Optimizing order fulfillment processes

Abstract

A method of order fulfillment at a fulfillment center includes: identifying, from a list of unfulfilled orders at a fulfillment center (FC), a plurality of item retrieval routes associated with order-items in the FC, where each item retrieval route represents a route for the collection device configured to collect corresponding one or more order-items and is determined based on information associated with the collection device; and identifying, based on location information of the collection device and the information, a subset of item retrieval routes, among the plurality of item retrieval routes, to be assigned to the collection device for a fulfillment process such that an efficiency metric associated with the subset of item retrieval routes satisfies a threshold condition, the fulfillment process including (i) collecting order-items within the subset of item retrieval routes and (ii) delivering collected order-items to a corresponding destination of each item retrieval route.
