Production and consumption balance measuring and calculating method based on case matching

Abstract

The invention provides a production and consumption balance measuring and calculating method based on case matching, wherein the method specifically comprises the steps: obtaining a load expected value and the current working condition data of a to-be-adjusted production device, obtaining the optimal historical working condition data of the corresponding to-be-adjusted production device according to a case matching method, and carrying out the data replacement and dimension reduction processing of the optimal historical working condition data; then inputting a production and consumption data model, obtaining working condition adjustment data and a system production and consumption change value, and performing working condition adjustment on the to-be-adjusted production device; selecting a to-be-compensated production device, obtaining the current working condition data and the production consumption expected value of the production device, obtaining the optimal historical working condition data of the corresponding to-be-compensated production device according to a case matching method, carrying out data replacement and dimension reduction processing on the optimal historical working condition data, and then inputting a load data model to obtain working condition adjustment data; and performing working condition adjustment on the to-be-compensated production device. The measuring and calculating method provided by the invention is accurate in measuring and calculating data, and can automatically generate a production and consumption scheduling scheme of the whole system.

Description

technical field [0001] The invention relates to the technical field of refining and chemical scheduling, in particular to a production-consumption balance calculation method based on case matching. Background technique [0002] In the daily work of refining and chemical enterprises, the processing situation often needs to be adjusted according to the production needs. In this case, the balance of the production and consumption of the entire system, the supply of raw materials for each device, the production of products and the calculation of public works consumption have always been the scheduling and scheduling of difficulty. Nowadays, most domestic enterprises mainly rely on the experience of technicians to make rough estimates of production and consumption. This manual estimation method is difficult to give accurate working conditions of all devices in the entire system under the current situation of changing raw material quality and processing schemes. Variety. Therefo...
