Description

Maintenance equipment dimension-reducing intelligent boxing method based on drawer intermediation Technical Field The invention relates to a maintenance equipment dimension-reducing intelligent boxing method based on drawer intermediation, and belongs to the technical field of equipment packaging assembly. Background In a military equipment maintenance equipment support system, the basic number assembly and complete supply are core support modes, and the equipment maintenance equipment is required to be stored and transported in a standardized package mode after being assembled according to a preset basic number standard. However, the boxing of equipment maintenance equipment essentially belongs to the problem of typical three-dimensional boxing NP-hard, the computational complexity of the equipment maintenance equipment increases exponentially along with the increase of the quantity of equipment, and the traditional three-dimensional boxing algorithm needs to optimize the space layout of three dimensions of length, width and height at the same time, so that the computational consumption of 100 heterogeneous equipment in a single batch is often more than 30 minutes, and the requirement of rapid boxing is difficult to meet. Meanwhile, the existing equipment maintenance equipment boxing is mostly dependent on manual sorting and trial boxing modes, and the problems that firstly, the space utilization rate is low, the space utilization rate of the manual trial boxing is generally lower than 45%, the use amount of containers is increased, the waste of the operation capacity in war is serious, secondly, the artificial interference factors are more, the scheme design randomness of different sets of units is large, multiple packaging sets of formulas can appear on equipment of the same model equipment, standardization is lacking, and thirdly, the suitability is poor, although the prior art has a partial dimension reduction method, such as the three-dimensional problem is simplified into two-dimensional problem, but aiming at the general logistics scene design, the characteristics of military equipment base set matching and complete set supply are not combined, the suitability of equipment height and drawer depth is often ignored by the general dimension reduction method, so that the reworking of partial equipment is required due to the fact that the height is out of tolerance, or the space waste in the drawer depth direction is serious, and the calculation efficiency and the scheme practicability cannot be considered. In addition, the specificity of the equipment maintenance equipment sets additional constraint requirements on the boxing scheme, namely, on one hand, the precision equipment (such as radar accessories and optical instruments) needs to avoid stacking and repressing, on the other hand, the complete equipment (such as an engine maintenance kit) needs to be ensured to be in the same packaging unit, and the traditional three-dimensional boxing algorithm and the general dimension reduction method are difficult to meet the constraint requirements at the same time, so that the boxing scheme does not meet the storage specification of the equipment maintenance equipment, or the calculation efficiency is low, and the requirements of quick response and precise guarantee in the war cannot be adapted. Therefore, in order to solve the above problems, it is necessary to design a three-dimensional boxing optimization method that combines the characteristics of the equipment and combines the calculation efficiency and the practical applicability of the solution. Disclosure of Invention In order to solve the problems, the invention provides a maintenance equipment dimension-reducing intelligent boxing method based on drawer intermediation, which uses a drawer as intermediation to disassemble a complex three-dimensional boxing problem into two-stage resolving logic for planning a two-dimensional area in the drawer and a one-dimensional height in a container, so that the computational complexity is reduced, meanwhile, the scheme is ensured to meet constraint requirements of equipment standardization and unitization, and triple targets of boxing efficiency improvement, space utilization optimization and scheme practicality guarantee are finally realized. The maintenance equipment dimension-reducing intelligent boxing method based on drawer intermediation is suitable for standardized and refined assembly boxing scenes of military equipment maintenance equipment (such as mechanical parts, electronic elements, precise instruments and the like), is especially suitable for a storage guarantee mode of military maintenance equipment with basic number assembly and complete supply, can remarkably reduce the calculation complexity of three-dimensional boxing problems and improves boxing efficiency and space utilization rate, and comprises the following steps: step 1, data preprocessing and high-level grouping, Firstly, sorting all
