Embodiment Construction

[0055] A HoloLens-based intelligent assembly production line simulation method proposed by the present invention is described in detail in conjunction with the accompanying drawings as follows:

[0056] The method proposed by the present invention, based on the HoloLens head-mounted display device, is used for the assembly simulation of the discrete mixed-flow assembly line. There is a clear correspondence between the assembly process and the equipment in the discrete mixed-flow assembly line, and there is no priority difference between different products. Use this as an assembly line feature. The specific process of this method is as follows:

[0057] 1) Mathematical modeling and simulation is carried out on the production scheduling of the assembly line. Through this step, the actual assembly process is abstracted into a mathematical problem. The specific steps are as follows:

[0058] 1-1) Determine the constraints

[0059] According to the characteristics of the assembly...

Abstract

The invention provides a HoloLens-based intelligent assembly production line simulation method. The method comprises the following steps of firstly performing mathematical modeling and simulation on the arrangement scheduling of the assembly line; converting the multi-objective flexible job shop scheduling problem into a mixed integer programming model, including the steps of determining a constraint condition, selecting an optimization target and performing mathematical modeling according to the selected optimization target; solving the mixed integer programming model by using the improved genetic algorithm to obtain an arrangement scheduling scheme; and finally presenting the obtained arrangement scheduling scheme to the user through the HoloLens head-mounted device equipment. The HoloLens-based intelligent assembly production line simulation method provided by the invention can shorten the product assembly cycle, reduce the product assembly cost and improve the product assembly quality, and on the other hand, enhances the user interaction experience by utilizing the HoloLens head-mounted display equipment.

Description

technical field [0001] The invention belongs to the technical field of intelligent assembly production line simulation, in particular to a method for simulating an intelligent assembly production line based on HoloLens. Background technique [0002] In intelligent manufacturing, intelligent assembly is a very important part. Because in a complete manufacturing cycle, product assembly is one of the most time-consuming and cost-consuming links, often taking up more than 40% of manufacturing costs and man-hours. At the same time, as assembly is a relatively late step in manufacturing, the accuracy and quality will directly affect the final product. Once a problem occurs and rework is required, it may bring risks in terms of schedule, cost and performance. In the assembly process, production scheduling is very important. [0003] Specifically, production scheduling defines limited resources as equipment in the workshop, and its solution objective can be defined as arranging ea...
