Abstract
In a complex environment, how to construct a resilient supply chain network (SCN) that can resist disruptions is a problem of great concern in supply chain management. In order to provide some insights for constructing a resilient SCN, this paper studies the influence of network structures on SCN resilience from the perspective of complex networks. Considering the exit and reselection of enterprises that have been ignored in previous studies, we propose a new SCN model in which nodes are connected with each other based on degree, fitness and distance. Subsequently, different disruption scenarios are simulated and the resilience of the SCN generated by the proposed model is compared with that of previous models. The simulation results show that the SCN generated by the proposed model is resilient to random disruptions, but vulnerable to targeted disruptions. In particular, the resilience of the SCN will be seriously affected when the strong-strong alliance is broken. Through the research on the influence of the parameters (e.g., α, β and f) of the proposed model on SCN resilience, we find that α has a significant impact on SCN resilience. The larger the value of α is, the worse the resilience of the corresponding SCN is. The parameter β has a slight effect on SCN resilience, and the more uniform the distribution of f in the network is, the better the resilience of the corresponding SCN is. This study may contribute to the design and resilience optimization of SCNs.
Highlights
With the development of globalization, a supply chain system has gradually evolved into a huge and complex system, in which the cooperation between enterprises has formed a complex supply chain network (SCN) [1]–[2]
In an increasingly turbulent and complex environment, SCNs are exposed to various disruptions, such as earthquakes, floods, and terrorist attacks, which will affect the normal operation of SCNs and even cause serious economic losses [3]–[6]
RELATED WORK This paper mainly studies the impact of network structures on SCN resilience under different disruption scenarios
Summary
With the development of globalization, a supply chain system has gradually evolved into a huge and complex system, in which the cooperation between enterprises has formed a complex supply chain network (SCN) [1]–[2]. This paper studies from the perspective of complex networks, regarding enterprises as nodes and cooperative relationships as edges. This paper will fully consider different disruption scenarios and study the influence of network structures on SCN resilience, so as to provide some insights for building a resilient SCN. This study contributes to the existing literature by filling in the following research gaps: (i) the exit and reselection of enterprises that have been neglected in previous studies are considered in this study when modeling an SCN; (ii) node degree, fitness and distance are considered simultaneously in the connection rules of the SCN model; and (iii) different from previous studies, different disruption scenarios are fully considered in this study, including different disruption types and objects.
