Physics of Decision: managing and preparing critical supply chains to supply disruptions

Today, supply chains face many uncertainties and making well-informed decisions requires performant decision support systems and methods. The purpose of this study is to apply a new perspective of decision support: the Physics of Decision (PoD). This approach considers risks or opportunities (potentialities) as physical forces and which are assessed regarding their intensity and contribution towards or as deviations of the system's performance trajectory compared to a target. Such an evaluation permits studying the effect of different mitigation actions to support the decision-making process and prioritize corrective measures. The approach is applied to an aerospace manufacturing case study facing a supply shortage, a high stake in this sector.
