Reliability analysis of two dissimilar parallel unit repairable system with failure during preventive maintenance

Article history: Received October 28, 2015 Received in revised format November 28, 2015 Accepted January 28, 2016 Available online February 1, 2016 The main purpose of this research work is to present a reliability analysis of a two dissimilar parallel unit framework under the presumption that a framework’s unit may also fail during the preventive maintenance (PM). Only one repair man is available with the system. It has been assumed that he is well capable of doing every repair work including preventive maintenance. Here in this work we have assumed that failure and repair times of each unit are correlated. Utilizing regenerative point strategy different reliability attributes are obtained which are very much helpful to system/ framework designers and company managers. Graphical practices of mean time to system failure and profit/cost function have been studied. © 2016 Growing Science Ltd. All rights reserved.
