A system's MTTR allocation method based on the time factors

摘要

The maintenance allocation methods are important in the design and maintenance of product. However, these methods have lots of deficiencies in practical application, which is inconsistent with the purpose of the maintenance allocation. To allocate the system MTTR (Mean Time to Repair) to the subsystems more precisely and reasonably, a better model is needed. The aim of this paper is to develop a maintenance allocation model which can improve the applicability and operability, and solve the residue problem which exists in maintenance allocation. A simple case study is used to demonstrate how the model can be applied in a real case.
