In this paper, we introduce models for the optimization of the door-to-door freight transportation. The main thrust of these models stand in the allowance to forecast of freight amounts that will be transported daily considering capacity as well as time constraints (e.g. time availability of retailers and customers). We also have integrated real-world constraints to meet practical difficulties that may actually face transportation (e.g., fixed number of working hours of drivers, availability of vehicles). The transportation scheme is characterized by a consolidation center. We assumed, also, that freight transportation is mutualized. Thus, we have split the FDPTW (Pickup and Delivery Problem with Time Windows) into two problems: (i) is a Vehicle Routing Problem with Time Windows (VRPTW) with Pickup; (ii) is a VRPTW with Delivery. The proposed models are solved by LINGO. The output results are the optimal trucks in each model. Lastly, one of the elaborated models (VRPTW with delivery) is tested with Solomon's benchmark and for the other models we propose different numerical experiments to validate our contributions.
