Hybrid genetic and particle swarm algorithm: redundancy allocation problem
International Journal of System Assurance Engineering and Management, 2019Redundancy allocation problem (RAP) is a non-linear programming problem which is very difficult to solve through existing heuristic and non-heuristic methods. In this research paper, three algorithms namely heuristic algorithm (HA), constraint optimization genetic algorithm (COGA) and hybrid genetic algorithm combined with particle swarm optimization ...

The robust redundancy allocation problem of series-parallel systems
2013 Chinese Automation Congress, 2013Redundancy allocation is a technique that has been widely used to improve systems reliability. In this paper, the interval analysis is introduced to represent imprecise component reliabilities, and an order relation is applied in the comparison of interval values.

A unified approach for multi objective redundancy allocation problem
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016This paper represents to solve the redundancy allocation problem (RAP) occurring in optimization technique. The past research of RAP is basically single objective, which is focused on optimization of only one objective. We can genuinely combine more important aspects like cost, volume and weight to this which will lead to a multiple objective ...

A differential evolution algorithm to solve redundancy allocation problems
International Transactions in Operational Research, 2012AbstractTo improve system reliability without changing its nature, three methods are proposed. The first method uses more reliable components and the second method provides redundant components within the system. The third method is a combination of these two methods.

Dynamic Programming Formulation of the Redundancy Allocation Problem
International Journal of Mathematical Education in Science and Technology, 1971Summary Dynamic programming formulation for obtaining the optimum number of redundancies at each stage in a system is explained in detail. It is also emphasized and illustrated by examples, that the ‘summation’ form of functional equations, as suggested in the paper, provide a faster solution to an otherwise computationally voluminous method.

Efficiently Solving the Redundancy Allocation Problem Using Tabu Search
IIE Transactions, 2003A tabu search meta-heuristic has been developed and successfully demonstrated to provide solutions to the system reliability optimization problem of redundancy allocation. Tabu search is particularly well-suited to this problem and it offers distinct advantages compared to alternative optimization methods. While there are many forms of the problem, the

Multiple Weighted Objectives Heuristic for the Redundancy Allocation Problem
IEEE Transactions on Reliability, 2006A new heuristic is proposed and tested for system reliability optimization. The multiple weighted objective heuristic is based on a transformation of the problem into a multiple objective optimization problem, and then ultimately, transformation into a different single objective problem.
