中文摘要：

为减少原料库存巨额的资金占用,研究了多品种多供应商随机提前期环境下的精确库存成本建模问题,给出实时成本统计分析与计算的方法,建立了精确的多品多供应商随机提前期库存成本函数的数学模型,并对＂保证供应、均匀到港＂等约束给出了数学上的形式化表示。分析了再订购点取值问题。最后,利用智能方法对模型进行优化和仿真,分析了模型的性质,给出优化结果。

英文摘要：

To reduce huge amount of funds used for raw materials inventory,the exact inventory cost modeling with multi-items,multi-suppliers and random lead times was studied. The statistics analysis and calculation method for real-time cost was presented,and the exact mathematical model of inventory cost function with multi-items,multi-suppliers and random lead times was established. Constraints of overseas procurement,which were guaranteeing supply and arriving evenly were formally expressed. The reorder points of multi-items were also analyzed. Finally,the model was optimized and simulated by intelligent optimization algorithm. Model properties were analyzed and the optimization results were provided.
