Abstract:
This paper studies the Quality of Service(QoS) evaluation criteria of Web service and the computing model for composite service, meanwhile establishes the evaluation system of customer perspective-oriented quality offline, including reasonable degree of cost, conformity of service and satisfaction of service. It proposes the model of customer perspective-oriented Web service integration and optimization with the constraint condition of service cost. Analysis result shows that, compared with the model of QoS-based composite service selection, this model considers the attributes of service quality, in essence, quality of service(goods) offline which are cared by end users.
Key words:

摘要: 研究Web服务组合网上服务质量(QoS)的评价指标以及组合服务QoS计算模型,建立一种面向客户视角的网下服务质量评价体 系,包括服务费用合理度、服务与描述符合度及服务满意度。以服务费用为约束条件,提出一种的面向客户视角的Web服务QoS集成与组合服务优化模型。分析结果表明,与基于QoS的组合服务选取模型相比,该模型增加了服务质量指标,即网下服务(商品)的质量,更能满足客户需求。
