基于绩效对比的三层生产-分销系统批量策略

针对包括生产商、区域配送中心(RDC)和分销商的三层生产-分销系统,研究了考虑货物进出RDC的批量对系统的影响.首先利用基于时间基准的最大公约数法优化生产-分销系统模型,求得固定批量策略,在此基础上探讨生产-分销过程中各种可能的情景,得到多重混合批量策略.定义了一个绩效对比标准,依据此标准对固定批量模型和多重混合批量模型进行求解.以中石油东北化工销售公司的部分数据作为计算实验的来源,结果验证了绩效对比标准和最优批量模型的有效性.

Lot-Size Policies in 3-Stage Production-Distribution System Based on Performance Contrast

Aiming at the 3-stage production-distribution system composed of producers， regional distribution centers (RDC) and distributor， the RDC lot-sizing policy was studied. First， the great common divisor (GCD) was taken as an adapted time base to optimize the production- distribution system model， and then the stationary policy was obtained. Different scenes in production-distribution process were discussed to obtain the multiple lot-sizing policies. The performance contrast standard was introduced to uncover the stationary lot-sizing model and the multiple lot-sizing model. The numerical experiments were conducted with the data from the Northeastern Chemical Sales Company of the PetroChina. The results confirm the validity of the standard and the model.
