在現今競爭激烈的經營環境中，企業求生存除了開源 — 創造財富，更重要的是節流 — 降低成本。企業常因存貨積壓過多而增加營運風險，甚至因此遭受損失。反之，過少的存貨又會造成顧客需求無法滿足，導致顧客流失及利潤減少的情形。因此在降低成本的首要考量之下，如何訂定一套有效的存貨管理系統以減輕存貨帶來的壓力，方能提高企業之整體競爭力，為經營企業當務之急。
在供應鏈管理中，買賣雙方的關係，不單只有競爭；亦出現了合作的關係，因此若只單獨考慮如何減少買方成本或是單獨增加賣方利潤，是不符合實際狀況的。應該是透過協商、合約的方式，發展出一套整合性的存貨模式，尋求最低聯合總成本，以達到供應鏈管理中「風險共擔，利益共享」的目的。
在2002年由Yang和Wee所提出〝單一賣方和多方買方具損耗性生產存貨策略〞，在其論文模式中提出一個近似的方法來搜尋求解最佳存貨，其近似解與實際之最佳解存在極大的誤差。
在2006年Wee等人雖然提出賣方的每年存貨持有成本模式錯誤之修正，但仍然未對近似解之誤差提出修正。
本論文重新探討此一具有實務應用的存貨模式，指出Yang和Wee論文中未加以詳細考慮之缺失，即其以啟發式演算法計算所得的週期時間解會無法適用目標函數之缺失，針對此缺失的原因修正改善，建立一完整的搜尋法求得最佳策略，使理論與實務應用更合乎實際。

In today's highly competitive business environment, enterprises survive in addition to revenue-creating wealth, but more importantly is to cut expenditure - to reduce costs. Enterprises due to excessive inventory backlogs increased operating risk, or even suffer losses. Instead, the stock is too small to meet the demands of customers would cause, resulting decrease in the loss of customers and profits. Therefore, the top priority of lowering costs, how to set an effective inventory management system to relieve the pressure brought about inventory, to improve the overall competitiveness of enterprises, the top priority for enterprises.
In supply chain management, vendor relations, not only competition; Is a co-operative relationship, and therefore if the buyer alone to consider ways of reducing the cost or increasing the profit alone is not consistent with the actual situation. Should be through consultation, contracts, develop a integrated inventory model, the search for the lowest total cost of the joint to achieve supply chain management "risk sharing, the sharing of benefits".
In 2002 Yang and Wee proposed by the "A single-vendor and multiple- buyers production-inventory policy for a deteriorating item." put in their theses as a model similar to the search for the best stock sits approximate solution and realism optimal solution there is a maximum error function.
In 2006 Wee et al although has issued the vendor's inventory anniversary holding costs error correction model then it still failed to propose amendments to the approximate solution of error.
This study is a practical application of this re-inventory model Yang and Wee theses that have yet to be considered in detail, mistakes that is, heuristic algorithms derived from the cycle time to be not able to apply solutions objective function, defect the reason for this improvements, to establish a comprehensive strategy to search for the best method to achieve, Application of theory and practice are more alike reality.
