Embodiment Construction

[0034] In this embodiment, a scheduling method for the automobile chassis blanking workshop based on material distribution is to model the scheduling problem of the automobile chassis blanking workshop with limited material distribution capacity and a line side warehouse next to the processing equipment, and then improve the genetic Solve the algorithm to obtain the optimal scheduling plan of the automobile chassis blanking workshop, and optimize the placement of materials in the online side warehouse according to the scheduling plan, so as to shorten the waiting time of processing equipment, improve production efficiency, and achieve continuous and stable production. . Specifically, proceed as follows:

[0035] Step 1. Data preprocessing, counting the types of materials required, and calculating the processing time of each material according to the type, number and processing time of the workpieces to be processed for each material. The processing time of the materials is cal...

Abstract

The invention discloses a material delivery-based automobile chassis blanking workshop scheduling method. According to the method, modeling is carried out in allusion to scheduling problems of automobile chassis blanking workshops which are limited in material delivery ability and arrange storage areas besides machining equipment, and solution is carried out through an improved genetic algorithm so as to obtain optimal scheduling schemes of the automobile chassis blanking workshops; and meanwhile, placing positions of materials in the storage areas are optimized according to the scheduling schemes, so that the waiting time of the machining equipment is shortened, the production efficiency is improved and continuous and stable production is realized.

Description

technical field [0001] The invention relates to the field of workshop scheduling control, in particular to a material distribution-based workshop scheduling method for unloading automobile chassis. Background technique [0002] The workshop scheduling problem refers to the rational allocation of production resources under certain conditions to meet certain production goals. Since the materials consumed in the automobile chassis blanking workshop have many types, take up a lot of space, and the crane is not easy to grab, and the crane is used as a material distribution equipment, it may appear multi-tasking, which affects the orderly and compact processing tasks. . The data shows that 85% of the time in the actual production of workpieces is wasted in waiting, handling and other processes. Therefore, considering the material distribution capacity of the crane and the storage location of the material in the online side warehouse when scheduling the automobile chassis blankin...
