Although operations research (OR) and constraint programming (CP) have different roots, the links between the two communities have grown stronger in recent years. For solving combinatorial optimization problems, the techniques of CP and OR will become so interdependent that the two research communities could eventuall…

Abstract System dynamics models, as causal models, are much like scientific theories. Hence, in evaluating such models, we assume certain norms of scientific inquiry. Most critics hold that the system dynamics approach does not employ formal, objective, quantitative model validation tests. This article argues that thi…

Climate change is among the top global risks due to its growing adverse impact on businesses. However, few empirical studies address this imminent risk from a supply chain perspective. Due to a lack of established approaches for capturing complex interaction between climate change risk and supply chain performance, a…
