基于设计结构矩阵的服务关联规划

Service Correlation Planning Based on Design Structure Matrix

设计结构矩阵作为一种数学工具,能够有效描述复杂系统中元素之间的信息传递关联关系,并通过相关原则和算法减少系统内部迭代关系,缩短元素之间信息传递链长度,达到优化系统结构,提高系统效率的目的。服务关联是服务组合过程中的重要因素,对服务组合效率具有重要意义。为此,将设计结构矩阵应用于服务关联关系规划,通过完成实例的设计结构矩阵初始化来表达子服务间信息传递关联,并通过矩阵重构原则及相关算法完成系统设计结构矩阵重构,以缩短子服务信息传递链长度,减少服务之间的迭代关联,优化组合服务内部结构,提高服务组合效率。

Design Structure Matrix（DSM）,as a kind of mathematical tool,can precisely describe the correlation among elements of a complex system,effectively reduce the length of information transfer chains,simplify the structure and increase efficiency of the system with the help of relevant principles and algorithms. Service correlation is a key factor of service composition,so it is quite crucial for the efficiency of service composition. It applies DSM to service correlation planning,in the example,it describes the relationships among sub-services by constructing the original DSM,and by using DSM reconstruction principles and relevant algorithms,this method effectively reduces the length of service information transfer chains,decreases iterations among sub-services,such that the internal structure of the composite service is optimized and the efficiency of service composition is increased effectively.
