Reliability analysis of an extended shock model and its optimization application in a production line

Firstly,a two-unit cold standby shock model with multiple adaptive vacations is introduced,in which the startup and replacement of repair facility are also considered. secondly,using supplementary variable method and laplace transform,some important reliability indices are derived,such as availability,failure frequency,mean vacation period,mean renewal cycle,mean startup period,and replacement frequency. finally,a production line controlled by two cold-standby computers is modeled to present numerical illustration and its optimal part-time job policy at a maximum profit. © 2014 renbin liu.
