摘要:
An improved method for forecasting and modeling product demand for a slow moving product. The method includes the steps of maintaining a database of historical product demand information, calculating the average rate of sales (ARS) for a product from the historical demand information corresponding to the product, determining if the product is a slow moving product (SMP), and if the product is a SMP modifying the ARS using a mean reverting forecast method called GARCH (Generalized Autoregressive Conditional Heteroscedasticity) to accurately model the expected demand and variability of the slow moving product.

A method and system for forecasting distribution center (DC) or warehouse product suggested order quantities required to meet future product demands for a retailer. In determining DC/warehouse order quantities, a bias factor and Adaptive Forecast Error (AFE) are calculated from prior product demand and sales data and applied to DC/warehouse effective inventory calculations to account for forecast errors in DC/warehouse suggested order quantities. If the bias indicates a forecast that is too high, the method and system will attempt to compensate by increasing the suggested order quantity. If the bias indicates a forecast that is too low, the method and system will attempt to compensate by decreasing the suggested order quantity.
摘要:
Techniques for casual demand forecasting are provided. Information is extracted from a database and is preprocessed to produce adjusted input regression variables. The adjusted input regression variables are fed to a regression service to produce regression coefficients. The regression coefficients are then post processed to produce uplifts and adjustments to the uplifts for the regression coefficients.

An improved method for forecasting and modeling product demand for a product. The forecasting methodology employs a causal methodology, based on multiple regression techniques, to model the effects of various factors on product demand, and hence better forecast future patterns and trends, improving the efficiency and reliability of the inventory management systems. The demand forecasting technique seeks to establish a cause-effect relationship between product demand and factors influencing product demand in a market environment. Such factors may include current and recent product sales rates, seasonality of demand, product price changes, promotional activities, weather forecasts, competitive information are examples of the other primary factors which can be modeled. A product demand forecast is generated by blending the various influencing factors in accordance with corresponding regression coefficients determined through the analysis of historical product demand and factor information.

An improved method for forecasting and modeling product demand for a product during promotional periods. The forecasting methodology employs a multivariable regression model to model the causal relationship between product demand and the attributes of past promotional activities. The model is utilized to calculate the promotional uplift from the coefficients of the regression equation. The methodology utilizes a mathematical formulation that transforms regression coefficients, a combination of additive and multiplicative coefficients, into a single promotional uplift coefficient that can be used directly in promotional demand forecasting calculations.

An improved method for forecasting and modeling product demand for a product during promotional periods. The forecasting methodology employs information about prior promotional demand forecasts, prior product sales, and the data dispersion and the number of data samples in a product class hierarchy to dynamically determine the optimal level at which to compute promotional uplift coefficients. The methodology calculates confidence values for promotional uplift coefficients for products at each level in a merchandise product hierarchy, and uses the confidence values as a filter to determine the optimal level for promotional uplift aggregation.

摘要:
A method has been devised to produce a Confidence Prediction metric which gives the business user some indication as to the future reliability of the current week's forecast. The forecasting method analyzes historical demand data and prior product demand forecasts to calculate forecast errors for the prior product demand forecasts, and determine a confidence level for current and future product demand forecasts, the confidence level providing an indication of whether a given product forecast is unreliable or not. Reliable product demand forecasts can be automatically passed to a purchase order system, while unreliable forecasts may need to be reviewed and adjusted manually. A method for assessing, before-hand, whether a given product's forecast is reliable has been devised.

A method for determining daily weight values and store closure coefficients for use in forecasting daily sales patterns for retail products. The method uses historical daily demand data for a product to calculate a daily weight value for the product for each day of the week, each daily weight value representing the ratio of the historical daily demand for a corresponding day of the week to a total of the historical daily demands for the entire week. A daily demand forecast for each day of a forthcoming week is determined by applying the daily weight values to a predetermined weekly demand forecast for the forthcoming week. Historical demand data for weeks including holidays or store closures is used to calculate store closure coefficients, representing the ratio of the historical daily demand for days immediately preceding and following a store closure, to the historical demand for a corresponding day during a regular, non-holiday, week. The store closure coefficients are applied to the daily demand forecasts for days immediately preceding and following store closures or holidays to adjust the daily forecasts to accommodate changes in customer buying patterns resulting from the store closures.
