Abstract

The invention provides a method for adapting the running position of an edge-cloud collaborative digital twin intelligent production scheduling application. The applied intelligent production scheduling system includes a cloud layer, an edge layer and a device layer. The generated digital twin system is set at both the edge layer and the cloud layer; an adaptation strategy controller is set at the cloud layer. The adaptation strategy controller dynamically senses the edge and cloud resource status, application attributes, etc. in the production process, aiming at minimizing the delay of the digital twin intelligent production scheduling decision cycle, and has two types of intelligence for the digital twin: deterministic environment and non-deterministic environment. Real-time adaptation and switching of the running position of the production scheduling application; real-time adaptation and switching of the running position of the digital twin intelligent production scheduling application based on prediction in a non-deterministic environment. Using the method of the invention to determine the running position of the digital twin intelligent production scheduling application reduces the performance impairment caused by the digital twin based system due to the delay in data interaction and command issuance, and improves the guarantee of the digital twin based production scheduling accuracy.

Description

technical field [0001] The invention relates to the technical fields of industrial intelligent production scheduling, digital twinning, edge computing and the like, in particular to a method for adapting the running position of an industrial digital twin intelligent production scheduling application based on edge-cloud collaboration. Background technique [0002] Implementing Job Shop Scheduling (JSS, Job Shop Scheduling), that is, intelligent scheduling refers to the process of allocating production tasks to production resources. Under the premise of considering the capacity and equipment, under the condition of a certain number of materials, arrange the production sequence of each production task, optimize the production sequence, and optimize the selection of production equipment, so as to reduce the waiting time, balance the production load of each machine and workers, so as to optimize capacity and improve production efficiency. [0003] Production scheduling assigns a...
