Data envelopment analysis (DEA) is one of the fundamental methods for analyzing the performance of a homogeneous set of decision-making units. Recently, DEA has been developed and applied to multi-stage processes. The essential feature of multi-stage processes is the presence of non-optimal intermediate outputs, which are usually not the final output of the system. This study used a new approach to analyze the reuse of non-optimal intermediate outputs in a two-stage production process with common resources. Ultimately, non-cooperative efficiency criteria were used to demonstrate unit efficiency. Finally, the unit under study is relatively inefficient from the perspective of the non-cooperative model related to the assembly and body production line of Iran Khodro.
