20090012979 | METHODS AND SYSTEMS FOR PARTITIONING OF DATASETS FOR RETAIL SALES AND DEMAND CHAIN MANAGEMENT ANALYSIS - A partitioning system that provides a fast, simple and flexible method for partitioning a dataset. The process, executed within a computer system, retrieves product and sales data from a data store. Data items are selected and sorted by a data attribute of interest to a user and a distribution curve is determined for the selected data and data attribute. The total length of the distribution curve is calculated, and then the curve is divided into k equal pieces, where k is the number of the partitions. The selected data is thereafter partitioned into k groups corresponding to the curve divisions. | 01-08-2009 |

20090089143 | METHODS AND SYSTEMS FOR FORECASTING PRODUCT DEMAND DURING PROMOTIONAL EVENTS USING STATISTICAL CONFIDENCE FILTERS - 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. | 04-02-2009 |

20090172017 | Techniques for Multi-Variable Analysis at an Aggregate Level - Techniques for multi-variable analysis at an aggregate level are provided. Two or more datasets having different statistical data distributions and which are not capable of being aggregated are acquired. The values for variables in the two or more datasets are normalized to produce a single integrated dataset of normalized values.

Furthermore, the reduction in the number of variables improves the stability and predictive power of the regression models. | 12-31-2009 |

20100100421 | METHODOLOGY FOR SELECTING CAUSAL VARIABLES FOR USE IN A PRODUCT DEMAND FORECASTING SYSTEM - A method to select causal factors to be used within a causal product demand forecasting framework. The methodology determines the set of factors that have statistically significant effects on historical product demand, and hence are believed to be of greatest relevance in determining product demand changes in the future. The effects of all factors are determined simultaneously and the net effect of each variable is calculated. When several factors are operative at the same time, the net influence of each factor is calculated. Lesser and redundant factors in the causal forecasting model can be eliminated to improve the stability, scalability and efficiency of the model. The method is employed to optimize causal models to achieve maximum forecast accuracy. | 04-22-2010 |

20100138273 | REPEATABILITY INDEX TO ENHANCE SEASONAL PRODUCT FORECASTING - A repeatability score is described for determining the quality and reliability of product sales data for generating seasonal demand forecasts. The repeatability scores are calculated from seasonal sales data stored in a data warehouse. Products are sorted based on their reliability scores such that those products that are highly seasonal and have a reliable year-to-year demand pattern are used to form initial or unique demand models. Products that are determined to be less reliable based on their repeatability score are added to the unique demand models through an iterative matching process or left out of the unique demand models. | 06-03-2010 |

20100138274 | METHOD FOR DETERMINING DAILY WEIGHTING FACTORS FOR USE IN FORECASTING DAILY PRODUCT SALES - A product demand forecasting methodology is presented that applies daily weight values to a weekly forecast to determine daily forecasts for a product or service. The method determines daily weight values for use in forecasting current product sales by blending daily weight values calculated from historical demand data for both recent weeks and year-prior weeks. Recent weeks are used to account for recent correlations and alternation effects, and year-prior weeks are used to account for seasonality effects. The method automatically calculates a measure of significance for the daily weights calculated from the recent weeks and year-prior weeks. The significance of each week is applied as a weighting factor during the blending of recent weeks and year-prior daily weight values. | 06-03-2010 |

20100138275 | AUTOMATIC EVENT SHIFTING OF DEMAND PATTERNS USING MULTI-VARIABLE REGRESSION - A product demand forecasting technique is presented which employs multivariable regression analysis to identify demand associated with annual events and shift demand associated with those events when the events occur in different weeks of different years. Historical weekly product demand data is acquired for one or more years. An event influencing demand for products which occurs at in different weeks in a prior year than in the forecast year is identified. Mulitvariable regression techniques are used to analyze the historical weekly product demand data to determine demand components associated with the event. These demand components can then be removed from the historical weekly demand data and re-applied to weeks in the prior year corresponding to the week the event occurs in the forecast year to create a shifted historical weekly demand for said product. | 06-03-2010 |

20100153179 | AUTOMATIC CALCULATION OF FORECAST RESPONSE FACTOR - A forecast response factor (RF) determines how quickly product demand forecasts should react to recent changes in demand. When a product sales pattern changes (e.g., a sudden increase in product demand), RF is adjusted accordingly to adjust the forecast responsiveness. The present subject matter provides automatic calculation of the RF, based at least in part on the nature of the product sales (autocorrelation) and the status of recent forecasts (bias). | 06-17-2010 |

20100169165 | METHOD FOR UPDATING REGRESSION COEFFICIENTS IN A CAUSAL PRODUCT DEMAND FORECASTING SYSTEM - 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. A product demand forecast is generated by blending forecast or expected values of the non-redundant causal factors together with corresponding regression coefficients determined through the analysis of historical product demand and factor information. The improved method provides for the saving and updating of previously calculated intermediate regression analysis results and regression coefficients, significantly reducing data transfer time and computational efforts required for additional regression analysis and coefficient determination. | 07-01-2010 |

20100169166 | DATA QUALITY TESTS FOR USE IN A CAUSAL PRODUCT DEMAND FORECASTING SYSTEM - 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 improved method identifies linear dependent causal factors and removes redundant causal factors from the regression analysis. A product demand forecast is generated by blending forecast or expected values of the non-redundant causal factors together with corresponding regression coefficients determined through the analysis of historical product demand and factor information. | 07-01-2010 |

20100235225 | AUTOMATIC DETECTION OF SYSTEMATIC SALES PATTERNS USING AUTOCORRELATION TECHNIQUE - A method, based on autocorrelation techniques, for measuring the relative significance of the systematic versus random components of product sales data. The results of this determination can be used to improve product demand forecast and product seasonal profile determinations. When a product's sales variation is primarily due to systematic patterns, the accuracy of demand predictions and forecasts can be improved by understanding and modeling the underlying pattern. On the other hand, when variations in sales are merely random, these variations can be discounted when determining demand forecasts or product seasonal profiles. | 09-16-2010 |

20110004510 | CAUSAL PRODUCT DEMAND FORECASTING SYSTEM AND METHOD USING WEATHER DATA AS CAUSAL FACTORS IN RETAIL DEMAND FORECASTING - A method system for forecasting product demand using a causal methodology, based on multiple regression techniques. The methodology utilizes weather related data as a set of causal factors for retail demand forecasting. These weather related factors may include temperature, precipitation, snow, accumulated snow, or extreme weather conditions. | 01-06-2011 |

20110047004 | MODELING CAUSAL FACTORS WITH SEASONAL PATTTERNS IN A CAUSAL PRODUCT DEMAND FORECASTING SYSTEM - A method and system for forecasting product demand using a causal methodology, based on multiple regression techniques. In order to better predict product demand changes associated with causal variables having seasonal patterns, such as temperature, the method and system include a technique for removing the seasonal variation of causal variables, i.e., to de-seasonalize the causal factors. The de-seasonalized causal variables are utilized within the causal methodology to generate product demand forecasts. | 02-24-2011 |

20110054982 | METHODS AND SYSTEMS FOR RANDOMIZING STARTING RETAIL STORE INVENTORY WHEN DETERMINING DISTRIBUTION CENTER AND WAREHOUSE DEMAND FORECASTS - A method and system for determining distribution center or warehouse product order quantities of a slow selling product. The method includes the step of determining for each one of a plurality of stores supplied by the distribution center, a store order forecast for the slow selling product. The method generates a random beginning on-hand inventory value for stores with inventories below a minimum inventory threshold value. Store order forecasts are thereafter determined by subtracting the random beginning on-hand inventory value from store sales forecasts when the beginning on-hand inventory value is less than the minimum inventory threshold value, and subtracting the actual beginning on-hand inventory value from the store sales forecasts when the beginning on-hand inventory value is not less than the minimum inventory threshold value. The individual store order forecasts are accumulated to generate a distribution center demand forecast; which is compared with current and projected inventory levels for the product at the distribution center to determine distribution center order quantities necessary for maintaining a product inventory level sufficient to meet the distribution center demand forecast for the product. | 03-03-2011 |

20110054984 | STOCHASTIC METHODS AND SYSTEMS FOR DETERMINING DISTRIBUTION CENTER AND WAREHOUSE DEMAND FORECASTS FOR SLOW MOVING PRODUCTS - A method and system for determining distribution center or warehouse product order quantities of a slow selling product. The method includes the step of determining for each one of a plurality of stores supplied by the distribution center, a store sales forecast for the slow selling product. The method converts the store sales forecast to a stochastic forecast when the average rate of sale of the product is less than a minimum average rate of sale threshold value. Store order forecasts are thereafter determined by subtracting a store inventory value from the stochastic forecast when average rate of sale is less than the average rate of sale threshold value, and subtracting the store inventory value from the sales forecast when the average rate of sale is not less than said average rate of sale threshold value. The individual store order forecasts are accumulated to generate a distribution center demand forecast; which is compared with current and projected inventory levels for the product at the distribution center to determine distribution center order quantities necessary for maintaining a product inventory level sufficient to meet the distribution center demand forecast for the product. | 03-03-2011 |

20110153385 | DETERMINATION OF DEMAND UPLIFT VALUES FOR CAUSAL FACTORS WITH SEASONAL PATTERNS IN A CAUSAL PRODUCT DEMAND FORECASTING SYSTEM - An improved method and system for forecasting product demand using a causal methodology, based on multiple regression techniques. The causal method uses both historical and future values of causal factors for causal forecasting. Historical values are used to build a causal model, i.e., to determine the influence of the causal factors upon the demand for a product, and future values are used to generate demand uplifts which applied to an initial demand forecast based upon historical product demand. The improved causal method provides different processes for the calculation of demand uplifts associated with seasonal variables, such as temperature, than typical, non-seasonal causal variables, such as product price. Demand uplifts for seasonal variables are determined from the difference between a forecast value for the seasonal variable and an average of corresponding historical, prior-year, values of the seasonal variable, and demand uplifts for non-seasonal variables are determined from the difference between a forecast value for the non-seasonal variable and an average of recent values of the non-seasonal variable. | 06-23-2011 |

20110153386 | SYSTEM AND METHOD FOR DE-SEASONALIZING PRODUCT DEMAND BASED ON MULTIPLE REGRESSION TECHNIQUES - An improved method and system for forecasting product demand using a causal methodology, based on multiple regression techniques. The improved causal method revises product group seasonal factors used by conventional forecasting applications to best fit the sales pattern of an individual product in the product group through the calculation of an exponential coefficient which measures the deviation of the historical sales pattern of an individual product from the product group seasonal factors. The value of exponential coefficient is calculated using a causal framework through multivariable regression analysis. | 06-23-2011 |
