企业信息系统集成中复杂业务流程优化方法研究

摘要

InSOA-basedenterpriseinformationsystemintegration,theperformanceofthecomplexbusinessprocessusuallyaffectsthe integration of entire system,and becomes a key factor of the system integration in regard to its success or failure.We propose a data flow analysis-based complex business process optimisation approach.This approach gives formal description on the business process described in BPEL,collects data flow information by establishing data flow equations,and then builds the data flow optimisation algorithm to optimise the data transmission in business process.Experimental results show that along with the increases of integrating data amount and concurrent visits amount,the proposed approach can optimise data transmission in business process effectively and reduce the average response time of the process by 30% to 50%.%在基于SOA体系架构的企业信息系统集成中，复杂业务流程的性能问题往往影响整个系统的集成，会成为系统集成成败的关键因素。提出一种基于数据流分析的复杂业务流程数据优化方法。该方法将采用BPEL描述的业务流程进行形式化描述，通过建立数据流方程收集数据流信息，然后建立数据流优化算法优化业务流程中的数据传输。实验结果表明，随着集成数据量和并发访问量的提高，该方法可有效优化业务流程中的数据传递，降低30％至50％的流程平均响应时间。
