System Reliability Optimization using Redundancy Allocation with multiple component choices Mahsa Khaksefidi m khaksefidi@in iut ac ir Date of Submission 2012 1 2 Department of Industrial Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Gholam Ali Raissi Ardali raissi@cc iut ac irAbstractReliability is an important feature in the mechanical and electrical systems which is discussed in thecommunications industries internet networks telecommunication systems power generation systems manufacturing facilities and etc Finding the optimal level of reliability based on system constraints is calleda reliability optimization problem The variety of system structures and resource constraints for improvingthe reliability has led to design and analyze several optimization models One of the methods to improvesystem reliability is using the redundant components in the system it has proven that Redundancy AllocationProblem RAP is a kind of NP hard problems and the computation grows exponentially by increasingproblem size and constraints Hence finding the appropriate solution is important for these problems In thisthesis the redundancy allocation problem is studied for improving the reliability of series parallel systemsbased on the multiple component choices and ant colony algorithm has been applied for the purpose ofsolving The present study investigates reliability optimization and system requirements in terms of bothelectrical and mechanical systems and suggests a new solution based on ant colony algorithm In mechanicalsystems maximizing system reliability minimizing system cost minimizing system weight andsimultaneously optimization of the reliability cost and weight of the system was studied based on themultiple component choices subject to the weight and cost and minimum reliability constraints Thismechanical system has been studied by different authors and the suggested algorithm has indicated betterperformance in comparison with the previous approaches In order to illustrate the application of theredundancy allocation problem and performance of the proposed ant colony algorithm an electrical systemwas also evaluated Considered system is an electronic board which is used in medical equipments and now itis produced by the Isfahan Optics Sa Iran Company In this equipment in addition to cost and weightconstraints it is necessary that the volume constraint dimensions of system be also considered Adding thevolume constraint system dimensions has not been studied in the multiple component choices so far and itis also discussed in this thesis In electrical system maximizing system reliability and minimizing systemcost was studied based on the multiple component choices subject to the cost weight volume and minimumreliability constraints The present study has suggested an appropriate algorithm and solution for solvingreliability optimization problems in series parallel systems based on redundancy allocation Key words Reliability Optimization Redundancy Allocation Problem Ant Colony Algorithm Gear trainsystem Isfahan Optics Sa Iran Company
