This paper treats an optimal inspection and maintenance policy of a continuous time Markovian deteriorating system, which minimizes the total discount,~d expected time in which the system is not operating. The problem is formulated by a semi·Markov decision process and some properties of an optimal policy are obtained, that is, a control limit rule holds and as the system degrades, an optimal i...
In this paper a multi-product production systems (MPPS) with in-line quality control is examined. The problem of determining the optimal inspection strategy that results in lowest total inspection cost, while assuring required outgoing quality level is modelled discrete-event simulation is used to model the production system. The optimal allocation is determined by using a tabu search algorithm.
Power line inspection plays a significant role in the normal operation of power systems. Although there is much research on inspection, question how to balance working hours each worker and minimize total hours, which related social fairness maximization benefits, still challenging. Experience-based assignment methods tend lead extremely uneven among working/inspection teams. Therefore, it grea...
BACKGROUND AND AIMS Lynch syndrome (also known as hereditary nonpolyposis colon cancer) is associated with an increased risk for colorectal cancer, which can arise despite frequent colonoscopic exams. We evaluated the adenoma miss rate of conventional colonoscopy in patients with Lynch syndrome, and compared the sensitivity of chromoendoscopy versus intensive inspection for detecting polyps mis...
We study a production-inventory system with multiple unreliable supply sources. Through inspection and rework the system can improve the quality of the units received from the supply sources. There are two interleaved decisions: the replenishment quantities from the sources and the inspection-rework quantities among the units received. We show the optimal solution to the replenishment decision ...
