Constrained Reliability Redundancy Optimization of Complex Systems using Genetic Algorithm
نویسنده
چکیده
The paper presents a Genetic Algorithm (GA) approach for solving constrained reliability redundancy optimization of general systems. The advanced GA technique uses a dynamic adaptive penalty function to consider the infeasible solutions also and guides the search to optimal or near optimal solution. The penalty technique is applied to keep a certain amount of infeasible solutions in each generation so as to enforce genetic search towards an optimal solution from both the sides of feasible and infeasible regions. The performance of the method is compared with GA tool Box of MATLAB. Keyword—constrained redundancy optimization; GA, complex networks; metaheuristic algorithm.

Reliability Optimization for Complicated Systems with a Choice of Redundancy Strategies (TECHNICAL NOTE)
Redundancy allocation is one of the common techniques to increase the reliability of the bridge systems. Many studies on the general redundancy allocation problems assume that the redundancy strategy for each subsystem is predetermined and fixed. In general, active redundancy has received more attention in the past. However, in real world, a particular system design contains both active and col...

A redundancy allocation problem (RAP) is a well-known NP-hard problem that involves the selection of elements and redundancy levels to maximize the system reliability under various system-level constraints. In many practical design situations, reliability apportionment is complicated because of the presence of several conflicting objectives that cannot be combined into a single-objective functi...
