Abstract: Disruptions in supply chains (SC) force the professionals globally to ponder on alternate procurement strategies to remain profitable. In this study, we consider a two-stage supply chain network, with an objective to study the feasibility of different procurement strategies with the objective of maximising profit. System dynamics (SD) modelling has been used to model and simulate the supply chain design system. The article starts with a literature review on supply chain disruptions and alternative strategies, followed by a case of an enterprise facing SC disruption. Various scenarios are simulated and analysed using SD. The simulation results are expected to provide the organisation an insight into the effects of using alternative procurement strategies. Further, it is expected to add to the body of knowledge in SC disruptions and provide a new methodology to study the behaviour of various procurement strategies for small-scale firms.

Keywords: supply chain network design; disruption; system dynamics; procurement strategies.
