Abstract

The reliability modeling and optimization of performance sharing systems (PSSs) are of vital importance due to their wide applications. Existing research mainly focuses on evaluating and maximizing the reliability of PSSs. However, in many practical systems, decision‐makers tend to prioritize the average cost of the system over its reliability. This paper studies the resource allocation optimization in common bus PSSs. In such systems, each unit has binary‐state random performance to satisfy the multi‐state random demand. The surplus performance can be shared via a common bus with transmission loss between the common bus and the unit. The performance allocation, performance transmission, and unsupplied demand incur costs. Resource allocation strategies are determined by optimization models considering different objective functions and constraints. Additionally, transmission loss between the common bus and the unit is considered. A genetic algorithm is employed to efficiently find the optimal allocation strategies. Numerical examples prove the effectiveness of the proposed models in improving system reliability and reducing system costs.

有传输损耗的公共总线性能共享系统中的最优资源分配

由于性能共享系统（PSS）的广泛应用，其可靠性建模和优化至关重要。现有的研究主要集中在 PSS 可靠性的评估和最大化上。然而，在许多实际系统中，决策者往往会优先考虑系统的平均成本，而不是可靠性。本文研究了普通总线 PSS 中的资源分配优化问题。在这种系统中，每个单元都具有二态随机性能，以满足多态随机需求。剩余性能可通过公共总线共享，公共总线与机组之间存在传输损耗。性能分配、性能传输和未供应需求都会产生成本。资源分配策略由考虑不同目标函数和约束条件的优化模型决定。此外，还考虑了公共总线和机组之间的传输损耗。采用遗传算法有效地找到最佳分配策略。数值实例证明了所提模型在提高系统可靠性和降低系统成本方面的有效性。

期刊介绍： Quality and Reliability Engineering International is a journal devoted to practical engineering aspects of quality and reliability. A refereed technical journal published eight times per year, it covers the development and practical application of existing theoretical methods, research and industrial practices. Articles in the journal will be concerned with case studies, tutorial-type reviews and also with applications of new or well-known theory to the solution of actual quality and reliability problems in engineering. Papers describing the use of mathematical and statistical tools to solve real life industrial problems are encouraged, provided that the emphasis is placed on practical applications and demonstrated case studies. The scope of the journal is intended to include components, physics of failure, equipment and systems from the fields of electronic, electrical, mechanical and systems engineering. The areas of communications, aerospace, automotive, railways, shipboard equipment, control engineering and consumer products are all covered by the journal. Quality and reliability of hardware as well as software are covered. Papers on software engineering and its impact on product quality and reliability are encouraged. The journal will also cover the management of quality and reliability in the engineering industry. Special issues on a variety of key topics are published every year and contribute to the enhancement of Quality and Reliability Engineering International as a major reference in its field.
