【摘要】 提出了基于网格的动态服务组合模型与算法.首先检查需求语义形成服务的功能候选图;然后应用服务选择算法形成优化组合模型;最终选择理想的服务组合,并用实验进行模拟验证.结果表明,提出的模型和算法为用户提供了满意的服务功能.服务组合可聚合独立的、可重用组件,提供面向用户的服务.更多还原

【Abstract】 A dynamic service composition model and select algorithm based on grid was presented.First,it checks requesters′ semantic in order to form service candidate service graph.Second,it designs service selecting algorithms for optimizing the model.Third,it selects an optimum composition.We conducted experiments to simulate and evaluate our approach.Service composition can get together independent package,provide service faced to users.更多还原
