Supply-demand matching and dynamic scheduling method of manufacturing service based on hypernetwork

Abstract

This invention relates to a supply-demand matching and dynamic scheduling method of manufacturing service based on a hypernetwork. The method comprises the following steps: A, constructing a supply-demand matching hypernetwork model of the manufacturing service; B, before a task is executed actually, pre-scheduling the manufacturing service of an initial time; C, performing isometric and continuous division to the dynamic scheduling time of the manufacturing service according to units of unit time; from the time unit t=1, periodically generating a dynamic environment and executing the update of the hypernetwork at the interval of each unit of the unit time; D, if the hypernetwork changes, executing dynamic scheduling judge; otherwise, entering the next time unit, or finishing if the judge meets a stopping criterion; E, and if the current scheduling scheme is destroyed, executing dynamic rescheduling to generate a new scheduling scheme. The method provided by the invention can effectively reflect the dynamic environment in the service-oriented manufacturing system, and can ensure the validity of the dynamic scheduling of the manufacturing service and higher cooperation reliability of participant enterprises.

Description

technical field [0001] The invention belongs to the technical field of supply-demand matching and optimal configuration of manufacturing services and manufacturing tasks in a service-oriented manufacturing (Service-oriented Manufacturing, SoM) system, and specifically relates to a method for supply-demand matching and dynamic scheduling of manufacturing services based on a super network. Background technique [0002] In the SoM system, various manufacturing resources and manufacturing capabilities exist in the form of manufacturing services after certain perception and access, virtualization, and service-oriented processing, and can be aggregated, retrieved, and invoked through the network, serving as a social users provide various applications for the whole life cycle. At the same time, all production-related or product-related tasks and other service requirements involved in the product lifecycle process exist in the form of manufacturing tasks, and these manufacturing tas...

Problems solved by technology

However, most of these studies mainly focus on the supply-demand matching problem at a certain moment and provide solutions, but the current research is insufficient for the dynamic matching of supply and demand under the conditions of resource service and task demand being uncertain or dynamically changing.

At the same time, due to the socialization of manufacturing, the scale of supply and demand continues to expand, and the simplified mathematical model can no longer meet actual needs.
