Collaborative model management in departmental computing

Abstract

Today's increasing connectivity between separate entities within an organization has encouraged us to revisit the old promises of departmental computing and propose a: new framework that can expand its potentials. When we view departmental computing from a distributed group decision support systems (DGDSS) perspective, it becomes evident that not only corporate data but also decision models should be an integral part of managerial decision making. In this paper, we present a framework for collaborative model management systems (MMS), which coordinates the changes made to shared decision models in the modelbase so that the net effect of the changes can be systematically propagated across multiple departments by automatically updating the model views. Details of the proposed model change propagation mechanism are discussed along with a realistic departmental computing scenario.
