In order to run the model properly, there is a need to
obtain the Vd (from the forecasting model) which later
can be calculated to be the total demand (Cd). The
forecasting models available are, for example, Simple
Moving Average, Weighted Moving Average,
Exponential Smoothing etc. (see detail in [18]). If there
is absolutely no previous data to be forecasted, one can
use the expected market demand from a Marketing
Department. On the other hand, if previous data is
available, one of the forecasting models can be applied.
Then, the model can draw a result which an illustrated
result can be seen in Table 1.
