Supply chain safety management method based on multilevel analysis

The invention discloses a supply chain safety management method, device and equipment based on multilevel analysis. Comprising the steps that a supply chain layered structure is established, the layered structure comprises A-level elements and B-level elements, and the B-level elements are subordinate elements of the A-level elements; constructing an initial supply chain judgment matrix; performing consistency verification on the initial supply chain judgment matrix; weight values of the A-level elements and the B-level elements are calculated, and the safety level of the supply chain is determined; and screening out elements with low security levels, and giving a security alarm. Multi-aspect and multi-angle supply chain management can be realized based on a multi-level analysis method; judgment is carried out through consistency verification, additional investment is not needed, and the supply chain management cost of an enterprise is reduced; by giving an alarm to the element with the low security level, th
