摘要/Abstract

摘要： 为解决嵌入式系统服务化集成过程中服务的动态组合和重组等应用问题,借鉴化学合成、分子裂解、化学置换、分子复制等化学反应机制,设计了一套化学性服务组合模型。形式化描述了服务组合过程中服务合成、分解、替换、复制等服务行为及其相应的运算演化机制,并在此基础上结合petri网方法给出了服务演化模型,描述了多服务并行和依赖情况下的复合组合过程。最后以指控系统自适应服务组合应用需求为背景,实现了面向任务的服务组合系统,对化学性服务组合模型的应用效果和性能进行了验证和分析。实验结果表明,化学性服务组合模型满足了指控系统自适应服务组合的应用需求,增强了系统的灵活性、可重构性。

关键词: 服务组合,化学反应机制,服务行为模型

Abstract: For working out the problem of service dynamical composition and re-composition in service orient embedded system integration process,a chemical service composition model was proposed．By imitating the manner of chemical synthesis,molecular decomposition,chemical replacement and molecular reproduction in the chemical reactions,service behaviors in the composition process like composition,decomposition,replacement,replication and their operating and evolution mechanisms were formally described．Based on these service behaviors and the petri-net method,the service evolution model was proposed to describe the compound composition process with services reliance and parallel situations．And then,as an illustration for meeting the requirements of service self-adaptive composition in command and control system,an experimental system which is called chemical service composition system (CSCS) was designed and implemented to verify the availability and analyze the performance of the models and algorithms．The results of experiment show that the chemical service composition model satisfies the application request of service self-adaptive composition in command and control system,and effectively enhances the flexibility and reconstitution of embedded systems.

Key words: Service composition,Chemical reaction mechanism,Service behavior model
