Abstract: A method includes selecting a plurality of operational components to which operational resources are allocated, selecting a plurality of control signals for the plurality of operational components, applying the plurality of control signals to the plurality of operational components to determine an operational effect of the plurality control signals on the operational components, applying a resource requirement for each of the plurality of operational components, determining, using a queue optimization model, a first control signal target value, based on the operational effect of each of the plurality of control signals on each of the plurality of operational components and the resource requirement for each of the plurality of control signals for each of the plurality of operational components, and assigning, based on the first control signal target value, an operational resource allocation to each of the plurality of operational components.

Abstract: A method is provided that comprises determining a first time period during which a first product is available in an inventory at a point of purchase according to a model that uses (a) sales data, (b) inventory data, or (c) both sales data and inventory data. The inventory data comprises data from an inventory management system, sampled during the first time period, as an input. The method further comprises determining a second time period during which the first product is unavailable in the inventory according to the model and comparing a first time period sales data to a second time period sales data to determine a product unavailability effect. The method also comprises using the product unavailability effect to change an assortment at the point of purchase.
