Method, medium and device for establishing difference and linear MILP model for complex linear diffusion component

The invention provides a method, medium and device for establishing a difference and linear MILP model for a complex linear diffusion component, and the method comprises the steps: depicting the difference/linear branch number of the complex linear diffusion component through a linear inequality, and enabling the difference/linear branch number to serve as a constraint condition 1 of a difference/linear model; a linear inequality is used to describe a forward XOR/branch relation of the complex linear diffusion component, namely, an XOR/branch relation from input to output is used as a constraint condition 2 of a difference/linear model; depicting a reverse XOR/branch relation of the complex linear diffusion component by using a linear inequality, namely, an XOR/branch relation from output to input, and taking the reverse XOR/branch relation as a constraint condition 3 of a difference/linear model; and completing the modeling of the differential/linear MILP model according to the three constraint conditions.
