AI Technical Summary
Existing technologies in container trailer swapping mainly focus on the one-truck-one-trailer problem, lacking research on one-truck-two-trailers, resulting in insufficient optimization of transportation efficiency and costs, and underutilization of multi-trip transportation services.
By introducing multiple state variables, a nonlinear mixed-integer programming model is constructed, and through linearization, a linear mixed-integer programming model (SB-MILP) is formed to optimize the number of tractor-trailers and the trip length, thus solving the transportation problem of one vehicle with two trailers for multiple trips.
It improves the efficiency of container trailer swapping and transportation, reduces transportation costs, and reduces the number of vehicles used and fixed cost inputs by increasing the number of trailers and multi-trip transportation.
