Picking station with return processing

Abstract

A method and system for fulfilling customer orders having a data base that is adapted to store a plurality of customer orders and identity of warehouse inventory items and return inventory items that make up each of the customer orders. Some of the orders are single item orders with only one inventory item assigned to that order. Some of the orders are multiple item orders with multiple inventory items assigned to that order. Returned items that are processed and determined to be acceptable to be re-distributed are re-introduced into the inventory data base and are available to be assigned to an order. Warehouse inventory and return inventory are maintained independent of each other to reduce redundant operations. The order fulfilment system retrieves items from either or both of the warehouse inventory and return inventory to fulfil customer orders. The order fulfilment system may utilizes human associates or robot associates.
