Embodiment Construction

[0056] The present invention will be further described below in conjunction with the content of the present invention and the embodiments described in the accompanying drawings.

[0057] The present invention provides a network collaborative production scheduling system based on Virtual-Hub, its structure is as follows figure 1 shown. The network collaborative production scheduling system based on Virtual-Hub is a network virtual platform that can be accessed through standard Web protocols (HTTP, WSDL) and Servelet engine.

[0058] The system adopts B / S structure in the overall structure, and mainly adopts J2EE technology with strong portability, HTML, JSP (Java Service Pages), XML and Web Service technology in the system construction. At the same time, according to the characteristics of the system, the relatively mature open source frameworks such as Hibernate, Struts, Spring and ibatis and JFreeChart drawing components are adopted. The server side uses JSP technology to r...

Abstract

The invention relates to a Virtual-hub-based network coordinated production scheduling system, which comprises an information sharing module, a plan scheduling module and a Virtual-Hub of a production synchronization module, wherein the information sharing module comprises an enterprise basic information module, a product material information module, and a plan scheduling information module; the plan scheduling module comprises plan decomposition, task distribution and dynamic scheduling; and the production synchronization module is used to send latest production information commands to other manufactures on a production chain to ensure the longitudinal synchronization of enterprises in coordinated production plan. A self-adaptive scheduling method based on network coordinated production aims to obtain a better or good plan scheduling policy at cost as low as possible when an uncertain event happens in an enterprise at a time T during coordinated production, so as to readjust internal production plan dynamically.

Description

technical field [0001] The invention relates to a method and system for production collaboration and control, in particular to a method and system for production collaboration and control in a manufacturing industry network production environment. Background technique [0002] The networked collaborative production process is a unitized, autonomous, parallel, virtual, and distributed manufacturing process. Manufacturing enterprises are dynamically organized together to complete common tasks. This multi-enterprise collaborative production model, because each enterprise participates in multiple production chains, criss-cross to form a complex production system. The participating enterprises in networked manufacturing are in a dynamic and changeable environment, the uncertainty and dynamics of the internal and external environment of the enterprise's production increase, and the occurrence of uncertain events is the inducing factor for the dynamic adjustment of production plann...
