Conceptual Modeling Approaches

Abstract

An understanding of information flows and processing functions is essential for any decision-modeling effort. Traditionally, these information flows are described in terms that are specific to particular decision- modeling techniques. However, in the heterogeneous supply chain environment, that results in largely diverse and often incompatible data definitions. Therefore, a more unified approach to representing information flows and their processing functions is required. Conceptual modeling techniques, long-used for information systems development are well-suited for these purposes. Supply chain management is an area where interactions between Decision Sciences and Information Systems Engineering are most profound. Implementation of decisions is not possible without information systems support, and information systems alone without decision-making components are no longer sufficient to maintain a competitive advantage.
