Abstract:

On the basis of hybrid dynamic system theories, a new and unified hybrid dynamic model for real inventory systems is proposed. The hybrid dynamic model evolves continnousvariable state spaces and discrete transitions, and this model characterices their changes and their interacting collection. This new model has strong capacity  because it could capture all kinds of discrete phenomena in inventory systems, and subsumes all previous models for inventory systems.

Key words: hybrid dynamic system; inventory management; mathematics model
