Abstract: With the rapid development of the information technology, process configuration in individualized customization of Software as a Service (SaaS) was discussed. Reconfigurable service process model was introduced to support process configuration of SaaS. Aiming at process model cluster expansion and outdate of presupposed basic business models brought by business process changes, the evolution method for business model was proposed. The new basic process model and update configuration rule set were generated according to execution rates of different model within a valid period and distance between models in process model cluster. With this mothod, the process model cluster needed memory space were reduced and models instantiation efficiency was improved.

Key words: evolving algorithms, process model, software as a service, process configuration, configuration rules
