and uncertain working conditions. In the multi-specification and small-batch production, the variable production plan leads to the piecewise constant working conditions, and then the piecewise failure process of the station. A general model based on the modality composition method is developed to generate the piecewise failure rate function of the station. To present the impacts of the working conditions on the failure process, the condition-modality theory is introduced. Based on that, an experiment for the above general model is given, and the modality fusion method for the expected failure rate modality is developed. In the maintenance scheduling with uncertain working conditions, the sharing principle is introduced to incorporate the lifecycle information into the dynamic maintenance scheduling. It is observed in the comparisons that the dynamic maintenance scheduling with the sharing principle is more cost-effective than the final payment principle and the expected maintenance scheduling. The discussion suggests that the complete equal instalment principle, which is a simplified version of the sharing principle, is applicable in the industry.
