Technological Model of Compound Systems of Water Management at Industrial Enterprises and Complexes

Summary

A technological model has been developed; a mathematical formulation of compound systems of water management at industrial enterprises and complexes has been proposed. The model represents systems of equations reflecting a non-stationary and stationary condition of the system operation. The model is used by the ECO-PROJECT scientific-design firm during the study and development of principal decisions of step-by-step reconstruction of the enterprises’ water management systems and in the course of designing. It can be also useful for the management, audit and ecological control of water management of industrial enterprises.
