Abstract: A method including generating, by separate instances of a multi-threaded worker system, respective lists of zip codes that fulfillment nodes in a fulfillment network can deliver to via ground shipping within a first shipping time period, based at least in part on preliminary eligibility information and an evaluation of current factors. The method also can include transforming, with an aggregator system, the respective lists of zip codes to generate a mapping from each zip code in the respective lists of zip codes to a respective list of the fulfillment nodes that can deliver via ground shipping to each zip code within the first shipping time period. The method additionally can include receiving a request comprising an input zip code and an input shipping time period.

Abstract: Described in detail herein are simulation systems for a production environment and related methods of use. In one exemplary system a routing application receives a request associated with one or more physical objects. Based on the request, the routing application retrieves one or more simulation profiles from a database and forwards the request and the simulation profiles to a first computing system. The first computing system hosts a simulation environment and simultaneously executes a simulation of the request for each simulation profile in the simulation environment. The first computing system generates resultant data in response to executing each simulation that may be used to alter a production application for a production environment.

Abstract: A method including generating a first list of fulfillment nodes of fulfillment nodes that are enabled to deliver within a first shipping time period. The method also can include sending each fulfillment node to a separate instance of a multi-threaded worker system. The method additionally can include generating a list of zip codes that the input fulfillment node can deliver to via ground shipping within the first shipping time period. The method additionally can include transforming the lists of zip codes to generate a mapping from each zip code in the lists of zip codes to a list of fulfillment nodes of the fulfillment nodes that can deliver via ground shipping to the each zip code within the first shipping speed. The method additionally can include receiving a request including an input zip code and an input shipping time period.

Abstract: Systems and methods including one or more processing modules and one or more non-transitory storage modules storing computing instructions configured to run on the one or more processing modules and perform acts of coordinating displaying a set of items of an online retailer on a user interface of a customer electronic device of a customer; receiving, from the customer electronic device, a first selection by the customer of a first item of the set of items to place the first item in an electronic shopping cart of the customer for a customer order; determining a first shipping cost to the online retailer for a first delivery of the first item to the customer by a first date from a first shipping location; determining a second shipping cost to the online retailer for the first delivery of the first item to the customer by a second date from the first shipping location, the second date occurring after the first date and the second shipping cost being less than the first shipping cost; determining a first order d
