運用模糊整合性存貨模式評估醫療衛材之研究

Using the Fuzzy integrated inventory model to evaluate for medical materials

存貨管理在企業之經營中扮演著重要的角色，而在醫療機構的營運成本結構中，包含藥品與醫療材料的資材成本約佔3-4成，然而醫療機構在經營業務上，有關資材管控項目卻經常被忽略。因此，本研究主要利用ABC分類法有系統地分類，再透過模糊整合性存貨模式進行求解，進一步產生具實用性價值的模式、改善訂購上的成本，求得最佳經濟訂購量。經實證結果顯示A類（測試咬合壓力組）之傳統存貨總成本較聯合存貨總成本小，B類（印模粉）與C類（根管銼）所求得的聯合總成本較傳統存貨總成本小；即此表示B類與C類使用整合性存貨模式會優於傳統存貨模式。依據評估結果，提供中部某醫學中心醫藥部門之參考。

The inventory management play important role of the business enterprise, if it does not appropriate control cause inventory lack or too much will be reputation losing. In practice operation of medical material supply, that responsible to many different medical materials by a supplier is a common situation. In total operating cost, the handling cost of medical materials including purchasing and inventory is almost a 30%∼40% share for most of hospitals in Taiwan. However, the handling of medical materials was regarded as a relatively not important part in hospital administration in Taiwan. Thus, this research combined tradition ABC analytic method, using the Fuzzy integrated inventory model, the solution smallest cost and the optimal economical order quantity. The empirical results, A Type(test occlusion pressure group) of the total costs, compared with traditional inventory joint stock small combined total costs, B Type(stamp powder) and C Type (endodontic file) of the total costs, combined total costs compared with small traditional inventory joint stock. This represents B Type and C Type using integrated inventory model will be better than the traditional inventory model. Finally, the management implications and further research are proposed based on the research results.
