Layout optimization method and system based on SKU combination

The invention discloses a layout optimization method based on an SKU combination, and the method comprises the steps: constructing an SKU database and a warehouse exit position database, initializing the storage parameters of a stored material in the SKU database, and enabling the storage parameters to comprise a material ID name, a material size and a material weight; the SKU database sets carrying difficulty coefficients for the corresponding materials according to the storage parameters; the warehouse outlet position database stores coordinates and direction information of all warehouse material outlets, analyzing the material demand request to obtain a requester of the material demand and demand parameters of the required material, and combining the required material with the required material according to a preset material combination strategy corresponding to the requester of the material demand. Calculating an optimal SKU combination required by each material demand; and performing statistics on the ma
