Abstract

The present invention discloses a simulation-based logistics distribution system and distribution method. The system comprises an MES subsystem, an APS subsystem, a logistics distribution subsystem and a simulation optimization subsystem. The MES subsystem is used to collect and output order data, overall basic data and on-site real-time data, and output a dispatch plan; the APS subsystem is usedto establish a scheduling model based on the overall basic data, and determine production scheduling plan according to the on-site real-time data, the order data and the scheduling model; the logistics distribution subsystem is used to, according to the distribution basic data and the production scheduling plan, determine the material distribution plan under different distribution cycles with different stocking intervals; and the simulation optimization subsystem is used to carry out production modeling based on the overall basic data to obtain the simulation model, output production evaluation values of the material distribution plan under different distribution cycles with different stocking intervals, and take the material distribution plan with the best production evaluation value as the final material distribution plan to be output, wherein the logistics distribution plan satisfies the production without shortage.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to a simulation-based logistics distribution system and distribution method. Background technique [0002] In manufacturing enterprises, due to the consumption of materials in the normal production process, the amount of materials on the line is reduced. When the inventory on the line reaches a certain minimum value, it is impossible to supply materials in time, resulting in a shortage of materials in the production line and resulting in shutdowns, resulting in losses due to failure to meet orders. [0003] At present, the logistics system needs to meet the requirements of delivering the most appropriate number of parts to each station at the most appropriate time. If there are N stations that need to replenish parts at the same time, what rules should be followed in the order of distribution and the various assembly parts received? The quantity has bee...
