SUPPLIER EVALUATION IN A DYADIC RELATIONSHIP: AN ACTION RESEARCH APPROACH
描述了一个应用于电信公司供应商评估环境的行动研究框架，使用数据包络分析来协调评估输入并展示二元相互依赖关系。
This article describes an Action Research (AR) framework applied to the supplier evaluation environment of a telecommunication company. Within this AR framework, data envelopment analysis (DEA) was used because the methodology can successfully delineate evaluation problems and then outline a desirable path. This leads management to continuously review and improve complex systems or processes. The DEA methodology coordinates the supplier evaluation inputs and reconciles what can be very diverse performance measures and even more diverse weights applied by evaluation team members. Finally, dyadic interdependence can be demonstrated by identifying the impact of changes in buyer performance attributes on each supplier's capacity to accommodate and adjust.
