Then, after reviewing former research, we combine the solution of industry and academy, a new architecture called BWADM based on the researches above is proposed, it is a distributed data mining system based on Web services and Agent in Electronic commerce environment. Web service composition rules and execution of Web service composition are discussed. These modules are introduced detailedly in Electronic commerce environment; there are algorithm management module, control center module, algorithm database module and model representation module. Lastly, a prototype system of distributed data mining is given in Electronic commerce.

在此基础上，结合业界和学术界对Web服务和移动Agent的研究成果，将Web服务和Agent最新技术引入了电子商务环境中分布式数据挖掘，提出了电子商务环境下基于Web服务和移动Agent技术的数据挖掘架构BWADM，并论述了组合服务规范与组合服务的执行，具体阐述了此架构的数据预处理组件、算法管理组件、控制中心组件、算法库组件和模型表示组件。

On global optimal algorithms, a heuristic 0-1 Integer Liner Programming algorithm is achieved, which combines heuristic enumeration method and revised simplex method. Simulation experiments show that the degree and optimization efficiency in our algorithm is obviously improved compared with the MATLAB 7 bintprog function that is a 0-1 integer programming algorithm. Moreover our algorithm isn\'t relevant to the scale changes of Web services composition and candidate service sets, thus it is applicable for the scenes that the scales of Web services composition changed dynamically. But for Web services composition with service alliance, the algorithm is unable because the non-linear global optimal model of the fitness function and QoS constraints can\'t be expressed in linear mode.

在全局优化算法研究上，基于启发式0-1整线性规划算法结合了修正单纯形法和启发式枚举法，仿真实验表明该算法与MATLAB 7的0-1整数规划方法比较，在优化程度及优化效率上得到了显著改进，并且对服务组合和候选服务集合的规模变化没有明显的相关性，因而该算法可用于服务组合规模动态变化的场景，但该算法不能应用于存在服务联盟的非线性全局优化模型。
