An overview of the recent advances in delay-time-based maintenance modelling

Failure Prediction of Polymerase Chain Reaction Thermal Cycler

“…However, since there will be fluctuation due to noise at the measurement temperature and measurement time, it can be estimated by the width of the derivative function of the step response. The width of the function is obtained by the second order moment [3]. The two methods of finding the rise time are named as 'direct difference' and 'derivative width', respectively, hereafter.…”

“…Equipment management is performed by corrective maintenance (CM) and by periodic preventive maintenance (PM) before the failure [1][2][3][4][5][6][7]. The development of the internet of things (IoT) technology allows even low-cost equipment to send sensor data to the cloud, changing the paradigm of equipment management [7].…”

Optimization of Time Delay based Preventive Maintenance using Markov Decision Process

“…Maintenance with the time delay analysis was first introduced in 1973 by Christer and Wang [9] and Wang [10][11][12]. It continues to develop to be applied in many industries [13][14][15].…”

Inspection optimization model with imperfect maintenance based on a three-stage failure process

“…A defect can be identified if the inspection is carried out during the delay-time stage. Many inspection and PM models, especially successful case studies based on the two-stage failure process have been reported with actual applications in industry [18,19].…”
