摘要: 集群式供应链通过企业间的服务协作来实现大规模的定制化生产,Web服务的组合方法直接决定了协同的效能与成本。鉴于不同企业对协同服务的需求差异很大,而现有的Web服务组合方法往往只给出一种QoS评价模型,难以满足用户多样化的QoS需求,首先设计了多种QoS评价模型以及这些评价模型的组合,以此满足企业对协同服务质量可定制的需求;然后,将变异机制和精英保留机制引入最大最小蚁群算法,提出一种服务质量可定制的企业协同Web服务组合方法;最后通过实验验证了该方法的可行性和有效性。

Abstract: Through the collaboration mode between enterprises,Cluster Supply Chain (CSC) could realize the mass customized production.The existing Web service composition methods only evaluated one QoS evaluation model,which could not meet the diverse demands of different enterprises for collaborative service.To solve this problem,a variety of QoS evaluation models and the corresponding combinations were designed to realize the customization of collaboration service quality.By introducing the mutation mechanism and elite retation mechanism to the Max-Min Ant System (MMAS),a QoS-customized Web service composition method for enterprise collaboration was proposed.The simulation experiment results validated the effectiveness and feasibility of this algorithm.

Key words: cluster supply chain, enterprise collaboration, service composition, quality of service customization, max-min ant algorithm
