Automatic production line modeling and layout planning method and system

Abstract

The invention discloses an automatic production line modeling and layout planning method and system, and the method comprises the steps: (1) carrying out the data feature extraction of an actual production line through a training network, and employing an adjacent gradient algorithm in the weight updating of the training network; (2) constructing a TCPN model corresponding to a production functionby using a Petri network, reconstructing an actual production line, and connecting the TCPN models of the production functions to obtain an OOTCPN model of the production line; (3) carrying out layout planning by using an adaptive genetic algorithm based on the OOTCPN model, selecting individuals with high fitness to carry out iteration to approach an optimal solution, and providing a planning scheme for process layout and logistics layout of a production line. Modeling simulation is carried out on an actual production line, corresponding layout planning suggestions are given, the productionprocess is simulated, analyzed and evaluated through the model, and modularization and standardization of the automatic production line are better guided.

Description

technical field [0001] The invention belongs to the field of automated production lines, and in particular relates to a modeling and layout planning method and system for an automated production line. Background technique [0002] With the introduction of concepts such as Industry 4.0 and Made in China 2025, the transformation and upgrading of the manufacturing industry has attracted more and more attention from the society, especially the manufacturing of small household appliances as a typical representative. There are many models of small household appliances, the product iteration speed is fast, the production schedule adjustment is relatively frequent, and with the emergence of problems such as product quality that needs to be improved urgently, labor costs increase, and market demand is constantly trending towards individualization, enterprises have changed from the past with large batches and small batches. The traditional production methods of small household applian...
