Impact of a disruption in a supply chain: An assessment model

This paper aims to propose a model for the evaluation of the economic impact caused by a disruption of a supply chain. The model evaluates the impact on companies (nodes) upstream and downstream after identifying disrupted nodes. The impact on individual nodes is calculated in terms of Business Interruption (representing the number of days that the node does not generate value) and the turnover produced by the node. The paper describes the main operating logics of the model and the method used for their verification and validation. The work was developed using the anylogic simulation tool.
