Architecture-level business services are identi- fied based on business processes; and likewise, in service- oriented product lines, identifying the domain architecture- level business services and their variability is preferred to be based on business processes and their variability. Identifica- tion of business services for a product line satisfying a set of given design metrics （such as cohesion and coupling） is ex- tremely difficult for a domain architect, since there are many product configurations for which the services must be proper at the same time. This means that the identified services must have proper values for n metrics in m different configura- tions at the same time. The problem becomes more serious when there are high degrees of variability and complexity embedded in the business processes that are the basis for ser- vice identification. We contribute to solve the multi-objective optimization problem of identifying business services for a product line by partitioning the graph of a business process variability model utilizing Non-dominated Sorting Genetic Algorithm-II. The service specification is achieved based on the results of the partitioning. The variability of the services is then determined in terms of mandatory and optional services as well as variability relationships, which are all represented in a Service Variability Model. The method was empirically evaluated through experimentation, and showed proper lev- els of reusability and variability. Furthermore, the resulting models were fully consistent.
