Stochastic Drayage Scheduling Considering Uncertainty in All Processes of Drayage Operations

This paper addresses the stochastic version of the drayage scheduling problem with time constraints at marine container terminals imposed by the truck appointment system and time constraints at customer locations. It develops two new models that considered time uncertainty in all processes of drayage operations without making an explicit assumption about each process duration’s underlying probability distribution. The first model assumes that the mean and variance of each process’s duration are available. The second model assumes that the mean as well as the upper and lower bounds of each process’s duration are available. Experimental results indicated that drayage operation time increases when the mean and variance of any process’s duration increase. Drayage operation time also increases when the difference between the upper and lower bounds of a process’s duration increases. Results also show that as the user-specified confidence level increases, so will the drayage operation time and percentage of feasibility. Lastly, results indicate that the deterministic model has a lower percentage of feasibility compared to the developed stochastic models.
