Multi Objective Availability optimization of systems by Allocating Redundancy Components with linear and nonlinear Constraints Hossein Zoulfaghari h zoulfaghari@in iut ac ir Date of Submission 2013 06 02 Department of Industrial and Systems Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Ali Zeinal Hamadani hamadani@cc iut ac ir Abstract Nowadays due to the complexity of the systems and the competitive conditions in the markets and industries it is essential to reduce production costs and having systems which are capable of being used in sensitive conditions This task leads to the fact that reliability and availability concepts become more important than before The reliability and availability are among the most important characteristics in complex systems especially in electronic and mechanical systems of avionics internet networks telecommunication systems power generation systems weapons etc In this dissertation the multi objective availability optimization for a series parallel system by using the redundancy allocation and availability redundancy allocation problems are investigated The main contribution of this study compared to the previous studies is in the assumption of component types Unlike the previous studies which assumed that all components are either repairable or non repairable in this study it is assumed that both repairable and non repairable components are used simultaneously in the system Moreover the effect of using dissimilar components in subsystems is compared with using only the same components in subsystems In order to solve the mathematical models the NSGA II algorithms as one of the best multi objective evolutionary algorithms is used Keywords Availability Reliability Redundancy Allocation Availability Redundancy Allocation multi objective Optimization PDF created with pdfFactory trial version www pdffactory com
