供应商的选择,就是找到能够以合理价格及时、足量提供产品或服务的卖方,是建立一个有效供应链至关重要的环节,也是一个很复杂的问题,因为供应商的选择通常是一个多目标群决策问题,这往往会存在两个问题:多个目标的冲突和决策者对信息的不明确。在该文中采用逼近理想解排序法(TOPSIS)与直觉模糊集相结合,在群决策中选择适当的供应商,用直觉模糊加权平均(IFWA)算子来评价决策者个人意见及各个方案的重要性,最后,通过一个选择供应商的算例来阐述直觉模糊TOPSIS方法的应用。
The vendor’s choice is to find a seller who can offer a product or service on time and in sufficient quantities at a reasonable price. It is also a crucial part of building an effective supply chain. It is also a complex issue because the vendor’s choice is usually more than one There are often two problems with the decision-making of the target group: the conflict of multiple goals and the uncertainty of the decision makers. In this paper, TOPSIS is combined with intuitionistic fuzzy sets to select the appropriate suppliers in the group decision-making. The intuitionistic fuzzy weighted average (IFWA) operator is used to evaluate the personal opinions of decision-makers and the importance of each scheme Finally, we illustrate the application of the intuitionistic TOPSIS method through a selection of suppliers.
