旅游信息服务组合的Petri网建模及其实现

Modeling on Petri Net and its Implementation for Travel Information Service Composition

目前,用户查找旅游相关信息还缺乏一个有效的自动化信息服务整合工具.本文根据用户提供的出行时间、目的地、出行方法等信息,利用Petri网建立了一个旅游信息服务组合模型.该模型较全面地刻画了旅游相关信息的Web服务组合流程.原型系统的实现直观地说明了该模型是有效的.

At present,users lack of an effective automation tools to integrate information services when searching travel-related information.In this paper,a tourism information service composition model using Petri Net is established based on some information such as user travel time,destination,methods and so on. The model depicts a more comprehensive web-service combined process which is related with tourism.Finally,Implementation of the prototype system directly illustrates the model is valid.
