    Abstract: A movement range of each transfer vehicle (18) is determined and input (step S1). Assuming failure of one of the transfer vehicles (18), the movement range of the remaining transfer vehicles (18) is determined and input (step S2). The state of each transfer vehicle (18) is judged (step S3). If all the transfer vehicles (18) are normal, the movement range determined in step S1 is applied (step S4) and if any one of the transfer vehicles (18) has failed, the movement range determined in step S2 is applied. A carrying−out origin and a carrying−in destination of the transfer vehicle (18) are determined (step S6) and the transfer route is searched for (step S7). After this, searched route candidates are listed (step S8), the transfer route is corrected so as to be a rational route (step S9), and the transfer time is calculated for each of the route candidates (step S10). The transfer route of the shortest transfer time is selected and a branching device (22) is reserved so as to prevent collision of the transfer vehicles (18) when they move (step S11).

    Abstract translation: 确定并输入每个传送车辆(18)的移动范围(步骤S1)。 假设传送车辆(18)中的一个的故障,确定并输入剩余的转移车辆(18)的移动范围(步骤S2)。 判定各搬送车辆(18)的状态(步骤S3)。 如果所有的运送车辆18都正常,则应用步骤S1中确定的移动范围(步骤S4),并且如果任何一个运送车辆(18)发生故障,则应用在步骤S2中确定的移动范围。 确定搬送车辆(18)的搬出原点和搬入目的地(步骤S6),并搜索传送路线(步骤S7)。 之后,列出搜索到的路线候选(步骤S8),将传送路径修正为合理路径(步骤S9),并且针对每个候选路线计算传送时间(步骤S10)。 选择最短传送时间的传送路径,并且分配装置(22)被保留以便防止移动车辆(18)移动时的碰撞(步骤S11)。
