A method, device and system for realizing supply chain reverse traceability

Abstract

The invention relates to the field of oil import and export and discloses a method, device and system for realizing the reverse retrospect of a supply chain. The method includes the first step of obtaining a transaction information identifier of illegal cargoes, wherein the transaction information identifier includes a transaction date and cargo information, the second step of identifying the transaction information identifier of the illegal cargoes to obtain the transaction date of the illegal cargoes and the cargo information of the illegal cargoes, the third step of obtaining at least one transaction document which proves that the transaction date is before the transaction date of the illegal cargoes and the cargo information contains the illegal cargoes according to the transaction date of the illegal cargoes, wherein the transaction document contains the transaction date, the cargo information and supplier information, and the fourth step of matching out a first transaction document with the earliest transaction date from at least one transaction document, obtaining the supplier information in the first transaction document to determine an illegal supplier. Through the method, automatic retrospect of illegal exported cargoes can be achieved, and the illegal supplier can be quickly and accurately found.

Description

technical field [0001] The invention relates to the field of oil import and export, in particular to a method, device and system for realizing reverse traceability of a supply chain. Background technique [0002] The REACH regulation is the European Union's regulation for the preventive management of all chemicals entering its market. This regulation came into effect on June 1, 2008. The REACH regulation adopts the precautionary principle of "no data, no market, no registration, no sales", and requires that all chemicals whose annual output or annual import volume exceeds 1 ton can only be produced and sold in the EU through registration. Strict data requirements and high registration costs have caused many non-EU downstream SMEs to abandon self-registration and instead choose to rely on upstream companies that have completed the registration process. Facing the complex export channels of downstream products to Europe, after the upstream refining and chemical enterprises h...
