Supply chain networks evolving model based on local economy regions

A Novel Supply Chain Network Evolving Model Under Random and Targeted Disruptions

“…Existing models either focus on the structure of the SCN and ignore the structural robustness (e.g., Refs. [21,63]), or neglect the real-world features of SCNs (e.g., Refs. [29,35]).…”

“…In our model, nodes represent firms in supply chain networks, and edges between nodes represent exchange relationships (e.g., business collaboration). We develop the BA model for the supply chain network, which is called the supply chain network evolving model, i.e., the SCNE model, by focusing on the phenomenon of regional economy [63], and the factor of firms' attractiveness [21].…”

“…Within the region, there is greater mobility of labor and capital [65][66][67]. (b) From the operational level, to cut down on transportation costs as well as to boost the synergy effect and share efficiency across partnerships [63]. (c) Organizations for regional economic cooperation exist, including the EU, APEC, FTAA, AFTA, and others.…”

“…In our model, we consider the locality preference i.e., the new node prefers nodes in its neighborhood over distant nodes [22,23,63] to capture the features of the SCN with the regional economy when firms are establishing cooperative relations. This characteristic is reflected in Eq.…”
