基于最大应用模板的服务组合模型

针对面向服务架构中的服务组合问题，提出基于最大应用模板的动态应用定制与服务组合模型，采用最大应用模板描述一类应用的业务逻辑，根据用户输入自动演化生成个性化的应用定制，并以此实现服务组合，采用基于信用的服务质量保证机制和动态重构技术保证组合的服务质量，设计并实现基于该模型的一站式服务平台DACSC，对相关算法进行仿真验证。结果表明该模型可以自动实现应用定制和服务组合，并能降低用户交互次数和服务调度次数，保证组合服务的高可用性。

Service Composition Model Based on Max Application Template

Aiming at the service composition problem in Service-Oriented Architecture（SOA）, a dynamic application customization and service composition model based on max application template is proposed. This model describes application＇s business logic with max application template and according to user＇s input, an application customization is derivated. The user＇s personal requirement is realized composed with services based on application customization. In the process, the Quality of Service（QoS） assurance mechanism and dynamic-reconfiguration are used to improve composition QoS. One-stop service platform called DACSC based on this model is designed and experiments are done. The results show this model can realize application customization and service composition automatically with few interaction and schedule times and enhance composed service＇s ability.
