Description

Technical Field

[0001] The present invention relates to the field of logistics technology, and in particular to a material trajectory tracking method and system based on double-layer genetic information. Background Art

[0002] In today's complex global supply chain system, it is particularly important to achieve accurate and comprehensive material tracking throughout the entire chain, from the manufacturer at the source of materials, through the various levels of procurement distributors in the middle links, to the final delivery of materials to the consumer terminal. This is not only related to improving logistics efficiency and cost control, but more importantly, it provides a solid traceability safety net for the entire chain from material production to consumption, ensuring the reliability of product quality, effectively preventing the circulation of counterfeit and shoddy goods, protecting consumer rights, and responding to the growing trend of transparent consumption and social responsibility requirements.

[0003] However, most of the existing material tracking technologies and management systems focus on single-dimensional tracking methods such as serial number tracking and batch tracking of the product itself. Although these methods can achieve basic traceability functions to a certain extent, their limitations gradually become apparent when faced with the diversified and dynamically changing needs of the supply chain. Specifically, these traditional tracking methods often fail to meet the following key requirements:

[0004] Multi-dimensional screening and evaluation: Modern procurement systems require a comprehensive evaluation of material suppliers, including but not limited to supplier qualifications, historical supply quality, sustainability practices, etc. A single tracking mechanism is difficult to integrate these multi-dimensional information, making it difficult for procurement to conduct efficient and accurate comprehensive evaluation and screening when selecting suppliers and products.

[0005] Intelligent review and optimization of procurement plans: As supply chain management transforms towards digitalization and intelligence, the formulation and execution of procurement plans need to be more refined and flexible. Traditional tracking methods cannot provide real-time feedback on market changes, inventory status, and logistics dynamics, resulting in a lack of sufficient data support for procurement plans, making it difficult to adapt to rapidly changing market demands, and unable to achieve effective control of procurement costs and risks.

[0006] Supply chain transparency and collaboration: In a supply chain involving multiple parties, improving transparency and collaboration between links is the key to improving overall efficiency. A single tracking method limits information sharing between upstream and downstream supply chains, affects the timely discovery and resolution of problems, and is not conducive to building a supply chain ecosystem based on trust and cooperation.

[0007] Therefore, there is an urgent need to develop a new material tracking system that can not only achieve accurate tracking of individual materials, but also integrate information from all links in the supply chain, support multi-dimensional screening and evaluation, intelligent procurement plan review and optimization, and promote comprehensive, transparent and collaborative supply chains. This has become a technical challenge that needs to be solved urgently. Summary of the invention

[0008] The technical problem to be solved by the present invention is that the conventional material tracking method or system is a single tracking method or system based on product composition, which cannot simultaneously meet the multiple needs of the procurement system for screening material suppliers and products and reviewing the procurement plans of material users.

The material trajectory tracking method based on double-layer genetic information as claimed in claim 1, wherein: In step S4, the purchase priority calculation method of the replaceable products is: According to the purchased product number j, get the product relative gene chain j,1 .cou, based on product relatives gene chain j,1 .cou obtains the number of the product with the greatest performance similarity to the purchased product j, and records it as product j'; According to the purchased product j, obtain the purchased relative gene Using the historical purchasing information of products with similar performance, obtain the purchasing priority of manufacturers whose purchasing product number j can replace product j'; If Chain j',1 .chi=φ, then let the product performance analysis unit set If Chain j', 1. chi≠φ, then let the product performance analysis unit set Calculate the performance purchasing priority of the manufacturers of alternative product j'; Among them, if the replacement purchased product j' has a manufacturer with the highest performance purchasing priority, and the damage rate of the replacement purchased product j' and the average service life of the purchased product j' are better than the corresponding indicators of the manufacturer with the highest performance purchasing priority for the purchased product j, then the purchased product j is adjusted to the replaceable purchased product j'.

6. The material trajectory tracking method based on double-layer genetic information as claimed in claim 1, wherein: Step S5 includes: Set the purchase unit unreasonable consumption warning to like If the ratio is greater than the set threshold, it is determined that there is a possibility of unreasonable consumption by purchasing unit i; Num(J i ) represents the quantity of all product types purchased by the purchasing unit; Coefficient of determination The calculation method is: Load the purchasing usage gene of purchasing unit i purchasing product j And purchase the quantity of Brother Gene manufacturers The corresponding purchasing unit's purchased product j uses the gene Will and Sort in ascending order and get The serial number in the ordered sequence of average service life is denoted by Condition? Value 1: Value 2 is a conditional expression, which means that if the condition is met, the conditional expression takes the value 1, and if the condition is not met, the conditional expression takes the value 2; Calculate the unreasonable purchase warning degree of purchasing unit i as like If the ratio is greater than the threshold, the purchasing unit i is reduced in the unreasonable purchase product set. The purchase volume; Thres represents the idle time control threshold, t j Indicates the validity period of purchased product j.

7. The material trajectory tracking method based on double-layer genetic information as claimed in claim 6, wherein: In step S5, the method for calculating the unreasonable consumption warning degree specifically includes: like If the ratio is greater than the threshold, the purchasing unit i will be reduced in the unreasonable purchase product set. Purchase volume; Among them, Thres,t j They respectively represent the idle time control threshold and the validity period of purchased product j.

8. A material track tracking system based on double-layer genetic information, using the material track tracking method based on double-layer genetic information as described in any one of claims 1-7, wherein the material track tracking system based on double-layer genetic information has a product relationship diagram at the production end and a product relationship diagram at the procurement end, and the material track tracking method based on double-layer genetic information establishes a mapping of each product according to the product relationship diagram at the production end and the product relationship diagram at the procurement end, and obtains a material gene information chain at the production end and a material gene information chain at the procurement end; constructs the material gene information chain at the production end and the material gene information chain at the procurement end into double-layer genetic information of the material in the genetic algorithm; based on the double-layer genetic information of the material, calculates the performance procurement priority of the same product from different manufacturers and the performance procurement priority of replaceable procurement products according to the service life and damage rate of the product; Determine whether to use alternative products based on the performance purchasing priorities of different manufacturers of the same product and the performance purchasing priorities of alternative products; Set an early warning level for unreasonable consumption by purchasing units, monitor their consumption, and track the gene chain of purchasing units that exceed the early warning level for unreasonable consumption.
