摘要
计算环境的变化使得服务化正成为当今信息社会各类资源共享的主要商业模式,信息系统也完成了从以企业自身为中心专注内部管理的管理信息系统向以客户为中心关注整个供应链的ERP系统的演变,物联网时代的到来,使得新型的基于物联网的信息系统呼之欲出。从远洋渔船及其作业系统需求出发,以面向服务的架构SOA为指导,提出并构建了远洋渔船物联网智慧服务系统,探讨基于新型物联网智慧服务系统的开放式服务构件架构模型及系统功能;由于实际应用中,系统的服务构件关系的表达和管理往往比较复杂,服务构件间的冗余及整体关系难于掌握,论述了基于Petri网的系统中各构件服务关系动态表达方法,该方法能增强使用者对服务构件库的整体掌握能力,便于发现服务构件间的求解冲突与冗余,并提供了直观的服务构件的组合配置图示机制,提高了系统智能,发挥了SOA架构的优势。同时进行了实验仿真,证明了方法的可靠性。
The change of the computing environment makes the servitization become the main business model of all kinds of the resource sharing in the modern informationized society.The information system has accomplished the evolution from enterprise-oriented MIS focusing on the internal management to the client-oriented ERP concerning the whole supply chain.The arrival of the Internet of Things（IOT） summons the new type of information systems based on IOT.Founded on the requirements of pelagic vessel and its operating system,this paper discussed the architecture model of open service component architecture model based on the new-type IOT smart service system and its systemic function.In the practical application,the relational representation and management of system service components are grossly complicated while the redundancy and overall relationship between the service components are troublesome to be grasped.Therefore,this paper disserts the dynamic representation method of service components relationship in the system based on the Petri net.Under the effect of this method,the users＇ overall acquisition capability for the service component has been enhanced,which contributes to discover the conflict and redundancy of solving between the service components and provides an intuitive illustration mechanism for the combination configuration of service components.The intelligence of the system and the advantage of SOA are evaluated as well.Meanwhile,the reliability of the method in this paper is proved by means of the experimental simulation.
