Abstract

Because of the severe consequences arising from Hazardous Material (HazMat) accidents, risk assessment concepts have become a necessary part in the management of HazMat logistics, especially for vehicle routing. Optimization is an effective technique and is often used in handling the HazMat logistics routing. This study aims to create a model to prepare a risk-based route network by prioritization technique. The outcome of which can be used in future work on route optimization. This research proposes a method to create an effective logistics network with HazMat-risk concern using the concept of Multiple Criteria Analysis (MCA) by Analytic Hierarchy Process (AHP). In the research, gasoline logistics was selected for detailed study as it was one of the most commonly transported HazMat in Thailand. AHP Structure carried out in this study is based on the judgments and comments of an expert group and local communities. The structure was divided into 3 main components—risk of carriage unit explosion, risk of road accidents and consequences of an incident. Regarding the explosion risk, characteristics of the carriage unit and quantity of HazMat are focused. For investigations of road accidents, contributory factors are considered. Two consequences were included in the study namely, the on-route and off-route population. A mathematical model, formulated by the criteria priority of each factor and its risk level was used for the prioritization. The results show that participants rank the risk of having a road accident as the top priority, followed by the risk of carriage unit explosion and the consequences of an incident (47.8%, 27.4% and 24.8% respectively). To examine this model, data for logistics of gasoline and diesel fuel in Rayong Province (Thailand) were used for the model application. From the calculation, it was possible to reduce the risk of road accidents and the consequences by approximately 6.8% and 38.5% respectively by choosing the best alternative route instead of the current one.
