Production and transportation cooperative dispatching method and system based on improved harmony search

Abstract

The invention relates to a production and transportation cooperative scheduling method and a production and transportation cooperative scheduling system based on improved harmony search. The production and transportation cooperative dispatching method comprises the steps of: 1, performing group batching on work pieces; 2, setting algorithm parameters; 3, generating an initial harmony library; 4, calculating an adaption degree value; 5, acquiring a negative ideal solution of the harmony library; 6, generating a new harmony; 7, performing harmony library searching operation on the new harmony, and updating the new harmony; 8, comparing the new harmony with the negative ideal solution, if the new harmony is superior to the negative ideal solution, substituting the negative ideal solution and updating the harmony library; 9, updating a global optimal solution; 10, and judging whether a termination condition is satisfied, if so, outputting the global optimal solution, otherwise, returning to the step 4. The production and transportation cooperative scheduling method and the production and transportation cooperative scheduling system can realize the optimization of overall efficiency of the supply chain, thereby reducing cost of the supply chain, and enhancing customer satisfaction level.

Description

technical field [0001] The present disclosure relates to the technical field of supply chain, in particular to a production and transportation collaborative scheduling method and system based on improved harmony search. Background technique [0002] With the development of economic globalization and knowledge economy, users' individual needs are increasing, and the traditional mode of competition among enterprises has been extended to the competition of the entire supply chain. Under the environment of emerging information technology, manufacturing companies no longer focus on the improvement of their own manufacturing capabilities, they tend to design and optimize the entire supply chain. A supply chain is an organization that includes suppliers, customers, products and services, etc. across time and regions. The integration and coordination of these components directly affects the user's satisfaction with the product or service. Therefore, sharing information, collaborat...

AI Technical Summary

Problems solved by technology

However, the traditional collaborative scheduling problem generally does not take into account the fact that multiple suppliers are distributed in different geographical locations and the deterioration effect of processing time

In actual production, the distributed manufacturing mode is ubiquitous, and due to the overload and fatigue of the production line and workers, the actual processing time of the workpiece will increase with the increase of the processing start time

The traditional scheduling method often ignores or abstracts the transportation time as the same, and ignores the deterioration processing time of the workpiece, so it cannot meet the production needs of the current distributed manufacturing enterprises
