In this paper we define a new problem, the aim of which is to find a set of k dissimilar solutions for a vehicle routing problem (VRP) on a single instance. This problem has several practical applications in the cashin-transit sector and in the transportation of hazardous materials. A min–max mathematical formulation is proposed which requires a maximum similarity threshold between VRP solution...

Road selection for hazardous materials transportation relies heavily on risk analysis. With risk being generally expressed as a product of the probability of occurrence and the expected consequence, one will understand that risk analysis is data intensive. However, various authors have noticed the lack of statistical reliability of hazmat accident databases due to the systematic underreporting ...

An approach to formalize and solve a decision problem related to the management of fleets that transport dangerous goods through a critical infrastructure is here presented. The model introduced takes into account the presence of different decision makers, each of which has access to a specific (partial) information set about the state of the entire system. The problem is also characterized by ...

Spill fires usually occur during the storage and transportation of hazardous materials, posing a threat to the people and environment in their immediate proximity. In this paper, a classical Quantitative Risk Assessment (QRA) method is used to assess the risk of spill fires. In this method, the maximum spread area and the steady burning area are introduced as parameters to clearly assess the ra...

In China, the Ministry of Transport stressed need to “Strengthen application active safety technology”. The transportation hazardous chemicals represented by LNG, LPG, and liquefied hydrocarbons is weak link in traffic safety. aim this study apply digital twin (hereinafter referred as DT) technology whole process handling (including loading unloading) help improve anti-risk ability road network...

Intermodal transportation has experienced a phenomenal growth over the past two decades, and continues to be one of the rapidly growing segments of the transportation industry. This has been attributed to the competitive pressures on global supply chains, the increasing demand for new service patterns driven by ocean carriers as well as the globalization of industry (Szyliowicz, 2003; Stone, 19...
