Abstract

The problem of service distribution has been considered in the fields of task delegation, grid computing and cross-organizational interoperability. This paper proposes a process model transformation technique based on activity aggregation to efficiently distribute services between different actors involved in its execution. We propose a workflow decomposition method based on SPQR fragments and the definition of a service distribution method based on a cost model. This cost model considers not only the transmission of information between activities for data and control scopes but also the cost of activity execution in different domains. Finally we validate our method by providing a tool that introduces the distribution information into the workflow, applying our distribution method in a use case and describing the transformation process to distributed BPEL code.
