The 21st century is a century of complexity and networking.People try to analyze and explain various complex phenomena with the help of network theory,and design effective control schemes to optimize and manage complex systems at the same time.In reality,supply chain is such an example.Since most supply chains have a certain network structure,the study of various problems in supply network is closer to the reality from the perspective of network theory.This paper summarizes and analyzes the development of related researches by combing previous results.At the same time,some problems of supply chain network are discussed,which lay a foundation for further research.
