YARD WAITING DEMURRAGE TIME PREDICTION DEVICE, METHOD AND PROGRAM

摘要

To enable the prediction of an expectation value of a yard waiting demurrage time in landing articles transported by using a transport ship at an unloading point.SOLUTION: In the case where the amount obtained by adding a prediction object period start total stock in a yard of an unloading point and an unloading amount total (hereafter, the unloading amount total is called as an arrival amount) of a transport ship that arrives during a prediction object period exceeds the capacity of the yard, a yard waiting demurrage time prediction device 100 calculates an expectation value of a yard waiting demurrage time by integrating a function obtained by multiplying a formula of a prediction model by the occurrence probability of the arrival amount per predetermined unit time with respect to the arrival amount by using the prediction model that yard waiting demurrage occurs as much as a time obtained by dividing an excess by a used amount of the prediction object period.SELECTED DRAWING: Figure 1
