Process instance set evolution and management method based on configurable process model

The invention provides a process instance set evolution and management method based on a configurable process model, and belongs to the fields of service processes and information technology. A similar process instance set which describes identical services serves as input, process instances are merged and generate the configurable process model automatically, and the model is used to describe and manage the process instance set in a unified way. When the process instance set changes, namely a process entity is newly added, deleted or modified, automatic evolution occurs in the corresponding configurable process model automatically to adapt to change of the process instance set. The method of the invention is visual, simple and effective, generation of the configurable process model is characterized by one-step model merging and support for construction of configuration rules, the unified configurable process model is established, so that the problems including that similar process entities existing in a proc
