Problems solved by technology

[0002] In the production and processing of glass, paper, wood and other industries, it provides reasonable layout plans and calculates the quantity and specifications of raw materials that need to be purchased, so as to improve the utilization rate of raw materials and save a lot of resources for enterprises; it can also be based on actual production constraints. Select reasonable raw material specifications on the basis of the above, and design a reasonable layout layout; the existing layout method is to use different optimization calculation methods to optimize the layout of rectangular workpieces, so as to maximize the utilization of plate originals ; Its optimization effect is relatively poor, it is difficult to optimize the selection of multi-standard plate originals and the mechanism of gradually relaxing the area, and optimize the single rectangular original sheet to realize the layout and optimization of rectangular workpieces. The function of breaking up and reorganizing the unsatisfactory plate originals

Embodiment Construction

[0032] Such as figure 1 The shown rectangular layout method for multi-standard plates, the method includes the following steps:

[0033] The first step is to input the initial data of the plate and rectangular workpiece;

[0034] In the second step, according to the specifications and quantities of rectangular workpieces, the layout of multi-standard plates is carried out through the multi-standard plate layout module;

[0035] The third step is to obtain the plate combination sequence through the plate combination structure algorithm according to the total area of ​​the workpiece, the plate specification and quantity; the plate combination sequence is relaxed to select the plate combination to obtain the plate combination; The single-plate layout algorithm of the optimization strategy calculates whether the plate combination can arrange all the workpieces, if not, it will go back to the relaxed selection of the plate combination; if it can, output the layout of the plate pa...

Abstract

The invention discloses a multi-specification plate-oriented rectangular part layout method. The method includes the steps of: 1. inputting initial data of plates and rectangular workpieces; 2. carrying out the multi-specification plate layout through a multi-specification plate layout module according to the specifications and the number of the rectangular workpieces; 3. obtaining a plate combination sequence through a plate combination construction algorithm according to the total area of workpieces, the specifications and the number of the plates; performing broadened selection of plate combinations on the plate combination sequence to obtain a plate combination; and then calculating whether the plate combination can discharge all the workpieces through a grouping strategy-based single-plate layout algorithm in the multi-specification plate layout module, if the plate combination cannot discharge all the workpieces, tracing back to the broadened selection of plate combinations, and if the plate combination can discharge all the workpieces, outputting the plates subjected to the layout. The multi-specification plate-oriented rectangular part layout method provided by the invention breaks the limitation of unreasonable selection of only original rectangular parts and unreasonable layout of single plates in the prior art, and has a wider range of application.

Description

technical field [0001] The invention relates to a layout method for rectangular pieces facing multi-standard boards, and belongs to the technical field of layout methods. Background technique [0002] In the production and processing of glass, paper, wood and other industries, it provides reasonable layout plans and calculates the quantity and specifications of raw materials that need to be purchased, so as to improve the utilization rate of raw materials and save a lot of resources for enterprises; it can also be based on actual production constraints. Select reasonable raw material specifications on the basis of the above, and design a reasonable layout layout; the existing layout method is to use different optimization calculation methods to optimize the layout of rectangular workpieces, so as to maximize the utilization of plate originals ; Its optimization effect is relatively poor, it is difficult to optimize the selection of multi-standard plate originals and the mech...
