Embodiment Construction

[0094] The specific implementation manner of the present invention will be described below in conjunction with the technical scheme and accompanying drawings. A flow of an application embodiment is as attached image 3 shown. Based on the analysis of the existing disturbance events in the workshop, this embodiment establishes an event-driven rapid response mechanism, and ensures the guidance of the scheduling plan for the production site through the dynamic scheduling driven by the disturbance event. Four basic processing methods are used: process movement, Different combinations of process cancellation, process addition, and process insertion are used to deal with a large number of different disturbance events from the planning task layer, production process layer, material resource layer, and production execution layer, and realize modular processing. At the same time, in this embodiment With the help of the human-computer interaction mechanism, the existing plan is manuall...

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 ...
