Model integration that allows multiple models to work together for solving a sophisticated problem has been an important research issue in the management of decision models. The recent development of the service-oriented architecture (SOA) has provided an opportunity to apply this new technology to support model integration. This is particularly critical when more and more models are delivered as web services. A web-services-based approach to model management is useful in providing effective decision support.
In the past, existing literature has adopted the approach that treated a model as a service. Model integration can be thought of as a composition of web services. In the composition process, proper components and their relationships must be properly identified. This requires accurate model definition and reasoning.
In the research, we propose a semantic-based approach for developing such as system. The approach uses DAML-S to describe the capability of a service. Then the system can discover proper services for a particular requirement by using semantic matching on these DAML-S documents. When suitable web services are found, the system uses BPEL4WS to composite them together. The resulting composite web service can be applied to decision support. A prototype that demonstrates the feasibility of the proposed approach is implemented in Java.
