Description

Technical Field

[0001] The present invention relates to the field of procurement management, and in particular to a raw material procurement management system based on a one-stop flexible supply chain. Background Art

[0002] Raw material procurement management is based on purchasing products. Through standardized processes such as fixed-point, pricing and ordering, the business relationship between the enterprise's product demanders and suppliers is established, and the content is gradually optimized. Raw material procurement management is also an important part of enterprise production. Traditional raw material procurement management still relies on manual operations, and even in most procurement processes, it is too dependent on manual processing, which can easily lead to a large information gap in the industry, and difficulties in the exchange of information on resources in the upstream and downstream industrial chains of the industry, and unstable industry inventory, such as the phenomenon of raw material backlog or shortage, which is not conducive to the long-term and steady development of the industry;

[0003] Therefore, it is particularly important to design a service platform that can focus on the industry's one-stop flexible supply chain in the development of the industry, and use the platform to empower upstream and downstream users, achieve information docking of upstream and downstream industrial chains, flexible employment, and risk control of raw material procurement and inventory;

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0005] In the present invention, the upstream and downstream industrial chains are connected through a one-stop flexible supply chain, so that manufacturers can timely learn about the supply information of upstream manufacturers and the demand information of downstream manufacturers, so as to allocate production speed and raw material supply. By analyzing the demand for goods of downstream manufacturers, the production speed that can meet the delivery time is obtained. By combining the logistics transportation time with the raw material supply, the dynamic model analysis method is adopted to analyze the raw material in and out behavior in the production process of the manufacturer, so that the manufacturer can reduce the warehouse inventory while ensuring sufficient raw materials, which not only ensures the manufacturer's ability to cope with production fluctuations but also avoids excessive raw material backlogs to increase the impact of market changes on manufacturers, so as to solve the technical defects proposed by the background technology.

[0032] Figure 2 It is a dynamic analysis model diagram of the present invention. DETAILED DESCRIPTION

[0033] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 2 As shown, a raw material procurement management system based on a one-stop flexible supply chain includes a procurement supervision unit, an information interaction unit, an inventory control unit, a risk control unit, an upstream information analysis unit and a downstream information analysis unit;

[0035] The upstream information analysis unit is used to obtain the production and supply information of the upstream manufacturers, and the downstream information analysis unit is used to obtain the commodity demand information of the downstream manufacturers, wherein the production and supply information includes the supply quantity and the supply time, and the commodity demand information includes the demand quantity and the pickup time;

[0036] The information interaction unit obtains the management link, where the management link is the production work performed by the purchaser, the upstream manufacturers supply raw materials to the production work performed by the purchaser, and the downstream manufacturers purchase products from the production work performed by the purchaser. The information interaction unit obtains the production and supply information through the upstream information analysis unit. When the upstream information analysis unit obtains the production and supply information of the upstream manufacturers, it records the production and supply information of the upstream manufacturers within multiple statistical periods, calculates the average value, obtains the average production and supply information within a statistical period, and records it as the average supply information, where the statistical period is preset by the management personnel according to the market change speed and experience;

[0037] The upstream information analysis unit sends the average supply information to the information interaction unit, and the downstream information analysis unit sends the average commodity demand to the information interaction unit. The commodity demand information is obtained through the downstream information analysis unit. When the downstream information analysis unit obtains the commodity demand information of the downstream manufacturers, the commodity demand information of the downstream manufacturers in one statistical period is recorded, and the commodity demand information in multiple statistical periods is averaged to obtain the average commodity demand information in one statistical period, and the average commodity demand information is recorded as the average commodity demand;

[0038] The information interaction unit obtains the average commodity demand and the commodity demand information of the current downstream manufacturers, and calculates the difference between the average commodity demand and the commodity demand information of the current downstream manufacturers, and records the result of the difference calculation as the commodity surplus value. When the commodity surplus value is a positive number, it indicates that the current commodity quantity is lower than the average commodity demand, and there may be a concentrated commodity demand and an increase in order quantity in the future, then a commodity reduction signal is generated; when the commodity surplus value is a negative number, it indicates that the current commodity demand is higher than the average commodity demand, and there may be a decrease in commodity demand and a decrease in order quantity in the future, then a commodity increase signal is generated, and the commodity reduction signal and the commodity increase signal are sent to the risk control unit.

[0039] The information interaction unit analyzes the production supply information and commodity demand information to obtain the commodity production speed allocation signal. The commodity production speed allocation signal obtained by the information interaction unit includes a speed satisfaction signal and a speed shortage signal. The information interaction unit obtains the demand quantity and pickup time in the commodity demand information with the closest time distance, and generates a minimum production speed based on the demand quantity and pickup time, and compares the minimum production speed with the current production speed. If the current production speed is greater than or equal to the minimum production speed, a speed satisfaction signal is generated. If the current production speed is less than the minimum production speed, a speed shortage signal is generated, and workers are recruited through a one-stop flexible supply chain to make the production speed meet the minimum production speed and ensure the temporary production capacity of the factory.

[0040] Example 2: Please refer to Figure 1 - Figure 2 As shown, the inventory control unit obtains inventory information and logistics transportation information, and sends the inventory information and logistics transportation information to the risk control unit, wherein the logistics transportation information is the commodity transportation time. After the inventory control unit obtains the logistics transportation information and the delivery time of the production supply information, it calculates the arrival date of the raw materials provided by the upstream manufacturer according to the commodity transportation time and delivery time in the preset logistics transportation information, and sends the arrival date and arrival quantity of the raw materials provided by the upstream manufacturer to the risk control unit;

[0041] The risk control unit obtains commodity demand information, production and supply information, inventory information, and logistics and transportation information through the information interaction unit, analyzes the above information, generates risk control signals based on the analysis results, and sends the risk control signals to the procurement supervision unit to remind the procurement supervision unit of procurement;

[0042] The information interaction unit calculates the start time of commodity production and the consumption of raw materials for this batch of production according to the pickup time in the commodity demand information and the production speed of the manufacturer. The information interaction unit sends the start time of commodity production and the consumption of raw materials for this batch of production to the risk control unit. After the risk control unit obtains the commodity demand information, it calculates the quantity of raw materials required to produce the quantity of commodities according to the commodity demand information. The information interaction unit obtains the quantity of raw materials in the inventory information. The information interaction unit obtains the quantity of raw materials in the production supply information, and dynamically balances the production supply information and the inventory information by means of dynamic analysis.

[0043] The method for the risk control unit to perform dynamic analysis is:

[0044] S1: Obtain the quantity of raw materials required for commodity production in commodity demand information, the quantity of raw materials in production supply information, and the quantity of raw materials in inventory information, and generate a production module and an inventory module for dynamic analysis;

[0045] S2: Sort the raw material arrival dates and product production start times provided by upstream manufacturers in chronological order, mark the arrival quantity and raw material consumption for each production in the sorting, record them as the active raw material change line, and connect the active raw material change line to the production module;

[0046] S3: Input the production raw material consumption and arrival quantity in the active raw material change line into the production module in chronological order. When the raw material quantity in the production module is insufficient, input the raw material into the production module through the inventory module;

[0047] S4: The inventory module counts the quantity of raw materials in the inventory information and records it as the material backlog quantity M. If the material backlog quantity M is greater than the preset material backlog quantity upper limit M0, a material excess signal is generated. If the material backlog quantity M is less than the preset material backlog quantity lower limit M1, a material shortage signal is generated. When the risk control unit obtains a commodity reduction signal, the upper limit of the material backlog quantity used is M0a, and the lower limit of the material backlog quantity used is M1a. When the risk control unit obtains a commodity increase signal, the upper limit of the material backlog quantity used is M0b, and the lower limit of the material backlog quantity used is M1b, where M0a>M0b, M1a>M1b;

[0048] The procurement supervision unit obtains the risk control signal through the information interaction unit and generates a procurement signal based on the risk control signal, wherein the risk signal is divided into an excess material signal and an insufficient material signal. The procurement signal is a reminder signal to prompt management personnel to make purchases. The inventory module sends the excess material signal and the insufficient material signal to the procurement supervision unit. After the procurement supervision unit obtains the excess material signal, it reduces the amount of raw materials purchased from the production and supply information of the upstream manufacturers. After the procurement supervision unit obtains the insufficient material signal, it increases the amount of raw materials purchased from the production and supply information of the upstream manufacturers.

[0049] In the present invention, the connection between the upstream and downstream industrial chains is achieved through a one-stop flexible supply chain, so that manufacturers can timely learn about the supply information of upstream manufacturers and the demand information of downstream manufacturers, so as to allocate production speed and raw material supply. By analyzing the demand for goods of downstream manufacturers, the production speed that can meet the delivery time is obtained. By combining the logistics transportation time with the raw material supply, the dynamic model analysis method is adopted to analyze the raw material in and out behavior in the manufacturer's production process, so that the manufacturer can reduce the warehouse inventory while ensuring sufficient raw materials, which not only ensures the manufacturer's ability to cope with production fluctuations but also avoids excessive backlog of raw materials and increases the impact of market changes on the manufacturer.
