[0079] In this embodiment, characteristic information refers to the information that needs to be paid attention to when laying out and building each material in the warehouse, including but not limited to the type, function, frequency of use, floor space and other information of the material. The preset layout building template is constructed based on the historical layout building template of the materials in the warehouse, and is pre-set, such as the historical layout template and overall framework template of the corresponding materials. The preferred layout building template refers to a layout building template that can meet the characteristic information of the materials.

[0080] In this embodiment, by acquiring the characteristic information of each material in the warehouse, the preferred layout building template of each material is matched in the preset layout building template, and multiple initial layout building methods are obtained according to the preferred layout building template of each material and the corresponding building evaluation values ​​are calculated to obtain the building adaptation rates of various materials in the warehouse, thereby screening out the initial layout building methods with higher building adaptation rates and making multiple corrections to obtain multiple second layout building methods, and simulating the operation in the warehouse for each second layout building method and generating an operation effect evaluation value, and finally selecting the optimal layout building method to improve the storage space and operating efficiency of the warehouse layout and rationalize the warehouse layout.

[0081] In some embodiments of the present application, obtaining characteristic layout information of all materials in the warehouse includes:

[0082] Acquire first information of all materials in the warehouse, wherein the first information includes type information and usage information of the materials;

[0083] At the same time, second information of all materials in the warehouse is obtained, where the second information includes design requirements and style requirements of the materials;

[0084] Generate construction information of corresponding materials according to the first information, the second information and the acquired performance requirement information, wherein the performance requirement information includes: operation speed information, visual information and safety information;

[0085] Perform layout and construction relevance analysis on the construction information, and determine characteristic layout information according to the analysis result.

[0086] In this embodiment, the category information includes the production materials, material properties and management authority of the materials, the usage information includes the main functions of the materials, the needs of the target audience, etc., and the performance requirement information refers to the operating speed, visibility and safety performance of the materials during operation.

[0087] In some embodiments of the present application, based on the characteristic layout information, a preferred layout construction template having a fitness greater than a preset fitness threshold is screened out from the preset layout construction templates, including:

[0088] Pre-set multiple adaptation evaluation indicators;

[0089] Determine the relevant feature layout information of each adaptation evaluation index of the current material according to the correlation between the feature layout information of the same material and the corresponding adaptation evaluation index;

[0094] In this embodiment, the adaptation evaluation index is set according to the category of the feature layout information, and the adaptation evaluation index includes a usage adaptation evaluation index, a design adaptation evaluation index, a performance adaptation evaluation index, and the like.

[0095] In this embodiment, the multi-dimensional adaptation degree between the characteristic layout information and the layout building template is judged according to the adaptation evaluation index. When the adaptation evaluation difference of multiple adaptation evaluation indicators is smaller, it means that the layout building template is more adapted to the characteristic layout information of the corresponding material, that is, it is set as the preferred layout building template for the corresponding material.

[0096] In this implementation, the preferred layout building template for each material is selected relative to a material. The preferred layout building template includes the optimal layout method for a material and the random layout methods for other materials. Therefore, the construction evaluation value of the initial layout building method is subsequently calculated to determine the construction suitability of other materials in a preferred layout building template, thereby gradually improving the storage space and operating efficiency of the warehouse layout.

[0097] In some embodiments of the present application, the entire initial layout construction method is generated according to the preferred layout construction template of each material, including:

[0098] Acquire the planar building information in the warehouse, and generate the planar layout in the warehouse at a preset ratio according to the planar building information;

[0099] Determine a first position of a first material in the plane layout according to a preferred layout template for each material, and determine a plurality of second positions of other materials in the plane layout according to a random arrangement of other materials except the first material;

[0100] Determine multiple initial layout construction methods of the current first material based on the first position and multiple second positions in the plane layout;

[0102] In this embodiment, the first material refers to the material corresponding to the optimal layout method of the preferred layout building template, and all initial layout building methods are determined according to the positional relationship between the first position of the first material and the second position of other materials in the plane layout.

[0103] In this embodiment, the optimal layout method for one of the materials is first determined, and the historical layout methods of other materials are combined with the optimal layout method to form multiple initial layout construction methods. The construction evaluation value of each initial layout construction method is calculated to lay the foundation for the subsequent determination of the optimal layout construction method, and gradually improve the warehouse management level and operational efficiency of the warehouse layout construction.

[0104] In some embodiments of the present application, calculating the construction evaluation value of each initial layout construction method includes:

[0110]

[0111] Among them, Mj is the construction evaluation value of the jth initial layout construction method, g is the construction evaluation conversion coefficient, and e1 is the weight coefficient of the comprehensive supply degree. is the comprehensive supply degree of the jth initial layout construction method, Ci,j is the maximum storage capacity of the i-th material of the j-th initial layout construction method, C0i,j is the average demand for the i-th material of the j-th initial layout construction method, qi,j is the weight coefficient of the i-th material of the j-th initial layout construction method, is the remaining storage space of the jth initial layout construction method, Lj is the comprehensive length of all material chains of the jth initial layout construction method, L0j is the preset length threshold of the jth initial layout construction method, e2 is the weight coefficient of the remaining storage space, is the average fitness of the j-th initial layout construction method, △Pi,j is the fitness of the i-th material of the j-th initial layout construction method, and e3 is the average fitness.

[0112] In this embodiment, based on a comprehensive analysis of the comprehensive supply availability, remaining storage space and average adaptability of each initial layout construction method, initial layout construction methods with construction evaluation values ​​greater than a preset first construction evaluation value are screened out, so as to gradually improve the management level and operational efficiency of the layout construction methods within the warehouse and realize a rational layout within the warehouse.

[0113] In some embodiments of the present application, the selected initial layout construction method is modified multiple times, including:

[0114] Calculate the difference between the construction evaluation value of the selected initial layout construction method and the construction evaluation value of the preset second construction evaluation value threshold;

[0117] Based on the determined correction coefficient interval, several correction schemes are generated for the proportion adjustment coefficient, position adjustment coefficient and distance adjustment coefficient in the corresponding initial layout building method, and based on each correction scheme, the corresponding initial layout building method is corrected to obtain multiple second layout building methods.

[0118] In this embodiment, the preset correction model is constructed based on the correction coefficient of the historical warehouse layout construction method. The proportion adjustment coefficient, position adjustment coefficient and distance adjustment coefficient of the screened initial layout construction method are corrected according to the preset correction model and the correction coefficient range, thereby improving the rationality of the initial layout construction method and the operation efficiency of materials. On the premise of ensuring safety, the storage space is fully utilized to achieve the purposes of orderly partitioning and easy operation.

[0119] In some embodiments of the present application, a simulation of the operation in the warehouse is performed for each second layout construction method, including:

[0120] Determine the location information and structure information of the materials involved in each second layout construction method, and lock the location of the panoramic map of the warehouse to obtain a static simulation scene of each second layout construction method;

[0121] Preset multiple demand instructions for operation in the warehouse, and obtain the corresponding dynamic simulation scene to be set according to each demand instruction;

[0122] Obtain the supply demand of corresponding materials in the dynamic simulation scenario to be set, and establish a dynamic operation trajectory under the supply demand;

[0124] The simulation results of each second layout construction method for multiple demand instructions operating in the warehouse are obtained according to the simulation model.

[0125] In this embodiment, the demand instructions include the material characteristics, supply requirements, operation paths, etc. of specific materials, which are set in advance. The static simulation scene refers to the scenes, fixed equipment and weather involved in the warehouse, and the dynamic simulation scene refers to the dynamic relationship between material operations based on the demand instructions.

[0126] In this embodiment, a simulation model of the current second layout construction method is built through dynamic simulation scenarios and static simulation scenarios to simulate the material operation efficiency under different demand instructions, and obtain and analyze the materials and material operation efficiency involved in multiple demand instructions in the second layout construction method, which is conducive to discovering and improving the deficiencies in the warehouse layout, thereby improving the warehouse management level and material operation efficiency.

[0127] In some embodiments of the present application, the operation effect evaluation is performed according to the simulation results, including:

[0128] Based on multiple demand instructions, a simulation is performed in each simulation model to obtain the virtual operation occupied area of ​​the materials corresponding to each dynamic operation trajectory in the simulation model, and the overlap of the virtual operation occupied areas of the materials involved in the same demand instruction is determined;

[0129] According to the overlap and the material's importance coefficient, set the extended operation time of the materials involved in the corresponding demand instruction, and generate the operation efficiency of the corresponding materials under the corresponding demand instruction according to the supply demand of the materials and the extended operation time;

[0130] Compare the operation efficiency of materials involved in multiple demand instructions with the corresponding preset standard operation efficiency, generate the operation efficiency difference of materials involved in the corresponding demand instructions according to the comparison result, and generate the comprehensive operation efficiency difference of the corresponding demand instructions according to the multiple operation efficiency differences;

[0131] According to the relationship between the comprehensive operation efficiency difference of materials involved in multiple demand instructions under the same simulation model and the preset comprehensive operation efficiency difference threshold, the operation effect of the corresponding simulation model is evaluated;

[0132] The calculation formula for the operation effect evaluation is:

[0133] ;

[0134] Wherein, Ky is the operation effect evaluation result of the yth simulation model, w is the total number of demand instructions, Rs,y is the comprehensive operation efficiency of the sth demand instruction of the yth simulation model, and R0s,y is the preset comprehensive operation efficiency difference threshold of the sth demand instruction of the yth simulation model;

[0135] Based on the result of the operation effect evaluation, the multiple simulation models are sorted by size, and the second layout construction method corresponding to the simulation model ranked first is set as the optimal layout construction method.

[0136] In this embodiment, the overlap refers to the difference in the virtual operation occupied areas of the materials involved in the same demand instruction. The operation efficiency = supply demand / (virtual operation time + operation extension time). The virtual operation time refers to the operation time of only one material under the dynamic operation trajectory of the corresponding simulation model.

[0137] In this embodiment, each simulation model is sorted according to the evaluation results of its operating effect, and the second layout construction method corresponding to the simulation model ranked first is set as the optimal layout construction method. The optimal layout construction method means that the construction adaptability, operation efficiency and warehouse storage utilization rate of each material are the best layout construction method, thereby improving the warehouse management level and material operation efficiency.

[0138] In some embodiments of the present application, the operation extension time of the materials involved in the corresponding demand instruction is set according to the overlap degree and the importance coefficient of the materials, including:

[0139] Presetting a first preset overlap threshold interval, a second preset overlap threshold interval, a third preset overlap threshold interval and a fourth preset overlap threshold interval;

[0140] When the overlap degree is within the first preset overlap degree threshold range, the comprehensive operation extension time is set to the first preset comprehensive operation extension time T1;

[0141] When the overlap degree is within the second preset overlap degree threshold range, the comprehensive operation extension time is set to the second preset comprehensive operation extension time T2;

[0142] When the overlap degree is within the third preset overlap degree threshold range, the comprehensive operation extension time is set to the third preset comprehensive operation extension time T3;

[0143] When the overlap degree is within the fourth preset overlap degree threshold range, the comprehensive operation extension time is set to the fourth preset comprehensive operation extension time T4;

[0144] Among them, T1<T2<T3<T4;

[0145] According to the ratio of the importance coefficient and the comprehensive importance coefficient of the materials involved in the same demand instruction, the i-th preset comprehensive operation extension time Ti is divided, and the operation extension time of the materials involved in each demand instruction is determined according to the division result.

[0146] In this embodiment, the importance coefficient is set according to the adaptability of the material in the corresponding second layout construction method. When the adaptability is large, the importance coefficient is also large. For example, the materials involved in the same demand instruction are a, b, c, and d, and the corresponding importance coefficients are 0.6, 0.3, 0.2, and 0.7, respectively. The comprehensive importance coefficient is 0.6+0.3+0.2+0.7, and the ratio of material a is 0.6 / (0.6+0.3+0.2+0.7)=0.33. Then the operation extension time of material a=Ti*0.33.
