Purpose: Evaluating the cost efficiency of a network system using Data Envelopment Analysis (DEA) models can be improved from various aspects that exist in real applications. In this study, the aim is to consider a specific set of weights to evaluate cost efficiency in a two-stage network system.Methodology: In this research, using data envelopment analysis method, an attempt is made to provide a model for evaluating the cost of the network system.Findings: The results showed that considering the relationships between different stages in a network system can directly affect the results. This issue has been investigated from cost optimization assessments. Considering the set of weights from different aspects can affect the scores obtained.Originality/Value: According to the models and methods in the literature, in this study, a model is presented that considers cost efficiency in a two-stage model.
