卷烟包装箱回收物流系统调度优化模型

为优化烟草行业包装箱回收工作，结合烟草行业包装箱回收物流过程的特殊性，针对卷烟工厂、卷烟包装箱回收中心、卷烟商业地区性配送中心构成的闭环物流系统网络，将卷烟工厂生产计划所需包装箱需求、卷烟包装箱回收过程中各环节的回收合格率、包装箱处理检测费用、处理中心回收能力、各环节之间单位运费等因素引入模型，建立了总成本费用最小的卷烟包装箱回收物流系统调度优化模型，结合实际案例数据，利用优化软件CPLEX得到其最优调度方案，并对影响优化方案的两个关键因素进行了分析。研究结果表明:利用包装箱回收物流系统调度优化模型可提高企业的经济效益，回收的包装箱合格率越高，回收经济效果越好；回收环节处理的成本越高，回收包装箱越没有价值。 

Optimized scheduling model for logistics system of reclaimed cigarette cases

To address problems in closed loop logistics system composed of cigarette factory, recycling center and distribution center of tobacco companies, the optimal scheduling model for recycling logistics system of cigarette cases was established at the lowest cost by taking into account the cases demand, recycling pass rate, processing and detection costs, recycling capacity of processing center and transportation cost between different points of the processing link. Based on actual case data, the optimal scheduling scheme is obtained by using optimization software CPLEX and two key factors influencing the optimization model were analyzed. Results showed that the higher the rate of the reclaimed cigarette cases, the better economic efficiency; the higher the cost of recycling operations, the less significant the recycling program.
