Multi-criteria analysis of resource saving and energy efficiency in the technogenic waste processing system of the oil and gas industry
The paper proposes a new approach to multi-criteria analysis of resource and energy saving in the system of processing industrial waste of oil and gas enterprises based on the Data Envelopment Analysis (DEA) method. The DEA method is being extended by the authors to a completely new subject area of extremely important engineering applications related to the problems of processing oil and oily waste. The basis of the algorithm for analyzing objects of the wastes processing system considered in the article is a new methodology for sequentially solving interrelated problems of multi-factorial comparison of objects according to heterogeneous quality criteria, which differ in new formulations of related problems of mathematical programming. The developed algorithm for multi-criteria analysis of resource and energy saving in the processing system allows: collecting, classifying and processing information about the objects of the system; assessment and analysis of the resource value of waste in storage, which determines the degree of suitability of waste for use as material resources in processing technologies associated with their recycling and recovery; assessment and analysis of the resource potential of storage facilities and technologies, which determines the efficiency of the secondary use of industrial waste, taking into account their resource value; evaluation and analysis of the resource and energy saving in the system in general. The partial and generalized indicators of the efficiency of the waste processing system obtained as a result of solving interrelated problems of mathematical programming are analyzed in the decision support system and make it possible to form local control actions on the system or to justify the strategies for managing the waste processing system. The proposed approach can in the future receive multiple applications in the oil-bearing regions of the Russian Federation, where the growth in the formation of the technogenic waste has serious and often irreversible environmental consequences.
