Abstract: An important factor affecting the performance of a supply chain (SC) is the severity of the disturbance to the chain. The performance measures of the chain could be expected to be adversely affected by an increase in the severity of the disturbance to the system, while a system with a less severe disturbance could be expected to show better performance under the same set of circumstances. And thereby the severity of the disturbance becomes a quantity of fundamental interest in measuring SC performance. To this end, this paper proposes a substantially new quantitative definition and measure of the severity of a disruption or disturbance to a SC, through the dynamic modelling framework. The measure is then illustrated for various types of disturbances. The measure proposed herein could be expected to be of a fundamental nature, and of significance in studying the responsiveness, resilience, and operational performance analysis of SCs.

Keywords: disruption; disturbance to a supply chain; severity of a disturbance; quantitative measure; quantitative definition.
