The invention linearizes the nonlinear general algebraic model of the discrete manufacturing system, makes the solution simpler and faster, has strong applicability, can effectively reduce the extra energy consumption of the system, and realizes the energy-saving operation of the system.

Description

technical field [0001] The invention belongs to the field of discrete manufacturing, and more specifically relates to a method for saving energy in a discrete manufacturing system based on maximum algebra. Background technique [0002] As people pay more and more attention to the earth's ecological environment, energy conservation, emission reduction and low-carbon development have become a global consensus. Discrete manufacturing, as a large energy consumer, has the characteristics of high energy consumption and low energy efficiency. Therefore, how to reasonably reduce energy consumption and improve energy utilization efficiency has become a major problem facing discrete manufacturing. [0003] Existing research on energy consumption of discrete manufacturing systems focuses on developing new low-energy equipment, researching energy scheduling optimization methods, and establishing energy consumption models of discrete manufacturing systems. Among them, the development of...
