Simple Moving Average ${}_t=\frac{A_{t-1}+A_{t-2}+A_{t-3}+A_{t-n}}{n}$

Weighted Moving Average $F_t=w_1{A}_{t-1}+w_2{A}_{t-2}+w_3{A}_{t-3}+$dots$+w_n{A}_{t-n}$

Exponential Smoothing $F_t=F_{t-1}+a(A_{t-1}-F_{t-1})$

Forecast Error MAD$=\frac{{\displaystyle \underset{t=1}{\overset{n}{}}}|A_t-F_t|}{n}$

$F_t=$ Forecast value for the coming $t$ time period $,F_{t-1}=$ Forecast value in previous time period

$A_{t-1}=$ Actual demand in previous time period

$w_t=$ weight factor for previous time period
