Abstract

The present invention provides an optimal scheduling method of parallel batch processing machines. According to the characteristics of the batch scheduling problem, a probability model is established based on group batches of the workpieces; a corresponding individual sampling and probability update method is designed; the population generation of the compact genetic algorithm and the probability update mechanism are improved; and a novel intelligent algorithm for solving the batch scheduling problem is provided. On the premise of satisfying the batch switching-on production requirement of batch processing machines, the production is accelerated, and the production cycle is shortened. Through flexible parameter setting, different batch scheduling problems may be solved, different conditions, such as one machine / a plurality of machines, same arrival time / different arrival time, same size of workpieces and different sizes of workpieces, and limited capacity of the batch processing machines / unlimited capacity of the batch processing machines, are able to be flexibly combined, and the generality of the optimal scheduling method of parallel batch processing machines is high.

Description

technical field

[0001] The invention belongs to the field of production planning and scheduling, and specifically relates to an optimal scheduling method for parallel batch processing equipment aimed at the scheduling and scheduling of curing processes in a semiconductor packaging and testing production line. Background technique

[0002] The level of production management determines the direct operating benefits of an enterprise, which mainly includes three stages: production planning, production scheduling and production control. Among them, production scheduling is a key link in the field of production management. It undertakes the rough arrangement of production planning and at the same time gives more detailed production arrangements for the control of the production workshop. With the improvement of the degree of automation and information in the manufacturing industry, production scheduling has gradually changed from manual scheduling to automatic scheduling. General...
