向多个供应商采购的存贮模型研究

本文研究当需求量巨大、单一供应商无法满足供货要求情况下的多供应商采购-库存问题，建立了一个向多个有能力约束的供应商采购的库存模型；将模型简化以后用Kuhn-Tucker条件分析了其松弛问题的最优解的必要条件及其相应的搜索算法；随后给出了模型的整数近似解算法，最后给出本文结论以及未来的研究方向。

The Research on the Inventory Model of Placing Orders with Multi-suppliers

This paper focuses on the multi-suppliers purchasing-inventory problem when the demand is tremendous and a single supplier can't meet the demand. An inventory model placing orders with multi-suppliers with capacity constrain is established. By applying Kuhn-Tucker condition after the model is simplified, the theorem of optimal solution existeuce condition of slack problem is proved and the corresponding searching algorithm is given. The integral approximate solution algorithm of the model is given too. Finally, conclusions and potential areas for future research are present.
