Answer:
Step-by-step explanation:
Forecast for period 1 is 5
Demand For Period 1 is 7
Demand for Period 2 is 9
Forecast can be given by
[tex]F_{t+1}=F_t+\alpha (D_t-F_t)[/tex]
where
[tex]F_{t+1}=Future Forecast[/tex]
[tex]F_t=Present\ Period\ Forecast[/tex]
[tex]D_t=Present\ Period\ Demand[/tex]
[tex]\alpha =smoothing\ constant[/tex]
[tex]F_{t+1}=5+0.2(7-5)[/tex]
[tex]F_{t+1}=5.4[/tex]
Forecast for Period 3
[tex]F_{t+2}=F_{t+1}+\alpha (D_{t+1}-F_{t+1})[/tex]
[tex]F_{t+2}=5.4+0.2\cdot (9-5.4)[/tex]
[tex]F_{t+2}=6.12[/tex]
