Expert Answer



Linear trend y = a+bx

a = intercept

b = slope

x = time period

y = forecast for demand for period x

b = (sum xy - nbar{x}bar{y})/(sum x^{2}-nbar{x}^{2})


n = no of peiods

bar{x}=sum x/n = the mean of the x values

bar{y}=sum y/n = the mean of the y values

Slope b = (635-(7*4*21))/(140-(7*4*4)) = 47/28 = 1.68

Intercept a = 21-(1.68*4) = 14.28

Y = 14.28 + 1.68x

Forecast for september(x=8) =14.28+(1.68*8) = 27.72


Exponential smoothing Ft

F_{t}=F_{t-1}+alpha (A_{t-1}-F_{t-1})

Ft = new forecast

Ft-1 = previous period forecast

At-1 = Previous period actual demand

alpha = smoothing constant

Forecast for september = 20.27
