<p>PROBLEM TO BE SOLVED: To prevent the non-uniform allocation of carrying instructions by averaging the empty vehicle passing ratio at each station, and uniformly distributing circulating empty vehicles waiting for the execution of the carrying instructions on a close loop carrying track. SOLUTION: Plural stations are arranged on a closed loop-shaped carrying track 1 on which plural carrying trucks 3A and 3B are traveling. In this case, the carrying trucks 3A and 3B are allowed to travel so that the empty vehicle passing ratio at each station 2 can be made almost uniform, and the circulating empty vehicles 3B waiting for the execution of carrying instructions are almost uniformly distributed on the carrying track 1.</p> |
