Crane control of an automatic storage & retrieval system

The nature of how an Automatic Storage & Retrieval System stacker crane moves through the aisle, between picking and storing operations, is analyzed through a simulation model. A continuous SLAM model simulates the performance of a single aisle Automatic Storage & Retrieval System stacker crane under various control conditions. Crane speed, acceleration rate, job arrival rate, and discrete or continuous interrupt sensing are the variables examined within the model. The performance level of the system is observed while altering the control.
