Abstract:
Forecasting serves as the basis of subsequent planning steps, Although
Rahimafrooz Battery Company uses commercial ERP system, it docs nol have a
good qualitative forecasting system. As such, development of a good forecasting
system was largeted in this research. FOrccasling & statistical analysis have been
done by collecting the past six years data of different types ofbalteries. Five types
of industrial batteries such as, IB-Local, 113-IPS,IB-Solar, IB-Export, IB-VRLA
arc considered for different types of analysis. Moving Average and Least Square
Method are applied for forecastIng different types of batteries. Different types of
trends are carefully examined by correlation lest and Hypothesis test is done for
statislical analy~is. Examining the past six years of data Seasonal Factor is
inlroduced. By using Seasonal Faclor and dividing each year into four different
quarters, accurate forecasting has been done. According to lhe different analysis, it
is seen that there is a sharp increasing trend of demand oftbe IB-IPS and !B-Solar
type of batteries. On the other hand, there is a decreasing trend of demand of lBLocal,
iB"Export, IB-VRLA type of batterie;.
