<p>PURPOSE:To prevent an after-process from being disordered, by taking preference of a delivery demand latency when both warehousing and delivery demand latencies are generated, while constituting it so as to be preferentially handled in succession of fixed frequency for the duration the delivery demand latency continues. CONSTITUTION:A warehousing control computer 14 receiving a warehousing demand signal performs continuously a warehousing demand interruption to a central computer 13 at a fixed time interval till this interruption is accepted. Likewise, a delivery control computer 15 performs a delivery demand interruption. The central computer 13 stores each of warehousing and delivery demand latencies in memory on the basis of information out of a stacker crane control computer. And, for the duration the stored delivery continuous handling frequency is below the specified numerical value, the delivery demand is preferentially handled and if it reaches the specified frequency and the warehousing demand latency is stored in memory, the warehousing demand is put into action. Like this, with the delivery operation given priority, disorder in a stacking process due to the delivery latency can be prevented.</p> |
