Abstract: Methods, systems, and platforms are described for digital placement and allocation planning. An unconstrained distribution of items in a retail supply chain may be determined from digital demand forecasts by aggregating the digital demand forecasts based on location identifiers. An item allocation ratio between shipping locations may be determined using a model based on items being ordered together and the speed of items being ordered. An unconstrained DPA plan may be generated, with the distribution and the ratio, for placing and allocating a projected total quantity. Constraints relating to the supply chain may be identified. In response to the constraints, a constrained distribution may be generated from an unconstrained distribution. A constrained plan may be generated in response to the constrained distribution. The unconstrained or constrained DPA plan may be sent to a plan executor for initiating movements of items according to the plan within the supply chain.

Abstract: Systems and methods for determining the availability of a shipping option on a per-item basis are described. A retail user interface is provided from an online retailer, the retail user interface includes a plurality of selectable items available for delivery to a customer. Shipping options are offered to the customer on a per-item basis dependent on the actual transit time from a retail location to a destination location.
