Many engineering systems are exposed to run in load-varying environment. Load has a significant impact on the deteriorating process of components and system. Distributing the loads optimally among components of a system can reduce the failure probability and prolong the system life. In this paper, an approach to load distribution for multi-state systems under selective maintenance strategy is developed...
Many mechanical components exhibit more than one failure mode; and not all components under study have been exposed to similar operating conditions. For example, components may have been used in different operating environments or there may be differences in design and/or material. In these cases, life time data of components would not fall on a straight line on a Weibull probability paper (WPP),...
This paper introduces a proposed model to evaluate the reliability of multi-component degradation systems suffering two kinds of competing failure causes: internal degradation process and damage from external random shocks. The internal degradation is expressed as a random process with respect to working time, and a geometric process is employed to describe cumulative damage caused by external random...
