【摘要】：随着经济和技术的快速发展,物流行业的信息化水平的发展显得越来越重要。然而,物流资源难以被统一表达,众多物流资源的整合需要依靠物流信息的共享来实现,以服务的方式灵活使用。面向服务的架构为物流资源充分利用提供了一种可行的解决方案。针对物流资源的特点,需要一种描述模型对其统一表达。此外,随着功能相同或者相似的服务越来越多,用户如何挑选更加合适的服务也成为一个巨大的挑战。对此本文做了如下工作。首先,针对物流资源目前无法统一表达的特性,提出了一种适合于物联网环境下的服务描述模型。本文对Web服务描述语言进行研究,结合物联网环境中服务的特点,将物流资源与该模型层次结构一一映射,用一种基于XML模式的描述语言对物流资源进行描述。物流资源得以被表达和管理,以Web服务的形式被使用。其次,针对众多功能相同或者相似物流服务难以选择的问题,本文通过研究服务的非功能性属性,提出一种基于服务质量(QoS)本体树相似度的匹配算法。该算法综合考虑了QoS本体树的结构、属性以及约束性方面的相似度。之后通过仿真对该算法的性能进行评估,仿真结果表明该算法具有良好的性能。最后,本文结合之前提出的物流服务描述与匹配模型设计并实现了一个物流服务选择系统。结合相应服务质量的评估指标体系,最终在该系统中实现对物流配送服务选择进行了演示。
[Abstract]:With the rapid development of economy and technology, the development of information level in the logistics industry is becoming more and more important. However, logistics resources are difficult to be expressed in a unified way. The integration of many logistics resources needs to be realized by the sharing of logistics information and flexible use in the way of service. The service-oriented architecture provides the full use of logistics resources. A feasible solution. In view of the characteristics of logistics resources, a description model is required to be expressed in a unified manner. In addition, as more and more functions are similar or similar, how users choose more appropriate services has become a huge challenge. This article is done as a work. First, logistics resources can not be unified. Based on the characteristics of the expression, a service description model suitable for the Internet of things is proposed. This paper studies the Web service description language and maps the logistics resources with the model hierarchy, and describes logistics resources with a description language based on XML mode. It is able to be expressed and managed and used in the form of Web services. Secondly, this paper proposes a matching algorithm based on the quality of service (QoS) ontology tree, which takes into account the structure of the QoS ontology tree, in order to solve the problems that are difficult to select for many functions of the same or similar logistics services. Then the performance of the algorithm is evaluated through simulation, and the simulation results show that the algorithm has good performance. Finally, this paper designs and implements a logistics service selection system based on the logistics service description and matching model proposed before. Finally, the choice of logistics distribution service is demonstrated in the system.
