Dynamic models of environmental data envelopmenr analysis with stock and flow variables

The paper devoted to the elaboration of methodological approach to the solution of dynamic problems of Environmental Data Envelopment Analysis for production facilities, whose activities are characterized by a set of variables of two different types - stock variables and flow variables. The limitations that are additionally imposed on the Production Possibility Set are studied. A task is set for assessing the comparative effectiveness of regional systems of environmental management that operate at a certain time interval. A computational example is given for assessing the comparative effectiveness of environmental management systems in the regions of the Central Federal District in the period from 2010 to 2014. The possibilities of using the developed method in practice are discussed.
