When this forecasting method is selected, the forecasts are seen as trending either up or down, as shown in Figure 3-5. The Logic team brings the hands-on supply chain experience your organization needs to successfully implement, deploy, and manage Oracle Retail’s leading Supply Chain Management & Optimization solutions. Frequently, clients already have some expectations of future demands in the form of sales plans. Demand Forecasting: Base Releases: 16.0: Release Notes: Installation Guide(Rev 2) User Guide RPAS Classic Client(Rev. The forecast is calculated using the DD value multiplied by the profile. Now assume that the same promotion is held in a future week (w36), but only on Thursday: Then the continuous weekly indicator for w36 should be set to 0.1, which is the weight of Thursday only. Sometimes it is difficult to capture seasonality, trend, or causal effects on the final-level (item/store) due to scarcity of the data. If this is the case, the method rejects itself out of hand and allows one of the other competing methods to provide the forecast. For any assistance regarding the above and other forecasting changes that you may be experiencing please set up a call for assistance or email Guiming Miao , Oracle Retail Director of Science, for more tips. 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)). They are exponential smoothing models because the weighting uses decays at an exponential rate. In such a case, the simpler model captures the basic features supported by the data without over fitting and therefore generally projects better forecasts. As illustrated in Figure 3-2, a final forecast is generated by: Aggregating up from the base level to the source-level, Spreading the source-level forecast down to the final-level. Calculate the forecast for w36 using the standard causal forecasting system with continuous indicators. In order to determine these values, we need to analyse our historical data (this has got nothing to do with the data in RDF now - it could be in excel). For example, assume base-level sales data is at the item/store level, the final forecast level is at the item/store level, and the candidate source generation level is at the style/store level. The technology features built-in AI and dashboards to help retailers prevent overstocking and boost customer satisfaction, according to a press release. Forecast Approval Workspace: Interact with forecast results through visual and fit-for-purpose user interface. 27th February 2018 . With Oracle Retail Demand Forecasting RETAIL MARKET REALITIES THE UPSIDE OF UPGRADING MODERN RETAIL IMPERATIVES FUTURE PROOF INVESTMENT With over 5,280 customers worldwide, Oracle is the platform for modern retail around the globe. This release features robust machine learning, artificial intelligence and decision science, enabling retailers to gain pervasive value across forecasting and planning processes. Oracle Retail’s Demand Forecasting Cloud Service (RDF CS) empowers retailers to centralize demand forecasts — from operations and vendor collaboration to … Copyright © 2018, Oracle and/or its affiliates. When the Multiplicative Seasonal forecasting method is selected, the forecasts tend to look squiggly, as shown in Figure 3-6. From sufficient data, RDF extracts seasonal indexes that are assumed to have multiplicative effects on the de-seasonalized series. There are a few solutions that make use of the effects from other similar time series. The system determines the multiplicative and additive weights that best fit the data on hand. This curve represents the pre-season baseline forecast. Cancel Submit Feedback. Statistical forecasting processes are relatively easy to implement, and the better the historical data, the better the resulting forecasts. If there have been significant shifts in the level of sales from one year to the next, the model learns that shift and appropriately weigh last year's data (keeping the same shape from last year, but adjusting its scale). Because of this difference, Bayesian Forecasting is not included in AutoES. In some instances, no promotional variables are found to be statistically significant. Solution allows retailers to maintain a single projection of forecasted demand across all commerce anywhere operations efficiently and accurately. Expert-led Instructional Videos Hands-on Labs Role-based Learning Paths 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. The seasonal models used in earlier releases of RDF (Additive and Multiplicative Winters) were designed to determine seasonality. Companies with a truly demand-driven supply chain can grow sales by 4%, cut operations cost by 10%, and reduce inventory by 30%. Regression uses a least-squares estimator to fit a model of predictor variables to another set of target variables. The following is an example of a typical schedule for the Automatic Forecast Level Selection process: Monday through Thursday, the selection process starts at midnight and runs for eight hours. The confidence interval is set to 1/3 of the DD value. There are various equivalent versions of the Bayesian Information Criterion, but RDF minimizes the following: where n is the number of periods in the available data history, k is the number of parameters to be estimated in the model (a measure of model complexity), and s is the root mean squared error computed with one-step-ahead forecast errors resulting from the fitted model (a measure of goodness-of-fit). This section describes those techniques within RDF that generate forecasts directly from only a single time series. Daily profiles are calculated using the Curve module. This section describes how the automatic forecast level selection (AutoSource) could help improve the accuracy of your forecasts. A wide variety of statistical forecasting techniques are available, ranging from very simple to very sophisticated. Get comprehensive training on the Oracle Retail Suite with over 250 hours of content and tutorials for application consultants, administrators, forecast analysts, and more. A sales last year forecast is based entirely on sales from the same time period of last year. A combination of several seasonal methods. Bayesian Forecasting assumes that the shape that sales takes is known, but the scale is uncertain. This method performs best when dealing with highly seasonal sales data with a relatively short sales history. Results included: - Improved flash sale revenue, unit sales and margin by over 300% - Improved demand forecasting accuracy for new products What this means is that users should be wary of promotional effects attributed to an event that occurs at the same time every year. An alternate solution is whenever a causal effect cannot be computed because of lack of significant data. For example, the overall sales level of the product, how quickly the product takes off, how the product's sales is affected by planned promotions. The most common statistical methodologies used are univariate. Overview Dashboard: Contextualize forecasting impacts to key performance indicators. Engage with Oracle Retail Planning and Optimization Learning Subscription and maximize your planning and optimization solution investment with an all-new, modern learning experience. That is, when aggregate forecasts can be calculated for long and less noisy aggregate time series, Simple Moving Average models provide an adequate (and computationally quick) forecast to determine the ratios needed for RDF spreading. The binary reads the type of each promotional variable into the system. If no, do not forecast and go to the next time series. Oracle's Supply Chain Optimization retail-specific offering is tailored to deliver benefits for or across all retail formats: Organization-wide demand forecast reflecting all key demand influencers Time-phased inventory replenishment throughout the supply chain Once we have enough history (number of data points exceed a global parameter), the forecast stops using the DD value, and it defaults to the normal Profile Based method. RDF uses a variety of predictive techniques to generate forecasts of demand. If multiple plans are to be set up for different time periods, the domain should be set up with different forecasting levels for each time period of interest. The amount of available historic information can affect the complexity of the model that can be fit. The Oracle Retail experience in promotional forecasting has led us to believe that there are a few requirements that are necessary to successfully forecast retail promotions: Baseline forecasts need to consider seasonality; otherwise normal seasonal demand is attributed to promotional effects. In the Oracle Retail approach to causal forecasting, the causal effects are obtained by fitting a stepwise linear regression model that determines which variables are most relevant and what effect those relevant variables have on the series. In this process, historical data is used to generate a forecast for a test period for which actual sales data already exists. Retail Demand Forecasting Cloud Service Forecast Analyst {username} : {useremail} Please provide us with feedback on your Oracle Learning Subscription experience! Instead of using only historic demand patterns to forecast future demand, additional causal or promotional factors are used to better explain past performance. For every item/store combination, calculate a normal week-to-day profile based on historic data. Forecast Scorecard Dashboard: Evaluate forecast accuracy and identify opportunities. In this case, the forecast equals the baseline. Any time period with non-zero Actuals for a given product/location position should have a corresponding plan component.

Produit Oracle Retail Demand Forecasting. Rather than use a sales history that may not have sufficient or accurate data, users can load a baseline into the RDF Causal Engine instead. When AutoES forecasting is chosen in RDF, a collection of candidate models is initially considered. Take your retail business to the next level with a proven suite of retail science applications, purpose-built and field-tested for specific retail use cases. Promotional Effects need to be able to be analyzed at higher levels in the retail product and location hierarchies. In some instances, especially in retail, pure time series techniques are inadequate for forecasting demand. Oracle Retail Demand Forecasting Oracle Retail Demand Forecasting enables you to manage a single forecast to drive profitable planning and operations reflecting customer preferences. The Level at the end of the series (time t) is: The Trend at the end of the series (time t) is: The Seasonal Index for the time series (applied to the forecast horizon) is: Oracle Winters, calculates initial seasonal indices from a baseline Holt forecast. If less than two years of data is available, a Seasonal Regression model is used. The causal forecasting at the daily level is calculated by spreading the weekly causal forecast down to day. The current RDF Seasonal Regression forecasting model is designed to address these needs. Oracle Retail Demand Forecasting (RDF) is a statistical and promotional forecasting solution. Seasonal Regression is an Oracle Retail specific extension of this procedure for use in seasonal models with between one and two years of history. Then the forecast is generated and proportionally spread down to the final-level. Retail Demand Forecasting Cloud Service Forecast Analyst {username} : {useremail} Please provide us with feedback on your Oracle Learning Subscription experience! Oracle Retail’s 2020 consumer study found that 53% of global consumers feel that new and exciting products and assortments with personalized offers are essential for continuing to shop with a retailer. If no, move on to Step 8. The data is de-seasonalized using the profile and then fed to Simple method. An averaged effect from another time-series in the same aggregation class is going to be used instead. Figure 3-3 is an example of a forecast in which data seems to be un-trended and un-seasonal; note the flat appearance of the forecast. ORACLE RETAIL DEMAND FORECASTING. Otherwise, the system assumes a plan exists and equals zero and acts accordingly. Initially the implementation of RDF was going to cover FMCG, hardlines, textiles and electronics and complete within one year. Causal Forecasting uses stepwise regression to determine which causal variables are significant. Confidence in the sales plan is controlled by the amount of sales data on hand and a Bayesian sensitivity constant (Bayesian Alpha), which you can set between zero and infinity. A common benchmark in seasonal forecasting methods is sales last year. Then the forecast data source is depriced, depromoted and smoothed. The Seasonal Regression Model is included in the AutoES family of forecasting models and is thus a candidate model that is selected if it best fits the data. Since as much history as possible is used and is averaged over seven days, it's assumed that these profiles are de-causalized. With Oracle Retail Demand Forecasting Cloud Service, you stay on the cutting edge of forecasting science and get the most for your team.

Try one of the popular searches shown below. Calculate the multiplicative promotional effects at the item/store level for every promo variable. The following topics present fundamentals of the RDF statistical forecasting processes. Baselines are often generated using data that is rolled up to a higher dimension than item/store, providing a greater depth of data and hence a less-noisy sales history. If no, move on to Step 9. If you want to force certain promotional variables into the model, this can be managed through forecasting maintenance parameters.

Oracle Retail Demand Forecasting Cloud Service (RDF CS) provides accurate forecasts that enable retailers to coordinate demand-driven outcomes that deliver connected customer interactions. While providing invaluable information regarding the best aggregate level for source forecasts, the Automatic Forecast Level Selection process may be very CPU intensive. Balance inventory throughout the supply chain to efficiently achieve desired service levels to customers by providing optimized replenishment recommendations. Your source for Oracle Retail customer content, event proceedings, and solution updates. By aggregating the promotional variables at the source-level, we would force the effects on the other time series in the same aggregation class that would otherwise not have the causal variables on at the same time. The time series methods that the system offers include: Exponential Smoothing (ES) Forecasting Methods - Automatic Exponential Smoothing (AutoES), Simple/Intermittent Exponential Smoothing, Multiplicative Winters Exponential Smoothing, Seasonal Exponential Smoothing (SeasonalES). Does the time series qualify to forecast using the Multiplicative Winters method? 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 source-level forecasting is used and causal method is used both at the source-level and at the final-level, the effects from the final-level is used. The Holt model provides forecast point estimates by combining an estimated trend (for the forecast horizon - h) and the smoothed level at the end of the series. Goal.
