Abstract

This paper presents applications of the decision support system dictum. The developed software package dictum represents a sophisticated, user-friendly computerized system for the analysis and synthesis of large-scale industrial process systems, such as the chemical and related industries. The generation, evaluation and optimization of alternative strategies of the development of technological systems are closely connected with computer-aided decision making. Important decision-making problems with respect to energy saving and environmental impact are characterized by the following features: (i) analysis and evaluation of the status quo, formation of optimal control strategies and revamp policies; (ii) synthesis of feasible development strategies (long-term planning alternatives including resources requirements and energy supply, product demand) and environmental impact analysis. Some of the problems under study are the optimal combination of conversion processes in refinery plants, the improvement of alternatives for the supply of synthesis gas in an ammonia plant and the evaluation of C 2-chemistry subsystems to produce acetylene, acetaldehyde and acetic acid.
