Ecological-Economic Modelleing to Maintain Maxiumum Allowable Discharge of Substanses into the Water Body

Abstract

Today administrative mechanisms of ecological management are primary in Russia. Their inefficiency is defined by absence of advancing influence and the due control. These mechanisms, as a rule, start to operate when negative influence is already made and harm to the environment is done. The work urgency is caused by the sharpness of the water legislation and regulation problems in Russia, as this sphere is the crossroads of all industrial, agricultural interests and also providing good life conditions for the population. The urgency of ecological-economic modelling is caused by rapid development of ecological management systems in the last years. That is stimulated by the aspiration of market participants to raise management efficiency of the enterprises, to lower power and resources consumption, to raise the quality of goods and services, to create more comfortable working conditions, to provide safety of the personnel and, as a result, to improve the reputation and to raise their
competitive advantages.

The purpose of the work is to draw up and to deicide a problem of ecological-economic optimization within the limits of linear programming for a “water user – water body” system. Such a linear programming problem is similar to the model of investment projects choice. The problem’s solution is based on searching the best, from the economic point of view, sewage treat system to maintain maximum allowable discharge of substances into the water body.
