The invention relates to the technical field of
petroleum refining, and provides a refining product production scheme determination method, device and equipment and a medium. Obtaining the input-output proportion of products of various grades produced by the production device, the public
engineering consumption proportion of unit products, the input-output proportion of transition materials produced in the grade product switching process, and the public
engineering consumption proportion of unit transition materials; based on the proportion, constructing an input-output
material balance equation and a public
engineering consumption equation for producing products of various grades by the production device, and a
material balance equation and a public engineering consumption equation for producing transition materials in the grade product switching process; constructing a target function with maximized total benefits; constructing a full-connection network of the switching paths of the products of each
trademark, and constructing an integer variable constraint equation and a
continuous variable constraint equation based on the full-connection network of the switching paths of the products of each
trademark according to the demand types of the products of each
trademark and the demand quantity of the products of each trademark; under the current market demand and market price conditions of products of various brands, the objective function and the equation are solved simultaneously, the optimal production scheme of the production device in the switching production process of the products of various brands and the number of the products of various brands are obtained, the
optimization problem of the switching sequence of the products of the production operation brands of the
petroleum refining device can be solved, and the production efficiency is improved. The overall benefit is improved.
