ヤード管理装置、ヤード管理方法およびコンピュータプログラム
Document Type and Number:
Japanese Patent JP5365759
Kind Code:
B1
Abstract:
By using, as decision variables, an initial transfer time (k_it_[i]) ⋅ a final transfer time (k_ft[i]) of each of transfer target steel materials (lots) i including materials to arrive and already arriving materials, a transfer constraint expression regarding the transfer order of the transfer target steel materials (lots) i and a transfer objective function for minimizing the time during which the transfer target steel material (lot) i stays in a course of being transferred to a main pile are expressed, and optimum values (k_itopt[i], k_ftopt[i]) of the initial transfer time ⋅ the final transfer time of the transfer target steel material (lot) i are derived so that the transfer objective function JA is minimized within a range satisfying the transfer constraint expression.
