This work contributed essentially to optimal planning of refinery management. A strategy for solving the decision problem of short—term refinery planning is proposed, that is, to obtain the real time information of unit operations and environmental conditions by means of computer simulation, to dynamically configurate and modify the decision model depending on both simulation and expert reasoning, to make decision analysis and short—term production plan with the aid of expert simulation system. In this paper, a new approach cellad ESDSS was proposed by integrating DSS and expert simulation system . As a case study of ESDSS, a so called RESDSS was constructed, which is composed of seven subsystems, namely: data base subsystem, model base subsystem, method base subsystem, knowledge base subsystem, experiment base subsystem, human computer interaction subsystem, and expert simulation executing subsystem. The main results and contributions of this work are as follows:(1) A novel approach of DSS named ESDSS was proposed, which integrates DSS and ESS.
