Abstract: In order to implement distributed business process management and lower heterogeneous process integration cost, web-services-based and agent-based business process management architecture with three-tiers was proposed, and a software system design and implementation process was provided based on the architecture. In this architecture, Data Level provided relevant information and supports to the definition, constitution and execution of business process, Collaborative Application Level was the core of the system, including business process engine module and four kinds of agents responsible for Web services search, selection and allocation, and Interface Level provided collaborative process management between system and service providers. Furthermore, in order to reduce the interactions and data exchanges among service providers and user systems, a Web services selection algorithm based on service providers location was put forward which provided better solution to time-sensitive distributed business process management.

Key words: business process management, process modelling, Web services selection
