  Abstract:
Weighted k-out-of-n systems form an important class of redundant systems with a wide range of applications in reliability engineering. In this paper, we introduce novel optimal preventive maintenance models for the class of weighted k-out-of-n systems based on some well-known criteria such as cost criterion and availability criterion. Using the concept of signature of the system and depending on the average number of failed components, we set up a cost (availability) function corresponding to the time that the total weights of the working components become less than a predetermined threshold m, or the age of the system reaches TPM. Some examples of weighted k-out-of-n are presented to demonstrate the proposed models numerically and graphically. A related sensitivity analysis is performed to illustrate the effects of the parameters on the proposed cost and availability functions.
