This paper introduces the ideas behind BPML, the business process modelling language published by BPMI. BPML provides a process-centric (as opposed to a datacentric) metalanguage and execution model for business systems. It is underpinned by a strong mathematical foundation, the pi-calculus. The current paper is derived from supplementary appendices to a book which describes a ‘third wave’ approach to business process management [Business Process Management: The Third Wave, 2003]. The aim is to model business processes directly in an executable form, so that the mobility and mutability inherent in business behaviour is reflected and supported in the corresponding IT systems, erasing the present IT-business divide. 相似文献

为了更有效地保证跨组织业务流程模型的正确性和合理性,应用Pi演算提出了一种基于状态的角色行为的验证方法。基于Pi演算提出了跨组织业务协作中的角色模型,设计了角色描述表,以清晰、直观地描述角色的权利、职责和义务,进而应用Pi演算验证工具MWB(移动工作平台)的check和step命令提出了单角色验证方法,并在此基础上从业务对象状态和业务操作角度提出了多角色验证方法。实现了角色行为的验证,并为跨组织业务流程的可达性、一致性和死锁等分析奠定基础。 相似文献

Web服务组合的目的是实现单一服务无法满足的复杂功能,而保证组合的正确性以实现服务增值是十分必要,因此组合之后的正确性验证是Web服务组合的一个重要研究方向。从Web服务交互行为方面描述多Web服务组合,在提出行为兼容性的相关理论的基础上,给出基于Pi演算的多Web服务组合行为兼容性的自动化验证算法,通过将多Web服务组合自动转化为Pi演算中的组合进程,实现多Web服务组合的自动化验证。 相似文献

This paper investigates the use of the so-called up to techniques for bisimulation in the framework of verification. We first
introduce a method to exploit these techniques, that originate in theoretical works, in the applied context of verification.
We then apply it on the π-calculus, in order to design an up to bisimulation verification algorithm for π-calculus terms.
The outcome of such an effort is evaluated on two examples that were run on a prototype implementation.

Web服务的相容性分析是为了保证多个Web服务之间的正确交互。基于Pi-演算对Web服务的相容性进行了形式化的分析,给出了二个Web服务之间相容性的两个形式化定义。同时定义了二个Web服务进程之间的投影操作,在此基础上给出了多个Web服务之间相容性的形式化定义。 相似文献
