A Multi-Criteria Web Services Composition Problem

With its prevalence in enterprise applications integration, the service-oriented approach has been studied in various ways. The popularity, however, results in a number of different standards and implementations. The approach needs agreed-upon definitions and assumptions. To this end, the paper presents a multi-criteria service composition problem and positions to state service engineering functions associated with the problem in a formal form. The paper also introduces an information compatibility concept to measure the degree of interoperable data exchanges between services.
