The profile may be loaded, manually entered, or generated by Curve. Since as much history as possible is used and is averaged over seven days, it's assumed that these profiles are de-causalized. The ratio of the magnitude estimate over the frequency estimate is the forecast level reported for the original series. These baselines are then spread back to the item/store level and then loaded in the RDF Causal Engine. The fit at time t, fit(t), is defined in terms of bo, the intercept of the regression, b1, the effect corresponding to promotional variable i, and pi(t), is the value of promo variable I, in time t as: The forecast is obtained by re-causalizing the baseline. You have the option of accepting the system-generated source-level selection or manually selecting a different source-level to be used. The complexity penalty is necessary to avoid over fitting. 3) User Guide RPAS Fusion Client(Rev. By using standard statistical distributional assumptions, RDF develops measures of uncertainty associated with forecast point estimates from these models. When inventory levels are optimized, lost sales due to product stock-outs are greatly reduced, as are the costs incurred by overstocking. Update the week-to-day profile of w36 so that the weight of Thursday is doubled (the multiplicative factor is 2): Finally, spread the forecast of w36 using the normalized profile. To do this, the promotional lifts are filtered from the historical sales and applied on top of the item's rate of sale. Users need to be aware that the forecasting models cannot tell the difference between causal effects and correlated effects. A combination of several seasonal methods. In order to make this feasible in a retail environment, Oracle Retail has developed a number of different meta-methods that can automatically select the best method among a number of competing models. The best aggregation status keeps track of which sub-problems have been performed and which sub-problems remain. This improves forecasts created using Holt over longer forecast horizons. Your sales plan can incorporate expert knowledge in two ways — shape and scale. Oracle Retail recently released our next generation Oracle Retail Demand Forecasting (RDF) Cloud Service. Improve Forecast Accuracy with Oracle Retail Demand Forecasting. and the Trend at the end of the series (time t) is: and the Seasonal Index for the time series (applied to the forecast horizon) is: Oracle Winters is a Winters-based decomposition approach to update the level, trend, and seasonal indexes. If yes, generate a forecast and statistics using the SimpleES method and move on to Step 4. Note that since each member of the model candidate list is actually a family of models, an optimization routine to select optimal smoothing parameters is required to minimize s for each model form (that is, to select the best model). Using this method, the resulting forecast for the original series is calculated. To forecast short-lifecycle promotional items, Causal deprices, depromotes, and smoothes the forecasting data source to generate the short lifecycle forecast causal baseline. A common benchmark in seasonal forecasting methods is sales last year. A problem arises due to potential lack of significant data (that is, when a promotional variable is not represented in the history, but it is present in the forecast region). Check the spelling of your keyword search. One or more of these subtasks is performed during each period that the computer is idle. Given that both sales plans and time series forecasts are available, an obvious question exists: When should the transition from sales plan to time series forecasting occur? The absence of a check mark in this measure causes the system to default to the Default Source level or the Source Level Override value if this has been set by you. If that PAE is better than the current best PAE (corresponding to the current best source generation level), the source generation level that generated that better PAE becomes the new best level. NOTE: Forecast150 is released in v15, and the Forecast special expression is decommissioned as of v15.0.1. Return the corresponding forecast and statistics for the system-selected forecast method and move on to the next time series. Thus, the output from the algorithm is a selection of promotional variables and the effects of those variables on the series. Causal Forecasting Method can calculate not only each individual promotion effect, but also the overlapping promotions effects. Statistical forecasting processes are relatively easy to implement, and the better the historical data, the better the resulting forecasts. READ OUR RETAIL FORECASTING BLOG REQUEST A DEMO Engage with … Retail Demand Forecasting Cloud Service Forecast Analyst {username} : {useremail} Please provide us with feedback on your Oracle Learning Subscription experience! Within AutoES, the model that minimizes the Bayesian Information Criterion (BIC) is selected as the final model. Oracle Retail Demand Forecasting (RDF) provides retail marketers with the ability to find meaningful patterns within consumer data, plan an accurate demand forecast, and … Businesses benefit greatly from the use of systematic statistical forecasting techniques that aim to accurately predict product demand, enabling these businesses to maintain sufficient product inventory levels. A final-level forecast is generated for each product/location combination using each potential source generation level. This method performs best when dealing with highly seasonal sales data with a relatively short sales history. What this means is that users should be wary of promotional effects attributed to an event that occurs at the same time every year. Oracle Retail Demand Forecasting Cloud Service (RDF CS) provides accurate forecasts that enable retailers to coordinate demand-driven outcomes that deliver connected customer interactions. Note that this profile is already computed for spreading the weekly forecasts to the day level. Content will be entered on the day of the Critical Patch Update release. When a baseline is used, the AutoES binary code executes in the following manner: The binary reads the history of the time series. Oracle Retail Demand Forecasting enables you to manage a single forecast to drive profitable planning and operations reflecting customer preferences. The value for the source forecast level can be manipulated in the Final Level view of the Forecast Maintenance workbook. If yes, generate a forecast and statistics using the Holt method and move on to Step 5. The scheduling of the Automatic Forecast Level Selection process (AutoSource) must be integrated with the schedules of other machine processes. Streamlines forecasting processes and provides actionable insight by highlighting potential problem situations that require intervention or opportunities that can be pursued proactively. The causal forecasting process has been simplified by first estimating the effects of promotions. Daily profiles are calculated using the Curve module. Forecasts for short horizons can be estimated with Simple Exponential Smoothing when less than a year of historic demand data is available and acts-like associations are not assigned in RDF. As forecasting consultants and software providers, Oracle Retail assists clients in obtaining good forecasts for future demands for their products based upon historical sales data and available causal information. There are a few solutions that make use of the effects from other similar time series. Sunday is reserved for generating forecasts. 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. Oracle Retail Demand Forecasting Cloud Service Empower Demand-Driven Retailing Maximize forecast accuracy for the entire product lifecycle with next-generation retail science paired with exception-driven processes and delivered on our platform for modern retailing. Oracle Retail Demand Forecasting (RDF) is a statistical and promotional forecasting solution. Can be generated with little historical data. Identifying the best aggregation levels for sets of products and locations can be divided into a number of sub-problems: Determining the best source-level forecast. In actual practice these algorithms have been and can be used to forecast a myriad of different data streams at any product/location level (shipment data at item/warehouse, financial data at dept./chain, and so on). Finally, the promotion effects are applied on top of the short-lifecycle causal baseline to generate the final forecast. The resulting feed is aggregated and then spread down using rate of sales as a profile to create a lifecycle curve. If yes, generate a forecast and statistics using the Seasonal Regression method and move on to Step 6. Our intuition tells us that instead of a hard-edge boundary existing, there is actually a steady continuum where the benefits from the sales plan decrease as we gather more historic sales data. If the effects are calculated at higher level than item/store, the effects are replicated down to item/store since the effects are multiplicative. An alternate solution is whenever a causal effect cannot be computed because of lack of significant data. This method lets the Multiplicative Seasonal and Additive Seasonal models compete and picks the one with the better fit. 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. Also, time series are often too noisy at that level. Oracle Retail Demand Forecasting is a highly automated tool that during periods of significant market disruption will react and adjust quickly as it is intended to do. One solution would be to do source-level causal forecasting and then spread down to the final-level. 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). Promotional Effects need to be able to be analyzed at higher levels in the retail product and location hierarchies. IT creates optimized inventory targets by item by location to meet demand and satisfy business and financial objectives. The SimpleES model is applied to the time series unless a large number of transitions from non-zero sales to zero data points are present. This section describes those techniques within RDF that generate forecasts directly from only a single time series. In order to determine the best level, a final forecast is generated for each product/location using each candidate source generation level. When calculating the causal forecast, the calculated causal effects are written back to the database. This chapter discusses the forecasting methods used in Oracle Retail Demand Forecasting in detail. The confidence interval is set to 1/3 of the DD value. 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. Providing multiple forecasting methods is only valuable if the appropriate model can be selected in an accurate and efficient manner. Expert-led Instructional Videos Hands-on Labs Role-based Learning Paths 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. Does that mean that at 12 weeks the time series results are irrelevant and that at 14 weeks the sales plan has no value? Built-in artificial intelligence and intuitive dashboards help retailers prevent overstocking and boost customer satisfaction. All of these methods attempt to best capture the statistical probability distribution previously discussed, and they do this by fitting quantitative models to statistical patterns from historical data. 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. Copy Forecasting Method copies the measure that was specified as Forecast Data Source in the Forecast Administration Workbook into the Forecast measure. In some instances, especially in retail, pure time series techniques are inadequate for forecasting demand. Because of this difference, Bayesian Forecasting is not included in AutoES. Retail Demand Forecasting For On Premise Config Consultant {username} : {useremail} Please provide us with feedback on your Oracle Learning Subscription experience! From sufficient data, RDF extracts seasonal indexes that are assumed to have multiplicative effects on the de-seasonalized series. 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. The method involves splitting the original time series into two new series: The magnitude series contains all the non-zero data points, while the frequency series consists of the time intervals between consecutive non-zero data points. Croston's method is used when the input series contains a large number of zero data points (that is, intermittent demand data). Recently, Oracle Retail evaluated the next-generation, cloud-native, retail demand forecasting solution against Best Buy’s current on-premises version where end-users were manually adjusting 50 percent of forecasts and found a 70% improvement of promotional forecasts. The Retail Demand Forecasting Cloud Service provides accurate forecasts that enable retailers to coordinate demand-driven outcomes that deliver connected customer interactions. Oracle Inventory Optimization Enables Retailers to Navigate Uncharted Demand ... Service can sit between a retailer's forecasting and supply chain systems to help highlight ... Oracle Retail. Then the effects are applied on top of a baseline that is created externally from the causal forecasting process. You can enable the use of this level by placing a check mark in the Pick Optimal Level measure for that product/location. The selected model is recorded in the database. Sometimes it is difficult to capture seasonality, trend, or causal effects on the final-level (item/store) due to scarcity of the data. Does the time series contain more than 52 weeks of input data? 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. The models in the candidate list include: These models include level information, level and trend information, and level, trend and seasonality information, respectively. Refer to Table 13-3, "Promo Effect Types" for information on the Override Higher Level type. The Automatic Forecast Level Selection feature of the system automates the selection of best aggregation level (forecast source-level) for each product/location combination. That is, more recent data is weighted more heavily than the past. Oracle Learning Subscriptions | Learn Oracle ... Oracle Learning Subscriptions Feedback Retail Demand Forecasting Cloud Service Introduction {username} : {useremail} Please provide us with feedback on your Oracle Learning Subscription experience! The most common statistical methodologies used are univariate. The spreading utilizes causal daily profiles, thus obtaining a causal forecast at the day granularity. In this case, base-level sales data is aggregated from the item/store level up to the style/store level. As point-of-sale data becomes available, the forecast is adjusted and the scale becomes a weighted average between the initial plan's scale and the scale reflected by known sales history. Put simply, the better the history of the variable being forecast, the stronger these statistical patterns are. In most retail situations, clients are interested in obtaining good product forecasts automatically with little or no human intervention. Scale, or magnitude, of a sales plan is the total quantity expected to be sold over the plan's duration. Oracle Retail Science Platform Cloud Service, Oracle Retail Offer Optimization Cloud Service, Oracle Retail Assortment and Item Planning Cloud Service, Oracle Retail Advanced Inventory Planning, Planning and Optimization Retail Learning Subscription. A forecasting algorithm was developed that merges a customer's sales plans with any available historical sales in a Bayesian fashion (that is, it uses new information to update or revise an existing set of probabilities. If this is the case, the method rejects itself out of hand and allows one of the other competing methods to provide the forecast. The Profile-based forecasting method can be successfully used to forecast new items. 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. Let us help you accelerate your next practice retail demand forecasting. Overview Dashboard: Contextualize forecasting impacts to key performance indicators. The following procedure outlines the processing routine steps that the system runs through to evaluate each time series set to forecast using the AutoES method. All rights reserved. If yes, generate the forecast and statistics using the Additive Winters method and move on to Step 9. The technical methods used are driven by the goal to provide the most accurate forecasts possible in an automatic and efficient manner. A style/store forecast is generated, and the forecast data is spread back down to the item/store level. A description of the competing models used within AutoES is described in "Exponential Smoothing (ES) Forecasting Methods". The current RDF Seasonal Regression forecasting model is designed to address these needs. Aggregate the preprocessed continuous day level promotional variables to the week level. Included is a discussion of the importance of confidence intervals and confidence limits, the time series methods used to generate forecasts, and how the best forecasting method is selected from a list of candidate models. This means that they are based solely on the history of one variable, such as sales. A promotion variable can represent an individual promotion or a combination of overlapping promotions. Calculate the forecast for w36 using the standard causal forecasting system with continuous indicators. In this case, the Croston's model is applied. To accomplish the first task, a stepwise regression sub-routine is used. Oracle Retail Demand Forecasting is highly flexible, and can be configured to take into account your unique demand drivers, like pricing or promotions. In the system, one of the key elements to producing accurate forecasts is using the system's ability to aggregate and spread sales data and forecasts across the product and location hierarchies. Companies with a truly demand-driven supply chain can grow sales by 4%, cut operations cost by 10%, and reduce inventory by 30%. (Doc ID 1265403.1) Last updated on DECEMBER 03, 2019. Oracle Retail’s Demand Forecasting Cloud Service (RDF CS) empowers retailers to centralize demand forecasts — from operations and vendor collaboration to … The technology features built-in AI and dashboards to help retailers prevent overstocking and boost customer satisfaction, according to a … Any retail scenario or marketing activity can be modeled in the solution, allowing you to make better planning and merchandising decisions based on better predictions. Forecast Scorecard Dashboard: Evaluate forecast accuracy and identify opportunities. Goal Figure 3-2 Forecast Level Selection Process.

The binary creates an internal promotional variable to allow the modeling of trend. Helps FEMSA/OXXO upgrade RDF from version 10.0 to version 13.1, Oracle Retail Demand Forecasting Data sheet Oracle This routine takes a time series and a collection of promotional variables and determines which variables are most relevant and what effect those relevant variables have on the series. The BIC criterion attempts to balance model complexity with goodness-of-fit over the historical data period (between history start date and forecast start date). If no, move on to Step 9. Produit Oracle Retail Demand Forecasting. Forecasting using only sales last year involves simple calculations and often outperforms other more sophisticated seasonal forecasting models. The system cannot distinguish between the promotional effect and the normal seasonality of the product. A Simple Exponential Smoothing model is then applied to each of these newly created series to forecast a magnitude level as well as a frequency level. Bayesian analysis considers a priori information as a starting point in development of a prediction. For each product/location combination, the best source forecast level identified by RDF appears in the Optimal source-level measure on this view. To solve this problem, the task of selecting best aggregation levels for product/location combinations is decomposed and processed piecemeal during times when the computer would normally be idle. The selection of the best level is based on a train-test approach. Simple moving average forecasts are frequently used in the system because they: Make few assumptions about the historical time series. The daily casual forecast process executes in the following manner: Preprocess the day-level promotional variables by multiplication with daily profiles. Oracle Retail Inventory Optimization Cloud Service comes with pre-built machine learning models that more accurately predict overall inventory levels; recommend inventory re-distribution; balance supply and demand to free up money tied up in excess inventory; and more. In source-level forecasting, data is aggregated first to a higher level across the product or location hierarchy (or both). Retailers can now improve inventory management through a single view of demand throughout their entire product lifecycle with the next generation Oracle Retail Demand Forecasting (RDF) Cloud Service. 27th February 2018 . Link to Product Website: https://www.oracle.com. Bayesian forecasting is primarily designed for product/location positions for which a plan exists. Best aggregation level procedures are run during idle computer periods. Decomposition allows level and trend to be optimized independently while maintaining a seasonal curve. However, they were not designed to work with sales histories of shorter than two years. 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. Get comprehensive training on the Oracle Retail Suite with over 250 hours of content and tutorials for application consultants, administrators, forecast analysts, and more. LoadPlan Forecasting Method copies the measure that was specified as Data Plan in the Forecast Administration Workbook into the Forecast measure. When optimizing the Seasonal Regression Model, the sales last year forecast is inherently considered, and it will automatically be used if it is the model that best fits the data. Promotional variables, internal promotional variables, promotional variable types, and the series itself are passed to the stepwise regression routine, with the historic data serving as the dependent variables. This method does not generate confidence and cumulative intervals when it is the final level method and no source level is specified. The technology features built-in AI and dashboards to help retailers prevent overstocking and boost customer satisfaction, according to a press release. The alpha is capped by 0.5 by default or the Max Alpha (Profile) value entered by the user. 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. In response to the global health crisis, Oracle has announced the launch of the new Oracle Retail Inventory Optimization Cloud Service. RDF uses a variety of predictive techniques to generate forecasts of demand. 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. The effects can be either: Calculated. Increased forecast accuracy depends on the strength of these patterns in relation to background irregularities. While this is of key concern for various optimization solutions of the forecast, the technical details are beyond the scope of this document. 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. In this way, when the best aggregation procedure is run, the procedure knows what the next sub-problem is. Does the time series contain any data point with sales equal qualify to forecast using Additive Winters method? For every item/store combination, calculate a normal week-to-day profile based on historic data.
