| 摘 要： | 现有的Web服务复合一般都采用静态绑定的方法，无法实现服务的动态绑定和整个服务流程的动态性能优化。为此，提出了一种基于约束Agent进行面向性能优化的动态服务复合方案；引入了约束以表达服务复合中的性能要求；设计了一种基于约束的信念一希望一意图智能主体；实现了基于约束的协商算法以实现服务的优化选择；介绍了一个实例和系统实现。

| Abstract: | The current composition of Web services usually employs a static binding approach so that services can't be dynamically integrated and the overall service process cannot be optimized. A dynamical service composition model based on constraint agent was proposed to optimize the performance of the service process. Constraint was introduced to represent performance requirements in service composition. An Belief-Desire-Intention (BDI) agent based on the constraints was designed, and a negotiation algorithm was developed to support optimized service selection. The case study and an introduction to the system implementation were also given. |
