Abstract: In this research, we studied the causes and effects of the factors that determine the trend of employing Common Platforms (CP) in Supply Chain Management (SCM) of automotive industries. Moreover, we proposed a framework for analyzing Supply Chain Based on Common Platforms (SCBCP) in industries. The research methodology of this study is based on fact finding approach. Therefore, presenting the definitions and concepts of pertinent subjects, a conceptual model is developed for determining various aspects and finding facts regarding SCBCP in automotive industry. Critical factors and important facts in SCBCP have been identified by developing and analyzing the conceptual model. In addition, a triple performance criterion for the evaluation of SCBCP is developed. This study is one of the first to present a framework for SCM based on CP. The main research questions behind this study concern the following three main aspects: understanding, describing and guiding how we can apply supply chain based on common platform in auto industry.
