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,multisuppliers 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.
