Route Optimization Of Container Trucks Outside The Port Based On Reservation Feedback Mechanism

The development level of port logistics represents whether a city is competitive or not,with the development of economic globalization and the rapid development of China’s economy.However,container transportation is the key means of developing port logistics.The arrival of a large number of container trucks during the peak period may cause port congestion and reduce the efficiency of the terminal.Therefore,reducing congestion at the gates and improving transportation efficiency have become pressing issues.Based on the above research background,this thesis decides to take the container truck outside the port as the research object,and mainly focuses on the path of the container truck to pick up and place the container outside the port of the freight station and the container terminal.Predict the travel time between the station and the container terminal,and establish a container truck outbound route optimization model based on the reservation feedback mechanism for the shortest time required for the container truck fleet to complete the transportation task;by establishing a container truck reservation system at the door,not only consider the container According to the time period and reservation share of the truck reservation,the terminal reservation system will retrieve the reservation information and container stacking information,and feed the information back to the container truck driver to form a reservation feedback mechanism.Finally,this thesis designs an algorithm and analyzes the results against each other.In order to verify the validity of the model and algorithm,a hybrid heuristic algorithm based on genetic algorithm and simulated annealing algorithm is used to solve the collector path optimization model,and a reasonable transportation plan was formulated,and the solution results were compared with the traditional transportation plan.The experimental results show that the hybrid heuristic algorithm solves faster and has better solutions,and the hybrid heuristic algorithm is feasible to a certain extent.The establishment of the reservation feedback mechanism can enable the two-way flow of information,reduce the waiting time of container trucks at the gate and the yard,significantly increase the work efficiency of container trucks,and also improve the internal operation efficiency of the terminal.Therefore,this thesis can provide a new idea for route optimization in gathering and distribution port operations and improving the efficiency of terminal operations.
