Vraaggenerator voor een distributieketen.
Report 92.3.LT.2950, Transport Technology, Logistic Engineering.
In a distribution chain three levels can be distinguished: the distributor,
the retailer and the consumer.
The final demand of the consumer can follow three types of patterns:
The size of the final consumers' demand is seen as normally distributed. There
can be a hidden stock at the retailer. Through these two facts, it is not
easy to forecast the demand at the distributor.
- a constant demand;
- a demand with a trend component;
- a demand with a seasonal component.
With the help of a demand generator, developed in the ESPRIT-project, it is
possible to forecast the demand at the distributor. This demand generator is
translated from C++ into Turbo Pascal 6.0. The program is supplemented in such
a way that seasonality can be taken into account.
The number of periods in a year can be adjusted. Every period is given an
indexnumber which reflects the ratio of the demand in that period and the
At this way seasonal corrections can be applied on the generated final demand
of the consumer. Next the seasonal demand at the distributor can be generated
