This paper considers a VRP with soft time windows and fuzzy demand (VRPTWFD). The objective is to minimize both the total distance covered by all vehicles as well as the sum of lateness at the customerpsilas due to the violation of time windows. This VRPTWFD is formulated as a two stages recourse model in the context of stochastic programming. The goal is then to minimize the expected cost, which...
We analyze the task of selecting the most reliable units within a fleet of vehicles and formulate it as a prediction and classification problem. The prediction of each unit's remaining life is based on the identification of "peer" units, i.e. vehicles with similar utilization and maintenance records that are expected to behave similarly to the unit under consideration. With these peers,...
