Layout Optimization of Yard Template Plan Considering Vessels’ Operational Time Requirements

In order to solve the problem of delayed departure of vessels in container ports and improve the efficiency of yard operation, a mathematical programming model of yard template planning based on vessels’ operation time was proposed to optimize the number of vessels loading points and put the operation time of vessels into constraints to avoid delayed departure of vessel. At the same time, transportation distance is put into the objective function to minimize transportation cost of containers. The numerical experiments are designed, which is solved by CPLEX solver to verify the validity of the model. The experimental results show that the mathematical model can deal with the problem of delayed departure of vessel.
