Decision Models as Software Artifacts - Bridging the Business-Software Gap for Decision Support Systems

In this work we introduce a methodology for integrating the development of decision models with model driven software development approaches. This methodology captures the relationships between service oriented architecture software models and decision models by deriving from a common reference model, the data and conceptual elements of both types of models. Using this reference model and through successive model transformations and refinements, the methodology delivers integrated models and implementation models of software aimed to be more resilient to changes in business models. As all software artifacts are connected through a unique reference model, the collaboration with business partners is enabled at all levels by sharing or reusing existent reference models.
