Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0068] A production schedule extraction and tracking method for manufacturing systems based on complex networks. Firstly, a complex network-based manufacturing system network model——manufacturing process information dissemination relationship network (ISRNMP) is established. The network is composed of task dispatching network, task completion feedback network, and pure information transmission network. In order to form the generation mechanism of task dispatching network, task completion feedback network and pure information transmission network; secondly, generate task completion rate and task completion uncertainty based on manufacturing process information dissemination relationship network (ISRNMP), To describe the completion of the manufacturing task; based on the above rules, the evolutionary algorithm of ISRNMP is given, and on this basi...

Abstract

The invention provides a method for extracting production progress of a manufacturing system based on a complex network, aiming at the problems of difficult production progress extraction of an intermittent manufacturing enterprise and tracking of contract execution conditions. The invention particularly adopts an implementation proposal that the method comprises the following steps: firstly, establishing a manufacturing process information dissemination relation net (ISRNMP), wherein the net consists of a task assignment net, a task completion feedback net and a pure information transmission net which are interconnected and interwoven; secondly, establishing a data model for describing a relation among ISRNMP nodes and for describing generative rules of the task assignment net, the task completion feedback net and the pure information transmission net; and thirdly, based on the data model, providing an evolutionary algorithm of the ISRNMP, and then providing the method for extracting the production progress based on the network nodes. The method solves the problem of difficult production progress extraction brought by multisource isomerism information during manufacturing; and the invention provides an intuitive statistic method and a visualized tool for visual monitoring of the production progress in the manufacturing process, and has better application prospect.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing automation, in particular to a method for tracking (or extracting) the production progress of complex manufacturing systems. Background technique [0002] A manufacturing system is an input-output system that transforms manufacturing resources into products or semi-finished products composed of the manufacturing process and its involved hardware, software, and personnel. In the process of transforming manufacturing resources into products or semi-finished products, the manufacturing system forms a complex manufacturing network due to the interweaving of time and space: From the perspective of time, the system includes the signing of contracts, the formulation of production plans, design , manufacturing, assembly to after-sales service; from the perspective of space, the system includes the market operation of the enterprise, enterprises in the supply chain, design department, manufacturing ...
