Abstract: Many facilities in supply chains have pallets and containers that can be stacked. Stacking containers during material handling can improve the efficiency of warehouse operations; however, this has largely been ignored by researchers. A time-based model is proposed to generate routes that material handling vehicles use for picking and storing containers that includes the ability to stack pallets during transport and to use multi-command operations. For warehouses that store and pick millions of containers each year, small improvements in each trip can have a dramatic cumulative effect on the annual cost savings.

Keywords: multi-command operations; warehouse operations; time-based warehouse models.
