Description

Technical Field

[0001] The present invention relates to the technical field of fastener material production management, and in particular to a fastener material flow supervision method and system based on a cloud platform. Background Art

[0002] Inventory management includes the storage, inventory and recording of inventory information. Generally, the storage of goods must follow certain rules, and inventory is to regularly check the goods in the warehouse to determine whether the actual inventory quantity is consistent with the book inventory quantity. In addition, the recording of inventory information is crucial. It is the basis of the entire warehouse management. By recording the time, quantity, storage location and other information of the goods entering and leaving the warehouse, dynamic monitoring of inventory can be achieved; fastener materials are a type of mechanical parts used to connect and fasten two or more components.

[0003] At present, traditional fasteners in the industrial field are standard auxiliary materials, which are characterized by concentrated categories and frequent repeated use. In daily use, problems such as material shortage, waste, and stagnant materials often occur, which poses specific problems and risks for the collection, use, and storage of materials by enterprises. In the storage management of fastener materials, data entry mainly relies on manual work. For example, after receiving or shipping goods, warehouse managers may not be able to enter data into the system in time due to busyness and other reasons. This results in inventory data not being able to reflect the actual inventory situation in real time. If there is an urgent order that needs to be shipped, there may be a shortage or oversold situation due to inaccurate inventory data.

[0004] At the same time, when the warehouse communicates with other departments such as the production department, the information transmission speed is slow because the management is mainly through paper documents or telephone. For example, it may not be possible to understand the minimum safety stock of inventory in time, resulting in failure to replenish stocks in time. The production department may also promise customers an unachievable delivery date because it cannot obtain inventory information in time, which brings cost and efficiency obstacles to the company's production management.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0006] In response to the problems in the related technology, the present invention proposes a fastener material flow supervision method and system based on a cloud platform to overcome the above-mentioned technical problems existing in the existing related technology.

[0007] The technical solution of the present invention is achieved in this way:

[0022] According to the sampling quantity n, the sampled materials are weighed by the weighing sensor respectively to determine whether the weight of the sampled materials meets the preset weight range threshold. If the weight of the sampled materials does not meet the preset weight range threshold, it means that the current sampled materials are defective, and the sampled defective quantity nc is obtained;

[0023] Get the defective rate p of the purchased materials, expressed as: P = (nc / n) × 100%, and if the defective rate p < the preset defective threshold, it means that the currently purchased materials meet the production requirements, complete the material warehousing and update the material inventory W c .

[0024] Wherein, the material consumption forecast value Y is obtained c , including the following steps:

[0025] The linear function of the calibrated material consumption y and production output x is expressed as: y = a + bx;

[0026] Among them, a is the intercept and b is the slope.

[0027] Calculate the value of a, expressed as:

[0028] Calculate the value of b, expressed as:

[0029] Among them, (x i ,y i ) are multiple sets of material consumption data under different production outputs, and are the average values ​​of production output x and material consumption y respectively;

[0034] The project management module generates a consumption list according to production requirements and sends the consumption list to the procurement management module to request material shipment;

[0035] The supply management module is used to receive the replenishment list in real time and complete the delivery according to the replenishment list.

[0036] Furthermore, the procurement management module includes: a warehouse entry detection module and an inventory warning module, wherein;

[0037] The warehousing detection module is used to detect the defective rate of the currently purchased materials. If the defective rate p is less than the preset defective threshold, it means that the currently purchased materials meet the production requirements, the materials are put into the warehouse and the material inventory W is updated. c ;
