Application of an ontological approach to the problems of energy consumption data exchange

The article describes the technical concept of organizing data exchange between a specialized settlement center that carries out billing of consumed heat energy, and an energy sales company that supplies heat energy to industrial enterprises, government agencies and the population. The article describes the features of the technical problem of data exchange, which determine the parameters of mathematical models for calculating the volumes and costs of consumed energy resources, and then reviews approaches to solving this class of problems. To solve the technical problem, the features of the data preparation stage for the initial data exchange were formalized and schemes for organizing a regular data flow based on an ontological data model were proposed. The originality of the proposed approach was expressed in the definition of classes and their properties for concepts reflecting sets of information about the parameters of energy supply facilities, parameters for calculating volumes, prices and costs of energy resources, which made it possible, using an ontology editor, to form graphically formalized semantics, which became the basis for the formation of rules data processing for information exchange. The concepts of the ontological model were related to each other by sets of classified predicates, the use of which was illustrated by examples of descriptive logic queries. The implemented data exchange process based on the ontological model is illustrated with a data flow diagram. The ontological approach to solving the described problem made it possible to organize an end-to-end connection between the formalized reflection of the calculation models required for billing and the exchange data model, which made it possible to balance and comply with management and information technology requirements for this procedure.
