Vehicle Dispatch Problem with Precedence Constraints for Marine Container Drayage

Abstract

CO2 occupies over 90% of artificially emitted the Greenhouse Gas (GHG). As related in CO2 emission from road traffic, we focus on a vehicle routing for marine container transport. There are three container conditions: inbound trip, outbound trip and empty condition. And also there are two situations for vehicles: trailer truck (with full or empty container loaded) and empty truck (as tractor only). In this study, we address the tractor head assignment to trailers (chassis) with full/empty container with considering the precedence constraints for visiting customers, as to minimize CO2 emissions. As the computational results, there are around 25 % reductions of CO2 emissions in our proposed MIP model.
