Influence of data uncertainty on the optimum inspection period in a multi-unit system maintained according to the block inspection policy

Abstract

In the presented paper, authors focus on delay-time-based maintenance modelling issues. They present an analytical maintenance model for multi-unit systems. Implemented maintenance policy is the Block-Inspection Policy (BIP) that assumes performing inspection actions at regular time intervals of T. In the next step, the problem of data uncertainty is analysed. There is also investigated the sensitivity analysis of the proposed cost model due to probability distributions of system elements’ initial and delay times parameters change.
