Embodiment 1
[0093] This embodiment provides an assembly line material delivery method based on the line-side integrated supermarket. The line-side integrated supermarket stores materials. The assembly line material delivery method includes determining the material delivery scheduling plan, and the material delivery worker stores the line-side integrated supermarket according to the material delivery scheduling plan. The materials are distributed to the bins in the material assembly station, and the determination of the material distribution scheduling scheme includes the following steps:
[0094] Construct the objective function of minimizing the hiring cost of material delivery workers and the cost of material delivery, and use the improved harmony search algorithm to determine the material distribution scheduling plan, which includes the responsible station of the material delivery worker, the time of each replenishment behavior, and stations and the amount of material delivered for each...

The invention relates to an assembly line material distribution method and system based on a line-side integrated supermarket, wherein materials are stored in the online integrated supermarket. The assembly line material distribution method comprises the following steps: determining a material distribution scheduling scheme; and enabling the feeder to distribute the materials stored in the line-side integrated supermarket to a material box in a material assembly station according to the material distribution scheduling scheme. The method for determining the material distribution scheduling scheme comprises the following steps: constructing a target function for minimizing the employment cost of a feeding worker and the feeding cost; and determining a material distribution scheduling scheme by adopting an improved harmony search algorithm, wherein the material distribution scheduling scheme comprises the responsible station of a feeder, the time of each material supplementing behavior, the station and the material quantity distributed for each station. Compared with the prior art, the invention has the advantages of high efficiency, reliability and the like while minimization of feeding worker employment cost and feeding cost is guaranteed.
Description
technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a material distribution method and system for an assembly line based on a line-side integrated supermarket. Background technique [0002] Mixed-model Assembly lines (MMAL) is a mass production mode that realizes simultaneous production and assembly of multiple models of vehicles. It not only retains the advantages of mass production, but also effectively controls manufacturing costs through reasonable production planning and scheduling strategies. At the same time, respond to changes in market demand, avoid inventory backlogs, and improve corporate competitiveness. However, as automakers offer customers an increased variety and number of vehicle options, they often face the challenge of balancing production schedules for millions of vehicle models. In addition, the structure of a car is usually very complex, which requires hundreds of thousands of parts to be a...
