【摘要】 对如何在业务层面即时组合服务,按需创建个性化应用进行了研究,提出了一种适合业务用户使用的大粒度服务组合方法———TROLL方法.该方法利用服务组合模板并结合多约束下的参数进行求解,以一种大粒度、可重用的方式组合业务服务,从而提高服务组合的自动化程度和抽象层次.该文重点介绍了时序约束下如何利用组合模板进行业务级的服务组合.实验结果表明 TROLL方法降低了用户参与服务组合的难度,在业务级面向服务应用的构造上效率更高.更多还原

【Abstract】 This paper presents an approach, called TROLL, to larger granularity service composition for business users, which is based on prefabricated and modifiable templates and constraint solving. With TROLL, business users can construct applications just like assembling hardware by composing larger granularity and reusable modules. This paper introduces how to use composition template under temporal constraint in detail. The experimental results show that TROLL approach facilitates business user involved service composition and improve the efficiency of service oriented application construction on business level.更多还原
