Demand modeling uses statistical methods and business intelligence inputs to generate accurate demand forecasts and effectively address demand variability. Demand modeling is becoming more important because forecasting and inventory management are being complicated by the increasing number of slow-moving items, the so-called “long-tail” of the product range, many of which have unpredictable demand patterns in which the typical “normal distribution” assumption used by traditional models is totally inadequate. In these scenarios, successfully managing forecasts and inventories requires advanced demand and inventory modeling technologies in order to reliably support high service levels.

Spot market profit optimization system
A profit optimization system takes account of supply-side and demand-side factors in optimizing profit for an organization. The profit optimization system uses an optimization model to optimize profit in a spot market. The model takes into account which parts the organization uses to assemble various products. Demand curves are used to characterize the quantity of each product that will be demanded as a function of price on the spot market. Supply model data is used to determine which mix of products can be sold in view of parts availability. Using the demand model and supply model data, the optimization model can recommend a set of prices to use for selling the organization's products. The model ensures that the organization has sufficient resources available to produce the products and enforces user-supplied business rules and other constraints.
