Answer:

The smoothing constant alpha is 0.20 (Option a)

Step-by-step explanation:

To solve this problem, first we write the succession of the simple exponential smoothing:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}$

Where s(t) is the forecast for period t, s(t-1) is the forecast for period (t-1), xt is the real demand for period t, and alpha is the smoothing constant.

All but the alpha constant are known

s(t)=109.2

s(t-2)=110

xt=110-4=106

Then, we can calculate alpha as:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}\\\\109.2=\alpha*106+(1-\alpha)*110\\\\109.2=(106-110)\alpha+110\\\\(110-106)\alpha=110-109.2=0.8\\\\4\alpha=0.8\\\\\alpha=0.2$
