摘要
为研究非线性约束下有缺货和无缺货两种策略对再制造供应链系统动态行为的影响,建立了不可退货、供货受制于当前供货服务水平且回收产量受最大回收能力限制的更符合实际情况的非线性系统模型。依据混沌动力学原理和方法,借助相图对两种缺货策略下非线性系统的动力学行为进行了仿真分析;进一步采用分岔图和最大李亚普诺夫指数对比了不同缺货策略下逆向环节参数对系统行为的影响。数值模拟结果表明,无论系统中有缺货还是无缺货,非线性约束都不是导致系统产生复杂混沌行为的充分条件;此外,除再制造提前期外,其它参数处于不同范围时,有缺货和无缺货策略各有优劣,需要根据管理目标和参数取值,选择适当的缺货策略。
In order to investigate the impacts of two shortage policies, namely with and without shortage, on dynamic behavior of remanufacturing supply chain system under nonlinear constraints, a more realistic model is proposed based on constraints of forbidden returning, finite supply service level, and maximum recoverable capacity. According to the principles of chaotic dynamics, the dynamic behavior of nonlinear system under the two shortage policies is analyzed with the aid of phase diagram. Moreover, the influences of some backward parameters under different shortage policies on system dynamics are compared by bifur- cation map and the maximum Lyapunov exponent. Simulation results show that nonlinear constraints do not inevitably lead to the chaotic behavior no matter what shortage policy is applied. A system with shortage is not strictly superior to the system without shortage and vice versa, when the value of backward system pa- rameters changes, except as remanufacturing lead-time parameter. The appropriate shortage policy should be selected according to management objectives and the value of parameters.
