Cart picking process is also man-to-goods based, but the concept here is one man collecting several orders at once. It could be executed by means of same pick by light equipment mounted on specific trolleys or it could be performed by any platform on a vehicle (even on a hand-pushed cart) a few labeled containers (e.g. carton boxes for sorting the goods by order) and a picking list (it’s better to be displayed on mobile terminal as a task list). The WMS governs task execution and directs the operator to the optimal route in the warehouse. It is very handy in term of collecting small goods or small packs.
