Abstract
The development of a generalized strategy for modeling and integration of an overall system, for detailed economic analysis of industrial systems, is described. Economic analysis of a system establishes the economic analysis of streams and processes with respect to the current system operation, network configuration, and market situation. An overall integration is developed to capture the impacts of real plant operations and the effects of network interactions in the detailed economic analysis of complex systems. The approach for economic analysis of a system is simple and provides a transparent and complete set of economic values for all basic components and correlates these values with the overall system economic margin.
