Truck and Trailer Routing Problem under fuzzy environment

The Truck and Trailer Routing Problem, TTRP, is an extension of the well-known Vehicle Routing Problem. This problem consist of a heterogeneous fleet composed of trucks and trailers to serve a set of customers. Most of models used in the literature assume that the data available are accurate, but in many practical problems the available knowledge about some data and parameters of the model in-volving uncertainty. In this study, we propose the application of a Soft Computing-based method to model and solve TTRP when the set of constrains is imprecise
