4.2 Result of Different Algorithms
We can see from the results that using hybrid NSGA-II, we can have more cen-
tralized result (comparing Fig.3 to Fig.2), especially when the cost is high. This
verifies that Hybrid NSGA-II based on the problem can have more satisfactory
results than the ordinary NSGA-II.

This paper focuses on mainly inventory and the risk in it. We built a bi-objective
model, and examined several approach to solving it. Particularly, this paper in-
troduces a serial hybrid NSGA-II algorithm which is based on problem property.
Through simulation, we verified the feasibility and eciency of our model and
algorithm.
