The integration of SD and DES models allows the
simulation of the value chain. Figs. 9–11 show the
simulation results for the profits, customer satisfaction,
and responsiveness, respectively, for all three
alternatives. These figures show that all alternatives
could lead to good growth rates. However, alternatives
A and B are more preferred than alternative
C with respect to profitability (see Fig. 9). The
expected customer satisfaction of alternative A is
the worst, while either of the other two alternatives
has acceptable expected customer satisfaction (see
Fig. 10). On the other hand, the expected replenishment
time of alternative A is the most desired,
while those of the other two are relatively large
(see Fig. 11). The obtained simulation results are
provided for the decision makers to be employed in
the group decision making process using stochastic
AHP methodology.
