Accurate reliability and residual life analysis is paramount during the designing of requirements rotation power measuring equipment (PME). However, sample dataset failure usually sparse contains inevitable pollution data, which has an adverse effect on analysis. To tackle this issue, paper first applies nonlinear regression to fuse rate environmental features PME collected from various locatio...

Construction equipment is an important type of resources of heavy construction contractors. Since equipment breakdowns can cause project delays and significant financial losses, the contractors are eager to know those factors causing equipment failures directly or indirectly, related to equipment design, maintenance, and operations. Although Bayesian network can be used for diagnostic analysis ...

This paper analyses life cycle cost for equipment protected by both base and extended warranty policies from a consumer’s perspective. We assume that the equipment have two types of failures: minor and catastrophic. A minor failure can be corrected by a minimal repair whereas a catastrophic failure can only be removed by a replacement. The equipment is assumed to be maintained at no charge to t...

Internal heat of electrical equipment rises due to various reasons such as contact problems, unbalance loading, cracks in insulation, defective relays or terminal blocks, etc until eventual failure which can cause unplanned outages and possible injuries. Therefore, early prevention of thermal abnormalities in electrical equipment is necessary to avoid failure. Nowadays a fast, reliable, non-con...

In this paper, a real maintenance workforce-constrained scheduling problem is formulated as a bi-objective mixed-integer programming model with the aim of simultaneously minimizing the workforce requirements and maximizing the equipment availability. The skilled workforce is provided by internal and external resources using regular time, overtime and contracting. The equipment availability is m...

Failure propagation analysis is the cornerstone to assure safe operation, predicative maintenance for equipment integrated system. Study the failure propagation mechanism of complex system on the basis system directed network constructed. The grade diffusing process widely used is described with the fault propagation probability and constrains. According to the fault information of nodes and ed...
