Among them, the method can be applied to a terminal, a server, or a system including a terminal and a server, and is realized through the interaction between the terminal and the server. Among them, the terminal can be, but is not limited to, various personal computers, laptops, etc. Among them, the terminal combines the platform material information of the building material and the platform interaction information, thereby first generating a building material association call network from the three perspectives of the material information, flow characteristics, and evaluation results of the building material, so that when controlling a single building material, it is possible to uniformly control each building material with associated information of the building material, avoid the low timeliness, repetition, and low efficiency of individually controlling each building material, and improve the unified control efficiency of the building material.

[0066] In an exemplary embodiment, Figure 1 As shown, a supply chain intelligent management and control method based on building material flow analysis is provided, and the method is applied to a terminal as an example for explanation, including the following steps S101 to S103. Among them:
[0067] Step S101, obtaining platform material information of each building material of the supply chain platform and platform interaction information of each building material, and generating a building material association call network based on the platform material information of each building material.
[0068] In this embodiment, the terminal obtains the platform material information of each building material of the supply chain platform and the platform interaction information of each building material by querying the building material information of each building material of the supply chain platform, the flow information of each building material, and the online communication information. Among them, the building material information includes the brief introduction information of the building material, the source information of the building material (for example, the source merchant, the source interface, the source client, etc.), the supply chain node of the building material, and the material type of the building material. Among them, the supply chain platform includes the full supply chain node of the construction industry, and each supply chain node corresponds to a sub-industry or sub-category node of the construction industry. For example, the basic raw material node, the decoration material node, the beautification material node, the plumbing material node, the lighting material node, and the furniture material node, etc. The flow information of the building material includes transaction information, circulation information (for example, overall activities, multi-type building material packages, etc., and the activity circulation information of the building material. And the online communication information includes material communication information and material evaluation information. Finally, the terminal generates a building material association call network based on the platform material information of each building material. Among them, the building material association call network is a building material call association map, and the association map includes the association information between each building material. The specific generation process will be described in detail later.
[0069] Step S102, based on the platform interaction information of each building material, identify the flow characteristics of each building material and the evaluation results of each building material, and generate a management and control call strategy for each building material based on the flow characteristics of each building material and the evaluation results of each building material.
[0070] In this embodiment, the terminal identifies the flow characteristics of each building material and the evaluation results of each building material based on the platform interaction information of each building material, and generates a control and call strategy for each building material based on the flow characteristics of each building material and the evaluation results of each building material. Among them, the flow characteristics include the trajectory characteristics of different flow trajectories of the building material on the platform. And the evaluation results of each building material include the key evaluation content of each evaluation information and the evaluation type of each evaluation information. The specific identification process will be described in detail later. Among them, the control and call strategy is a comprehensive control method for controlling the call of building materials and the flow mode of building materials. Each building material corresponds to a control and call strategy, and the specific generation method of the control and call strategy will be described in detail later.
[0071] Step S103, based on the building material association call network and the control call strategy of each building material, dynamic control information of the building material of the supply chain platform is generated.
[0072] In this embodiment, the terminal generates dynamic control information of building materials of the supply chain platform based on the building material association call network and the control call strategy of each building material. The specific generation method will be described in detail later.
[0073] Based on the above scheme, by combining the platform material information of building materials and the platform interaction information, from the three perspectives of material information, flow characteristics, and evaluation results of building materials, the building material association call network is first generated, so that when controlling a single building material, the building materials with associated information can be uniformly controlled, avoiding the low timeliness, duplication, and low efficiency of individual control of each building material, and improving the efficiency of unified control of building materials. Then, based on the flow characteristics of the building material and the evaluation results, this scheme generates a control call strategy for each building material, so that when the building material is controlled and called, it can be based on the flow of the building material and the user's evaluation, and the building material can be targeted for comprehensive control, thereby improving the flow control effect of the building material and the user's evaluation satisfaction. Finally, this scheme combines the constructed building material association call network and the control call strategy of each building material, and comprehensively controls the dynamic control information of each building material, so that when all building materials in the supply chain are comprehensively controlled, it can ensure the efficiency and accuracy of control, and can also improve the control effect of each building material, thereby comprehensively improving the control effect of building materials on the supply chain platform.
[0074] Optionally, based on the platform material information of each building material, a building material association call network is generated, including: based on the platform material information of each building material, identifying the supply chain node corresponding to each building material and the material type of each building material, and based on the material profile information in the platform material information of each building material, extracting the material feature information of each building material through a feature extraction network; based on the supply chain node corresponding to each building material and the material type of each building material, constructing a building material association architecture, and based on the material feature information of each building material and the material type corresponding to each building material, generating a building material association call network through the building material association architecture.
[0075] In this embodiment, the terminal identifies the supply chain node corresponding to each building material and the material type of each building material based on the platform material information of each building material, and extracts the material feature information of each building material through a feature extraction network based on the material profile information in the platform material information of each building material. The feature extraction network is a text feature extraction network, which is a large language model based on natural language processing technology.
[0076] Among them, the material types of each building material mainly include inorganic materials, organic materials and composite materials. Inorganic materials include metal materials (such as steel) and non-metallic materials (such as cement, concrete, bricks and tiles, ceramics, etc.). Organic materials mainly include plant materials, synthetic polymer materials (such as plastics, coatings, adhesives) and asphalt materials. Composite materials are composed of inorganic non-metallic materials and organic materials, such as asphalt concrete, polymer concrete, etc. In terms of specific classification, building materials can be divided into structural materials, decorative materials and special materials. Structural materials are used to support and stabilize buildings, such as steel bars, cement, wood, stone, etc. Decorative materials are used to beautify buildings, such as coatings, tiles, glass, etc. Special materials have special functions, such as waterproofing, moisture-proofing, heat preservation, sound insulation, etc. In addition, building materials can also be divided into floor building materials, wall building materials, sanitary ware building materials and thermal insulation building materials according to their uses. Floor building materials include various wooden floors and composite floors. Wall building materials such as tiles, wallpaper, etc. Sanitary ware building materials include faucets, toilets, etc. Thermal insulation building materials are used to improve the thermal insulation performance of buildings, such as rock wool boards, foam cement boards, etc.
[0077] Finally, the terminal constructs a building material association framework based on the supply chain node corresponding to each building material and the material type of each building material, and generates a building material association call network through the building material association framework based on the material feature information of each building material and the material type corresponding to each building material. Specifically, the method of generating a building material association call network will be described in detail later.
[0078] Based on the above scheme, by identifying the material types, material characteristics, and supply chain nodes corresponding to the building materials, a building material association call network of the building materials is generated. Therefore, when managing a single building material, it is possible to uniformly manage all building materials that have associated information with the building material, avoiding the problems of low timeliness, duplication, and low efficiency of individual control of each building material, thereby improving the efficiency of unified control of building materials.
[0079] Optionally, based on the material characteristic information of each building material and the material type corresponding to each building material, a building material association call network is generated through a building material association architecture, including: dividing each building material according to the material type corresponding to each building material to obtain building material groups of each material type, and for each building material group, based on the material characteristic information of each building material in the building material group, calculating the similarity between each building material through a similarity recognition algorithm; based on the similarity between each building material, generating a first material association strength between each building material, and identifying each associated building material with association information based on the building material association architecture; based on the material characteristic information of each associated building material in different building material groups, calculating the similarity between each associated building material through a similarity recognition algorithm, and generating a second material association strength between each associated building material based on the similarity between each associated building material; based on the first material association strength between each building material and the second material association strength between each associated building material in different building material groups, adjusting the association information between the building material association architectures to obtain a building material association call network.
[0080] In this embodiment, the terminal divides each building material according to the material type corresponding to each building material to obtain each building material group of each material type, and for each building material group, based on the material feature information of each building material in the building material group, calculates the similarity between each building material through a similarity recognition algorithm. The similarity recognition algorithm is a cosine similarity recognition algorithm.
[0081] The terminal generates a first material association strength between each building material based on the similarity between each building material, and identifies each associated building material having association information based on the building material association architecture. The terminal calculates the similarity between each associated building material based on the material feature information of each associated building material of different building material groups through a similarity recognition algorithm, and generates a second material association strength between each associated building material based on the similarity between each associated building material. The terminal normalizes the similarity to obtain the material association strength between the associated building materials.
[0082] Finally, the terminal adjusts the association information between the building material association frameworks based on the first material association strength between each building material and the second material association strength between each associated building material of different building material groups to obtain a building material association call network.
[0083] Based on the above scheme, by identifying the similarities between related building materials, the material association strength between each building material type and the material association strength between building materials with associated information are determined, thereby improving the comprehensiveness and accuracy of the constructed building material association call network.
[0084] Optionally, based on the platform interaction information of each building material, the flow characteristics of each building material and the evaluation results of each building material are identified, including: for each building material, splitting the platform interaction information of the building material into platform communication information of the building material and platform flow information of the building material; identifying each evaluation information in the platform communication information through an evaluation recognition network, and respectively identifying the key evaluation content of each evaluation information and the evaluation type of each evaluation information through a semantic recognition network; taking the key evaluation content of each evaluation information and the evaluation type of each evaluation information as the evaluation result of the building material; generating a platform flow trajectory map of the building material based on the platform flow information of the building material, and extracting the flow characteristics of the building material through an image feature extraction network based on the platform flow trajectory map.
[0085] In this embodiment, the terminal splits the platform interaction information of the building material into the platform communication information of the building material and the platform flow information of the building material for each building material. The record information of each building material includes the communication identification of the platform communication information and the flow identification of the platform flow information. The identification information may be a title identification, a text identification, a color identification, a code identification, etc. The terminal splits the platform interaction information of the building material into the platform communication information of the building material and the platform flow information of the building material by identifying each identification information.
[0086] Then, the terminal identifies each evaluation information in the platform communication information through the evaluation recognition network, and identifies the key evaluation content of each evaluation information and the evaluation type of each evaluation information through the semantic recognition network. Among them, the evaluation recognition network is a text classification neural network based on natural language processing technology, and the neural network is used to screen the evaluation information in the communication information. Among them, the evaluation type includes but is not limited to a positive evaluation type, a negative evaluation type, a medium evaluation type, etc.
[0087] Afterwards, the terminal uses the key evaluation content of each evaluation information and the evaluation type of each evaluation information as the evaluation result of the building material.
[0088] Finally, the terminal generates a platform flow trajectory map of building materials based on the platform flow information of building materials, and extracts the flow features of building materials through the image feature extraction network based on the platform flow trajectory map. The platform flow trajectory map uses the platform architecture of the entire platform as the trajectory plane, and displays the flow trajectory of the building materials in the platform architecture in the trajectory plane, wherein at each trajectory point of the trajectory, the flow content corresponding to the trajectory point is marked, such as transaction volume, transaction party, transaction time, transaction result and other information. The image feature extraction network is a CNN convolutional neural network based on self-attention memory.
[0089] Based on the above solution, after splitting the interactive information, the flow characteristics of each building material and the evaluation results of each building material are identified from the two perspectives of circulation information and evaluation information, thereby improving the comprehensiveness and accuracy of the identification of the circulation information of each building material.
[0090] Optionally, based on the flow characteristics of each building material and the evaluation results of each building material, a management and control call strategy for each building material is generated, including: for each building material, based on the flow characteristics of the building material, identifying the transaction preference information of the building material and the preferred flow route of the building material, and based on the evaluation results of each building material, identifying the material quality information of each building material; based on the material type of the building material and the supply chain node of the building material in the supply chain platform, querying the management and control call demand information of the building material and the initial management and control call strategy of the building material in the supply chain database, and based on the management and control call demand information of the building material, identifying the flow management and control demand information of the building material and the material call demand information of the building material; based on the transaction preference information of the building material and the preferred flow route of the building material, identifying the flow difference information of the building material through the flow management and control demand information of the building material, and based on the material quality information of the building material, identifying the call difference information of the building material through the material call demand information of the building material; based on the flow difference information of the building material and the call difference information of the building material, adjusting the initial management and control call strategy of the building material to generate the management and control call strategy of the building material.
[0091] In this embodiment, the terminal identifies the transaction preference information of each building material and the preferred flow route of the building material based on the flow characteristics of the building material, and identifies the material quality information of each building material based on the evaluation results of each building material. Among them, the quality information is the advantages and disadvantages of the building material. Advantages include hard structure, good heat resistance, unique shape, no odor, good shape, etc., while disadvantages include unsuitable for processing, fast aging, fixed shape, etc. The transaction preference information is the top target trading parties among the trading parties of the building material after being sorted according to transaction volume and transaction frequency (the number of the top few can be preset in the terminal). The transaction method and transaction conditions of each target trading party are the transaction preference information of the building material. The preferred flow route is the sub-trajectory with the top few track repetition times in the flow trajectory of the building material (the number of the top few can be preset in the terminal).
[0092] Based on the material type of the building materials and the supply chain node of the building materials in the supply chain platform, the terminal queries the control and call demand information of the building materials and the initial control and call strategy of the building materials in the supply chain database, and identifies the flow control demand information of the building materials and the material call demand information of the building materials based on the control and call demand information of the building materials. Among them, the material control demand information is the transaction mode, transaction conditions, and flow route restriction information of the building materials. Then. The terminal identifies the flow difference information of the building materials through the flow control demand information of the building materials based on the transaction preference information of the building materials and the preferred flow route of the building materials. The transaction mode, transaction conditions, and flow route that are different from the transaction mode, transaction conditions, and flow route restriction information of the building materials are identified, and the transaction mode, transaction conditions, and flow route of the different building materials are used as the flow difference information of the building materials. The material call demand information includes the restriction information of the disadvantages of the building materials (i.e., the disadvantages that cannot exist in the building materials or the degree of existence is limited, for example, the hardness cannot be the first strength, the service life cannot be less than a certain number of years, and the elements in the odor cannot contain which types of elements, etc.). Then, based on the material quality information of the building materials and the material calling demand information of the building materials, the mid- to high-end identifies all disadvantages of the building materials that exceed the disadvantage limit information of the building materials as the calling difference information of the building materials.
[0093] Finally, the terminal adjusts the initial control and call strategy of the building materials based on the flow difference information of the building materials and the call difference information of the building materials, and generates a control and call strategy of the building materials. The control and call strategy is a control and call strategy for restricting the flow difference information and the call difference information.
[0094] Based on the above solution, by restricting and controlling building materials from two perspectives, namely, flow difference information and call difference information, the efficiency and accuracy of restriction and control of building materials are improved.
[0095] Optionally, based on the building material associated call network and the control and call strategy of each building material, dynamic control information of building materials for the supply chain platform is generated, including: based on the building material associated call network, identifying the associated building materials corresponding to each building material, and for each building material, based on the building material's control and call strategy, the control and call strategy of each associated building material, and the material association strength between the building material and each associated building material, identifying the target calling building materials when the building material is called, and the call sequence of each target calling building material; based on the call sequence of each target calling building material, adding the building material and the call information of each target calling building material to the building material associated call network to obtain initial dynamic control information of building materials, and adding the control and call strategy of each building material to the node corresponding to each building material in the initial dynamic control information of building materials to obtain dynamic control information of building materials.
[0096] In this embodiment, the terminal identifies the associated building materials corresponding to each building material based on the building material association call network, and for each building material, based on the building material control call strategy, the control call strategy of each associated building material, and the material association strength between the building material and each associated building material, identifies the target call building materials when the building material is called, and the call sequence of each target call building material. Specifically, the terminal first screens the call building materials corresponding to the association strength greater than the association strength threshold among the associated building materials of the building material, and then the terminal queries the same sub-control call mode (i.e., restricting and controlling the flow difference information, and restricting and controlling the call difference information) in the control call strategy of each call building material and the control call strategy of the building material, and identifies the proportion value of the same sub-control call mode in the control call strategy of each call building material to all the sub-control call modes in the control call strategy of each call building material. The terminal uses the call building material corresponding to the proportion value greater than the proportion value threshold preset in the terminal as the target call building material. The target call building material can ensure that when the building material is controlled and called, the target call building material is simultaneously called and controlled. Improved the accuracy and efficiency of control over all building materials.
[0097] The terminal calls the calling sequence of building materials based on each target, adds the building materials and the calling information of the building materials called by each target in the building material associated calling network, obtains the initial dynamic management and control information of building materials, and adds the control and calling strategy of each building material to the node corresponding to each building material in the initial dynamic management and control information of building materials, to obtain the dynamic management and control information of building materials.
[0098] Based on the above scheme, this scheme combines the constructed building material association call network and the management and control call strategy of each building material to comprehensively carry out dynamic management and control information of each building material, so that it can ensure the comprehensive management and control of all building materials in the supply chain, while ensuring the efficiency and accuracy of management and control, and improving the management and control effect of each building material, thereby comprehensively improving the building material management and control effect of the supply chain platform.
