研究不同需求模式下,同时存在供应能力限制和不允许退货两个约束条件的非线性供应链系统的动态行为.通过计算订货决策空间中各种组合下的最大李雅普诺夫指数,比较分析不同情景模式供应链系统的准混沌行为.研究表明,受约束条件影响的供应链系统具有相对复杂的动态特征,但并不是无规律可循,即使在随机需求模式下,若订货策略合理,则仍可减轻甚至避免系统的混沌行为;反之,在稳定的需求模式下,不合理的订货策略仍会导致系统处于混沌状态.仿真实验验证了研究结果的合理性.
This paper studies the dynamic behavior of the nonlinear supply chain system under the constraints of supply capacity and non-return, under the different demand modes.According to the maximum Lyapunov exponents of various combinations in the order-decision space, the different scenarios The research shows that the supply chain system affected by the constraints has relatively complex dynamic characteristics, but it is not irregular to follow. Even in the stochastic demand mode, if the ordering strategy is reasonable, Reduce or even avoid the chaos of the system; on the contrary, in the steady demand mode, the unreasonable ordering strategy will still cause the system to be in a chaotic state. Simulation results verify the rationality of the research results.
