Abstract: For the closed-loop supply chain system consisting of manufacturers, retailers and demand markets, entropy theory was used to quantify the brittleness of the closed-loop supply chain system as a whole, and it was studied that how, with the overall degree of brittleness of the closed-loop supply chain system exceeding the threshold, resulting in the collapse of the system, to weaken the brittle relationship between systems while reducing the overall brittleness of the system, so as to maintain the stability of the system. By analyzing the brittle structure and characteristics of the closed-loop supply chain system, the brittle propagation model was established, the hierarchical brittleness diagram of the system was obtained, and the brittle source of the closed-loop supply chain system was identified. The brittleness of the system was reduced from three aspects: the brittle source, the source of the brittle source, and the subsystem with the largest correlation with the brittle source. Through examples, it is shown that when the overall brittleness of the closed-loop supply chain system exceeds the system threshold, in order to avoid system crashes, the brittleness of the system is reduced through the treatment of brittle sources, thus improving the system.

Key words: closed-loop supply chain, brittle source, degree of brittleness, graph theory, entropy
