摘要: 企业信息系统体系结构(ISA)是一个战略、业务、应用以及IT基础设施层的关联模型。ISA的性能分析是在考虑各层关系的同时,分析IT相关资源的性能。针对ISA层次化的特点,该文建立一个面向服务的ISA框架,利用广义Petri网并结合排队论来定量分析ISA的性能;并用案例说明了性能分析的过程。

关键词: 信息系统体系结构, 面向服务, 性能分析

Abstract: Enterprise Information System Architecture(ISA) contains descriptions of strategic, business, application, IT infrastructure and inter-relations. ISA’s performance analysis is concerned with layer’s relations and focuses on analyzing performance of IT-related resources. Considering hierarchy of ISA, a service-oriented framework is constructed which facilitates analysis performance of ISA based on theories of petri-net and queuing network. A case study is given.

Key words: Information System Architecture(ISA), service-oriented, performance analysis
