Function documentationParameter Optimization

 

You use this function to automatically optimize the parameters for the forecasting techniques regression and or smoothing. The forecast calculation uses the optimized parameters. Parameter optimization can take place as follows:

  • For the automatic selection between regression and smoothing

  • For all parameters of the regression forecasting technique

  • For the seasonal consideration for forecast the smoothing forecasting technique

You define optimization you want to use in Customizing.

Recommendation Recommendation

End of the recommendation.

This function takes a lot of time. Therefore, you should only schedule parameter optimization in a critical time window (creation of order proposals) if sufficient time is available.

Integration

You can activate and deactivate parameter optimization in the process control profile for FRP. If the frequency of parameter optimization is dependent on the forecast calculation days, you can configure a corresponding frequency type that is either location-specific or location-product specific. For more information, see Forecast-Relevant Profiles.

Prerequisites

  • The FRP Dispatcher must be activated in order to enable use of the automatic parameter optimization within the FRP run.

  • You can define how often you want the system to execute parameter optimization for each frequency type (daily, weekly, or dependent on forecast calculation) in the frequency profile for parameter optimization. For more information, see the Implementation Guide (IMG) for Forecasting and Replenishment under Start of the navigation path Forecasting and Replenishment Processor Next navigation step Maintain Process Control Profiles End of the navigation path.

Features

You can perform parameter optimization in the following ways:

  • With the FRP Dispatcher

    You can use the FRP Dispatcher to perform parameter optimization within the critical and non-critical time period. To do so, you must add the SAFRUN_CALIB task to the Dispatcher profile you use. You must add this task in the MD_AND_TECH_SYNCH sequence (non-critical time period) or in the AUTO_REPL_AND_OPRM sequence (critical time period). Alternatively, you can create a separate sequence for the above task and add it to the appropriate place in the Dispatcher profile.

  • With report /FRE/UI_FRP_SAFRUN_CALIBRATION

    If you want to perform parameter optimization outside the Dispatcher-controlled FRP run (neither in the critical nor in the non-critical time period), schedule this report as a background job whenever appropriate. For more information, see Background Processing of the FRP Run.
