摘要

Medical waste is a waste derived from healthcare and other such medical activities. If there is no medical waste management or if that management is inadequate, there might be higher risks of infections and hazards because some of the waste can be infectious, containing toxic chemicals and posing contamination risks to both people and the environment. In order to have a good medical waste treatment, most medical institutions outsource their waste treatment to waste disposal firms. Selecting the right logistic firm is a critical issue to the medical institutions. To a medical institution, there are several different criteria to be considered when selecting a logistic firm. In addition, some of these multiple criteria usually have conflicting decision objectives. Therefore, the selection of the medical waste logistic firms is a multi-criteria decision-making (MCDM) problem. Several MCDM methods have been proposed in the literature. This study proposes an evaluation model to rank the priorities of potential logistic firms based on their properties using vlsekriterijumska optimizacija i kompromisno resenje (VIKOR) and analytic hierarchy process (AHP). This approach should increase the level of satisfaction after selecting the logistic firm. The working of the proposed model is illustrated with a numerical example.

醫療廢棄物一般來自健康照護及醫療行為，該等醫療廢棄物可能受到汙染而含有毒性化學物質，如果未加以管理或管理不完善時將對吾人帶來感染疾病或汙染環境的危險。為使醫療廢棄物能有較好之處置，大多數醫療機構都將其外包給專業廢棄物物流處理廠商來處理。對醫療機構而言，如何選擇良好的廢棄物物流處理廠商是個非常重要的問題。當選擇廠商時有好幾種不同評估準則需同時考慮，因而是個多準則決策問題，而該等準則對於決策目標有時甚至彼此相互衝突。文獻上已探討多種多準則決策方法，本研究以可處理評估準則之間相互衝突並產生最佳妥協解的用折衷排序法(vlsekriterijumska optimizacija i kompromisno resenje, VIKOR)結合層級分析法(analytic hierarchy process, AHP)對符合基本條件之物流廠商，依其特性表現彙整後加以優劣排序，以做為選取廠商之參考，因而可以增加廢棄物物流處理廠商選取後之服務滿意水準，同時本研究以數值例說明模式如何應用。
