Embodiment Construction

[0058] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments shown below are intended to facilitate the understanding of the present invention, but do not have any limiting effect on it.

[0059] like figure 1 As shown, a simplified policy recommendation method for digital twin capabilities of an industrial assembly line consists of the following steps:

[0060] (1) Determine the factors that affect the digitization of the designated industrial assembly line workshop according to the operation status, and divide it into three levels of criteria: elements, twin data, and twin behavior. Each specific program index is classified into the criteria layer, and a digital twin capability evaluation system is established. , which includes a target layer, two criterion layers and a scheme layer;

[0061] like figure 2 As shown in the figure, taking the industrial assembly li...

Abstract

The invention discloses a simplified strategy recommendation method for the digital twinning capacity of an industrial assembly line workshop. The method comprises: determining factors influencing digitization based on three levels of information of elements, data and behaviors of the industrial assembly line workshop; integrating factors to establish a digital twinning ability evaluation system;reflecting consistency level of the entity physical world mapped to the virtual world; and calculating the weight of each system level and the final digital twinning capability by combining an analytic hierarchy process and a multi-objective fuzzy decision analysis method, and giving a simplified strategy recommendation method according to the reduced capability level percentage after the digitization degree of the entity workshop is sequentially reduced. By means of the recommendation strategy simplifying method, the digital twinning capacity level of the workshop can be quantitatively and qualitatively judged in a combined mode, digital factors needing to be improved are clear, and simplified reference suggestions can be provided for the situation that all digital twinning cannot be achieved in the workshop due to limitation of the calculated amount or the storage amount.

Description

technical field [0001] The invention relates to the field of digital twin capability evaluation, in particular to a method for establishing an index of a digital twin capability system and simplifying a strategy recommendation method for an industrial assembly line workshop. Background technique [0002] With the Internet of Things and cyber-physical fusion technology driving a new round of industrial revolution, driven by the maturity of big data processing, cloud computing and related simulation software, as a cutting-edge technology that connects the real world and the virtual world, digital twins have attracted the industrial world. with widespread concern in academia. Digital twin refers to making full use of physical models, sensor updates and historical data to map objects in physical space into virtual space, thereby reflecting the full life cycle process of the corresponding entity. The digital twin capability describes the similarity between virtual space objects ...
