A Three-Phase Inspection Policy Based on a Three-Stage Failure Process

Abstract

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.

Research on Complex Structures in Space Fault Network for Fault Data Mining in System Fault Evolution Process

“…At present, there are a few studies on SFEP. The research includes mechanical system fault evolution [1]; grid cascading fault evolution [2]; multi-focus strategy optimization model [3]; competitive fault model [4]; hybrid fault model [5]; multi-strategy evolution dynamics [6]; online knowledge community knowledge system evolution [7]; innovation ecosystem performance [8]; urban traffic system evolution [9]; enterprise system evolution [10]; software spatial structure evolution [11], enterprise system evolution [12], and behavior process evolution [13]. The complex structure representation and analysis methods of the system have been studied and applied in medical field [14], project management [15], software evaluation [16], health analysis [17], monitoring video analysis [18], parallel structural analysis [19], and teaching activity analysis [20], Adaptive fault tolerant control [21], Active fault-tolerant control [22], Observer-based leader-following consensus [23], Adaptive Consensus Control [24] etc..…”
