Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent warehouse for material management, and relates to a full life cycle management method and system for visualized material circulation. Background Art

[0002] The current circulation process of communication installation and maintenance materials is long and the cycle is long, involving multiple links and roles. The closer to the end link, the more significant the multidimensionality, dynamics and hysteresis of the data, which causes many uncertainties in management and future decision-making.

[0003] The circulation process of communication installation and maintenance materials involves communication enterprises, material suppliers, third-party personnel, renovation companies and end users, and different departments are involved in the enterprise. The current difficulties are that material procurement is based on historical experience data rather than actual needs, material distribution is manually reported rather than business needs, material use is based on personal habits rather than user needs, and material renovation and reuse rely on personal consciousness. There is a lack of a full life cycle management system for the visualization of communication material circulation to achieve visualization, management and control of material procurement, distribution, use, renovation and other processes.

[0004] The main process of the existing technical solution includes four core links: procurement-distribution-use-refurbishment. The overall process is static, manual and decentralized. In the procurement process: the company makes annual or quarterly demand forecasts based on past usage records and experience data, and collects the reporting needs of various departments; the procurement plan is approved by the management to determine the type, quantity and budget of the purchased materials, and the purchase order is completed by manually connecting with the supplier. The supplier prepares the goods according to the order and arranges the delivery.

[0005] In the distribution stage: installation and maintenance personnel collect materials from the warehouse or personal inventory according to task requirements and record their usage. After receiving the materials, the installation and maintenance personnel manually record the material usage information, including purpose, task number and remaining inventory.

[0006] In the renovation and recycling stage: the installation and maintenance personnel must actively report the recycling application for the waste materials, and then recycle them to the warehouse for renovation. The warehouse classifies the recycled materials into categories: those that can be refurbished, those that need to be disassembled and recycled, or those that are scrapped. The refurbished materials are sent to professional renovation agencies for processing, and the progress of the task is tracked manually.

[0007] The data of each link are recorded by the procurement, warehousing, logistics and renovation departments respectively, and the data are scattered and not linked. Procurement lacks scientific basis: the material procurement plan relies on historical experience data, and does not combine actual demand and business forecasts, resulting in inventory backlogs or shortages. Inefficient distribution: material distribution is completed through manual reporting, lacking dynamic demand adjustment and logistics optimization. Unstandardized use: the use of materials mainly depends on the personal experience of installation and maintenance personnel, resulting in unreasonable configuration or waste of resources. Delayed renovation and reuse: renovation management relies on manual reporting, with low recycling efficiency and under-utilization of reused resources. Summary of the invention

[0008] The purpose of the present invention is to provide a full life cycle management method and system for visualized material flow, reduce surplus or shortage caused by information delay or insufficient demand forecast, and improve the efficiency of material refurbishment and reuse.

[0009] In order to achieve the above object, the basic scheme of the present invention is: a material flow visualization full life cycle management method, comprising the following steps:

[0010] The management system receives demand feedback from branches and, combined with historical usage data, calculates the purchase quantity for purchase orders;

[0011] Based on supplier qualifications, average transaction time data of historical transactions, and credit rating information, sort the supplier qualifications, average transaction time data of historical transactions, and credit rating information of each supplier, select the best supplier, send a quotation request to it, obtain price and supply cycle feedback to generate an electronic contract, and monitor the supplier's supply progress in real time;

[0012] Limit the autonomous purchasing authority of branches and approve purchase demand orders step by step according to preset rules;

[0013] After the supplier delivers the materials, the automated warehousing system starts, completes the material entry registration, generates electronic labels, and records the material number, entry time, and batch information;

[0014] According to the mission requirements and geographical location of the branch, classify by branch and material type to generate a distribution plan, and mark the branch's geographical location;

[0015] The installation and maintenance personnel of the branch office scan the material labels through the mobile application, register the task number, usage location and consumption quantity of the materials, synchronize the real-time data to the central database, and record the material usage data;

[0016] After completing the task, the installation and maintenance personnel submit a recycling application for the disassembled equipment and the image of the equipment to the management system. After receiving the recycling application, the management system determines the recycling priority of the equipment based on the equipment image and performs corresponding processing.

[0017] The working principle and beneficial effects of this basic solution are as follows: This technical solution realizes the full life cycle management of the circulation of communication installation and maintenance materials, including the visualization and intelligence of the procurement, distribution, use and renovation processes. Dynamically adjust the material procurement and distribution plan to reduce the surplus or shortage caused by information delays or insufficient demand forecasts. Through the renovation priority classification, the recycling priority is automatically judged to improve the efficiency of material renovation and reuse, and through standardized processes and data support, optimize resource reuse.

[0018] Further, the purchase quantity Q is calculated as:

For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0060] The present invention discloses a method for visualizing the whole life cycle management of material circulation, realizing the whole life cycle management of communication installation and maintenance material circulation, including the visualization and intelligence of procurement, distribution, use and renovation processes. It dynamically adjusts material procurement and distribution plans, reduces surplus or shortage caused by information delay or insufficient demand forecast, improves the efficiency of material renovation and reuse, and optimizes resource reuse through standardized processes and data support.

[0061] like Figure 1 As shown in the figure, the whole life cycle management method of material flow visualization includes the following steps:

[0062] The management system receives demand feedback from branches and, combined with historical usage data, calculates the purchase quantity for purchase orders;

[0063] In the supplier management module, select qualified suppliers, sort the supplier qualifications, average time consumption data of historical transactions, and credit rating information of each supplier based on supplier qualifications, average time consumption data of historical transactions, and credit rating information (the first dimension is: use supplier qualifications and credit ratings to sort and take the top ranking; the second dimension is: the shorter the average time consumption of supply transactions in historical transaction data, the higher the ranking), select the best supplier, and send a quotation request to it to obtain price and supply cycle feedback. The contract management module automatically generates an electronic contract (1. Design a contract template according to business needs, including fixed content and variable content (such as information of Party A and Party B, contract amount, time, etc.); 2. Complete the filling of specific contract content by online filling or automatic generation; 3. Generate PDF electronic contract content on the server side, send the electronic contract to the signatory, and both parties complete the signing through digital signature or electronic seal), and start supplying after the supplier confirms; through the supply tracking module, monitor the supplier's supply progress in real time. The estimated delivery time is 7 days. The system will update the status of the materials and notify the warehouse system in advance to prepare for receipt.

[0070] Q=D+SI

[0071] Among them, D is the expected demand, S is the safety stock, and I is the current inventory.

[0072] In a preferred embodiment of the present invention, according to the task requirements and geographical location of the branch, the optimal distribution route is generated based on the logistics optimization algorithm (mainly based on the distance d provided by the map service, with the shortest total path as the goal. When all demand points (branches) are visited, starting from the warehouse, passing through all demand points in sequence and returning to the warehouse, a route with the shortest total path distance or total time is solved. First, data preparation is performed, the geographical information of the branch is collected, and a distance matrix is ​​formed. The nearest neighbor algorithm is used, starting from the starting point (warehouse), and the nearest unvisited point is selected each time; the above steps are repeated until all demand points are visited and finally return to the starting point. According to the algorithm results, the optimal path is generated, and the total driving distance and estimated time are calculated) to calculate the optimal distribution path and generate a distribution plan:

[0073]

[0074] Among them, d ij is the distance from point i to point j. Assuming point i is the starting point, calculate the distance to each other point and take the minimum value; n is the number of points;

[0075] Route selection follows the principles of lowest cost and shortest time, and vehicles are dispatched to complete delivery.
