PURPOSE:To improve the operation rate by using data for showing a running request frequency distribution to each time zone determined experientially, and determining the number of times for running by single changing of an unmanned carrying car so as to become larger than the reference number of times of running, in the case the unprocessed quantity of a running request is large, and also, a decrease of the number of running requests is predicted. CONSTITUTION:Data for showing a running request frequency distribution to each time zone determined experientially is stored in a centralized control part 7, and the unprocessed quantity of a running request and the data for showing the running request frequency distribution are compared in the centralized control part 7. In the case the unprocessed quantity is large, and also, a decrease of the number of running requests is predicted, the number of times for running by single charging of an unmanned carrying car 1 is determined so as to become larger than the reference number of times of running, and the unmanned carrying car 1 is run along a main route 2 without executing new charging until a decrease time of the number of running requests. Accordingly, it can be run without generating trouble caused by charging deficiency. In such a way, the efficiency of the unmanned carrying device can be improved. |
