Calculation of the surface water pollution index in the evaluation of environmental component of product life cycle

<p>The assessment feasibility of the combined effect of the product life cycle on the environment is grounded. As an example, the pollution of surface waters at the production stage is considered in the article. A mechanism of ranking indicators of surface water pollution according to their importance is proposed. An algorithm for checking the consistency of the statistical expert judgment in determining weight coefficient for the indicators of pollution, based on the use of the concordance coefficient, is given
