Oracle Retail Demand Forecasting enables you to manage a single forecast to drive profitable planning and operations reflecting customer preferences. No results found. Through training, you will learn about traditional forecasting through a variety of forecast methods and how to leverage this solution to help your business align operations across global networks. If no, do not forecast and go to the next time series. The daily casual forecast process executes in the following manner: Preprocess the day-level promotional variables by multiplication with daily profiles. For example, the shape for certain fashion items might show sales ramping up quickly for the first four weeks and then trailing off to nothing over the next eight weeks. One solution would be to do source-level causal forecasting and then spread down to the final-level. For stable products with years of historic sales data, our time series approaches (Simple, Holt, Winters, Regression based Causal, and so on) produce adequate results. The Simple forecast is re-seasonalized using the profiles. This means that they are based solely on the history of one variable, such as sales. The Profile-based forecasting method proceeds as follows: The historical data and the profile are loaded. A common benchmark in seasonal forecasting methods is sales last year. These baselines are then spread back to the item/store level and then loaded in the RDF Causal Engine. Improve Forecast Accuracy with Oracle Retail Demand Forecasting. The Retail Demand Forecasting Cloud Service provides accurate forecasts that enable retailers to coordinate demand-driven outcomes that deliver connected customer interactions. Engage with Oracle Retail Planning and Optimization Learning Subscription and maximize your planning and optimization solution investment with an all-new, modern learning experience. The time period of interest for the Bayesian algorithm starts with the first non-zero value of the plan or the history start date (whichever is more recent), and ends at the end of the forecast horizon. First, since it is logically impossible to receive a negative value for the slope (such a value suggesting an inverse seasonality), whenever a negative slope is detected, the regression is rerun with the intercept fixed to zero. Thus, the output from the algorithm is a selection of promotional variables and the effects of those variables on the series. To accomplish the first task, a stepwise regression sub-routine is used. In order to improve inventory accuracy and optimise sales forecasts, they decided to bring forecasting systems and processes in-house using Oracle RDF. The inability to include planners' intuition into a forecasting model. Let us help you accelerate your next practice retail demand forecasting. Simple Exponential Smoothing does not consider seasonality or trend features in the demand data (if they exist). The current RDF Seasonal Regression forecasting model is designed to address these needs. Oracle's Retail Demand Forecasting Cloud Service aims to help retailers boost inventory management by providing a single view of demand through the product lifestyle. An alternate solution is whenever a causal effect cannot be computed because of lack of significant data. Refer to Figure 3-1, "AutoES Flowchart". Since this model does not use a smoothing parameter to place added weight on more recent historic values, a Simple Moving Average model is not actually in the exponential smoothing family. If the effects are calculated at higher level than item/store, the effects are replicated down to item/store since the effects are multiplicative. Return the corresponding forecast and statistics for the system-selected forecast method and move on to the next time series. Does the time series contain enough relevant data to generate a forecast? These include reducing the number of parameters the Winter's model is penalized by discounting seasonal indices that have little impact on the forecast (multiplicative indices close to one (1), additive indices close to zero (0)).

The regression method provides a much better forecast of the series than was possible with the other exponential smoothing algorithms. Figure 3-4 shows a sales history of data where the demand for a given period is often zero. These forecast updates can be critical to a company's success and can be used to increase or cancel vendor orders.
