| 摘 要： | 在海量服务环境下,如何快速灵活地选择出满足用户需求的服务组合,已经成为亟待解决的问题.该文借助生态系统的运作模式,首先把服务进行层次划分,进而根据用户的服务流程需求,提出一种两层服务选择的智能优化方法,并建立两层目标规划模型.模型中第一层为服务流程的每个服务结点选择一个服务中心,第二层为每个结点在第一层指定的服务中心内...

| Abstract: | The service-oriented methodology is creating more and more services registered in the current enterprise environment.These many services make finding a set of services to meet the user's needs very difficult.Here,the services are first divided into service populations,and service centers.Then,the user demands for the service process are put into a two-layer intelligent optimization service selection method as a two-layer goal programming model.The first layer is used to find the satisfied service centers an... |
