库存系统的统一混合动态模型

A unified hybrid dynamic model for inventory systems

在混合动态理论的基础上对于实际存货系统建立了新的统一的混合动态模型.该模型中既含有连续变量又含有离散变量,并且有刻画它们变化及其相互作用的数量关系.该模型的统一性是指其具有很强的包容性,不仅可以包容库存系统中所出现的各种各样的离散现象,而且可以包容先前所建立的各种关于存货系统的数学模型.

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 continuous-variable state spaces and discrete transitions, and this model characterizes 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.
