Hi Experts
We have requirement of forecast and replenishment by taking average of the sales/consumption value of a particular day(monday,tuesday) of the past 4 weeks.
We have tried using seasonal model....making 7 days as one season and then carried out forecasting.The forecast values were appearing appropriate, but as days went by forecast values showed drastic fluctutaions........I guess due to the seasonal index.
Currently we are working on SAP Retail
Please suggest a solution to forecast a value which would average out the corrsponding consumption of a particular day of 4 weeks.This is to consider the high sales on weekends and low on weekdays
For eg - If we are forecasting for a sunday, system should average out last 4 sundays consumption value.
We are facing issues in complpeting deadlines.Quick response would be appreciated.
It wiil be great if someone also explains the behaviour of the seasonal index(depending on the gamma factor) and how to control it.
Regards,
Arijit
