This document discusses optimization of industrial distribution networks based on small-world network models. It provides an overview of small-world networks and how they can be applied to industrial distribution. As a case study, it analyzes the industrial network structure in Chaoyang District, Beijing, looking specifically at high-tech manufacturing and software services industries. Key aspects analyzed include network structure, node characteristics, critical chains, and buffering. Small sub-networks are identified within the larger industrial network that demonstrate small-world network properties of local clustering and short path lengths.
