摘要
Web服务是微软和IBM公司为能够解决当前的信息的整合而提出的,是一种部署在Web上、面向Internet的、基于XML的对象/组件技术;其目标是能够自动和统一地封装服务信息、服务行为、数据表示以及商务流程。商务流程的建立对于Web服务是至关重要的,因为Web服务之间的信息协调是以商务流程为基础的。因此IBM为解决该问题,提出了Web服务流程语言(webservicesflowlanguage,WSFL)。但是IBM提出的WSFL没有能够从并发协调的角度来阐述商务流程的建模方法,所以提出利用Petri网为模型描述工具,用于描述与分析商务流程模型,同时给出Petri网与WSFL之间的转换算法,并以实例证明了该模型用于商务流程的建模方法是切实可行的。
Web services presented for solving the current integration of the information system by Microsoft and IBM are the techniques of objects/components based on XML and deployed in web and internet, which aims are able to encapsulate the service information, service behavior, data representation and business flow based on uniform standard, wherever web service are applied to. It is most important that the business flow model is constructed, because the information cooperation of web services is based on it. Consequently, IBM submits the web services flow language （WSFL）. The approach of building business flow model is not specified from the view of the concurrent. So the approach of business flow models is brought forward using Petri nets, and then the conversion algorithm from Petri nets to WSFL is proposed. In the end the example proves that the method is feasible
