Combinational Disruptions Impact Analysis in Road Freight Transportation Network

The impacts of disruption caused by transportation breakdown cannot be underestimated as this condition often hinders the actual logistic delivery. Thus, a contingency plan is absolutely necessary. In doing so, some managers propose a strategy to minimize time loss and cost inefficiency. This paper investigates the impacts of combinational disruption in a road freight transportation network. This paper uses the VRPTW model that describes the road freight transportation network. Two kinds of disruption scenario were observed in this model; a single disruption and a combinational disruption. The disruption impact analysis aims to uncover the effects of disruption on transportation cost. The results show that an optimal route strategy that provides minimal cost, which is computed by a numerical experiment, results in route effectiveness under each disruption scenario.
