Optimization of inspection and maintenance strategies based on machinery degradation could improve the operation safety and manufacturing efficiency. In this paper, a novel non-fixed periodic inspection strategy will be proposed and applied in precognitive maintenance to monitor and repair a multistage degradation process. The overall cost function of each degradation stage can be individually constructed...
In this paper, we focus on automated manufacturing systems composed of AGVs as material handling devices and jobshop layout of machines. AGV carries the raw materials through the shops in batches. In each shop an inspection unit is configured (multi stage inspection). Considering the size of the batches and the defect rate, one type of the inspection (sampling inspection or full inspection) is carried...
New API structural integrity management recommended practice and post-hurricane inspection bulletin, MMS proposed changes to CFR's on decommissioning, and increased interest in developing risk based inspection plans for offshore assets require better understanding of reliability principles. This paper will discuss the fundamentals of RBI from a practical viewpoint and gives details of recently published...
In this paper, we propose a Petri net-based stochastic model for the simulation and evaluation of complex maintenance activities for the Belgian power system. The main objective of this modeling approach is to develop a decision-aiding tool in order to improve the maintenance and renewal decisions in terms of their consequences on the total maintenance costs and on the global performance of the power...
