ABSTRACT
In this paper, the linkage of two different concepts;sustainable competitive advantage (SCA) and Supply Management (SM) are analyzed. SCA has been gaining attention in last decades. Companies have been trying to obtain SCA in order to be successful and keep their position in the future. As competition intensifies among enterprises, each enterprise seeks to research how to reduce costs and/or achieve excellence compared to competitors in the market. One of the areas that the enterprise can exploit to achieve a sustainable competitive advantage is the supply chain. Supply chain management (SCM) philosophy is based on collaboration of suppliers, manufacturers and distributers. SM is a vital part of SCM and SM has been gaining importance in the last decades according to several factors. Sustainable SM activities may provide supply chain SCA from many aspects. It is argued that Supply Management (SM) is linked with performance and effects on SCA directly or indirectly. In this chapter, the health systems vaccine supply chain performance activities were evaluated with DEA during the COVID 19 pandemic period, using the health indicators of European countries for January 2022 in Trading Economics and WHO databases. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
