Abstract In this paper, the authors’ research work is focused on imperfect inspection policy investigation, when not all defects are identified during inspection action performance. They are interested in Block Inspection Policy performance for multi-unit systems, the maintenance policy which is one of the most commonly used in practice. As a result, at the beginning, few words about delay time modelling approach and a brief literature overview is given. Later, the model of Block-Inspection Policy is provided. The numerical example with the use of QNU Octave program is given. In the next Section, the sensitivity analysis of the developed model is characterised. The article ends up with summary and directions for further research.

The Cost

This paper proposes a three-phase inspection policy model based on a three-stage failure process for a single unit system. Different from existing works which usually assume unique inspection interval, the three-phase inspection policy allows the inspection policy to change according to the identified state of the unit. The possible renewal scenarios are considered based on which the cost model is proposed. Numerical example is presented, and the results clearly reveal the advantage of the three-phase inspection policy over the unique interval inspection.

Inspection Policy

We present a new inspection policy useful when testing is needed to detect failures of a single-unit system. It is supposed that tests may fail and give an erroneous result. The inspection policy minimizing cost per unit of time for an infinite time span is also discussed. In addition, we study the behaviour of the optimum policy for some time to failure distributions often assumed in reliability: exponential and Pareto.
