“…Examples of this work include empty rail car allocation for automobile shipments considering uncertain transit times and delivery priority (Sherali and Suharko, 1998), vehicle fleet allocation considering future demand uncertainty, vehicle ownership, multiple vehicle types, vehicle assignment to best fit demand, and penalties for late delivery (List et al, 2003), truck rental fleet sizing considering multiple time periods, multiple truck types, and multiple locations (Wu et al, 2003), and truck fleet sizing for disposition of radioactive waste under uncertain demand (List et al, 2006). The prior research focuses on mathematical programming formulations that can be solved to find an optimal fleet size.…”
