An Enterprise Management Decision Making System based on Possibility Theory

One of the substantial problems in large scale enterprises is lack of the integrity of the operational systems. The information flow among different departments is aiming at integrating data, applications and business processes in an organizational platform. In this research, the authors propose to design a process of decision support system for the integration of three corporate units: purchasing, sales and production. Here, they examine the process in two steps of information flow in each enterprise unit for decision making. While in the second step and according to data from the previous step and due to the uncertainty in the enterprise data it was determined to implement the rules of the system by the possibility theory. Thereby, the events that have effective role in the integrity of organization for each unit are known and enterprise should focus on them to achieve goals. Also, to use actual data of enterprise and to be able to use the results of the work objectively, the authors conducted a case study for implementation purpose.
