Assessing the resiliency and importance of a supply chain network Conference Paper uri icon

abstract

  • In supply chain management under disruption, definition of resilience is based on many factors, and a consensus is yet to be agreed upon. In addition, there is very limited quantitative research in the supply chain resiliency field. Therefore, we propose a mathematical formulation for constructing a resilient supply chain under disruption. Our goal is to design supply chain networks that are resilient under stress by incorporating the concept of node importance. For quantifying resilience, mathematical formulation is a new approach, and the objective function of the model is based on the idea of resiliency triangle and node importance. Solving this problem, allows evaluation of the resiliency of a supply chain as a whole, as well as the resilience of individual building blocks. Disruptions and recovery are stochastic processes in real life. The problem itself has non-polynomial many binary variables. Therefore, we have developed a simulation model for validating the mathematical model. Many realistic scenarios have been generated and the simulation model has been tested under those scenarios.
