Shop operation dynamic dispatching method based on disturbance event driving

Abstract

The invention aims at providing an effective dynamic dispatching mechanism for shop dispatching operation directing at multi-species variable volume production environment, thus completing production dispatching scheme determination and optimization under the disturbance of shop production. The method is based on analysis of the existing shop disturbance event, an event-driven fast response mechanism is established, guiding of dispatching scheme on production field is ensured by dynamic dispatching on disturbance event driving, four basic processing methods are utilized, different combination of process movement, process cancel, process addition and process insertion are utilized to deal with massive and different disturbance events from a scheduled task layer, a production technology layer, a material resource layer and a production execution layer, modular processing is realized, and meanwhile the scheme can make the best of experience of dispatching personnel by virtue of human-machine interaction mechanism, causes the optimized scheme to be more corresponding to shop production habit and improves the applicability of the dispatching scheme.

Description

field of invention [0001] The invention relates to a method for realizing dynamic scheduling of workshop operations, which belongs to the category of manufacturing execution system technology in the field of modern manufacturing integration technology and automation, and particularly relates to a dynamic scheduling mechanism of workshop operations in a complex dynamic environment. Background technique [0002] At present, with the continuous improvement of the degree of automation of enterprises and the transformation of the production mode of manufacturing enterprises to multi-variety variable batch mode, in order to improve production efficiency and reduce production costs, it is necessary to comprehensively control the processing process of the production workshop, that is, Realize the dynamic scheduling of the workshop. [0003] The so-called dynamic scheduling of workshop operations means that when the workshop executes according to the original job scheduling plan, it ...

AI Technical Summary

Problems solved by technology

[0004] At present, enterprises are generally in the production environment of multi-variety variable batch production, and the workshop scheduling is facing new problems: the execution environment of the multi-variety variable batch production mode has the characteristics of uncertainty, inaccuracy and incompleteness. Production disturbances in production planning, turnover process, equipment and materials, etc.

[0007] (1) The scheduling algorithm is too theoretical, it cannot be well combined with the actual workshop production, and it is difficult to adapt to the complex workshop production environment

[0008] (2) The scheduling software does not have the ability to respond in a timely manner, and cannot respond in time to the disturbance time in the workshop processing process, making the theoretical scheduling plan lose its guiding significance

[0009] The human-computer interaction of the dispatching software is poor, and the dispatching plan that has been automatically generated cannot be manually modified, and the production experience of the enterprise dispatcher cannot be fully used.

The scheduling scheme cannot adapt to the production culture of the enterprise, and the usability is poor
