Workshop production scheduling method and system based on resource constraint, terminal and medium

Abstract

The invention discloses a workshop production scheduling method and system based on resource constraint, a terminal and a medium, and relates to the technical field of automatic manufacturing, and the technical scheme is characterized in that the method comprises the steps: obtaining the machining process and real-time resource information of a target workpiece; performing executable sequence adjustment on the machining procedures of the target workpiece to obtain an executable procedure set; when the real-time resource information of the processing workshop is in an abnormal state, matching an executable process from the executable process set to serve as an alternative process; and according to the sequence adjusting times, the replacement cost and the production yield, all the replacement procedures are comprehensively analyzed, and the replacement procedure with the highest priority is selected to replace the current machining procedure to continue machining treatment. According to the method, part of the working procedures in the machining working procedures are replaced and adjusted, so that the replaceable and complete executable working procedures are generated in advance, when the resources are abnormal, the optimal replacement working procedure is selected for rapid replacement, rapid updating of workshop production scheduling is achieved, and the complexity of updating of the production scheduling machining working procedures is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automated manufacturing, and more particularly, to a workshop scheduling method, system, terminal and medium based on resource constraints. Background technique [0002] The purpose of production planning scheduling is to generate a detailed short-term production plan for one or more workshops. The production scheduling plan specifies the processing start time and end time of each order within the planning scope on the required resources, that is, it points out the processing procedure of the order on the given resource, which is essentially a complex combinatorial optimization problem. [0003] With the continuous development of intelligent technology, the current production line scheduling applies various algorithms for intelligent production scheduling. In the prior art, part of the production line scheduling is to optimize the arrangement of all the processing steps of a single target workpiece, or t...

Problems solved by technology

In the prior art, part of the production line scheduling of the processing line is to optimize the arrangement of all the processing procedures of a single target workpiece, or to prioritize the different target workpieces at the same time considering the current resource constraints. For example, the Chinese patent with the notification number CN110738413A discloses a multi-constraint production scheduling calculation method and device for an automated aviation parts processing production line, which mainly prioritizes each processing procedure based on resource constraints. Calculation, and then simulation analysis to obtain the calculation results of production scheduling, so as to analyze the production scheduling plan in advance; however, there is no real-time and dynamic update of the production scheduling plan based on processing resources, resulting in the failure to achieve the best output and weak emergency response capabilities

In addition, some processing production lines are scheduled through real-time collection of resource information of processing workshops, such as the Chinese patent with the announcement number CN109598416B, which discloses a dynamic production scheduling system and production scheduling method for composite material workshops. Through dynamic analysis Processing scheduling analysis, considering the relevant information optimization analysis of the entire processing process to obtain the current optimal scheduling plan, although it is time-sensitive, but because of the large amount of design information and real-time comprehensive updates, the required network resources and investment more expensive
