Towards greener petrochemical production: Two-stage network data envelopment analysis in a fully fuzzy environment in the presence of undesirable outputs
作者：
Highlights：
• We evaluate two-stage production networks in a number of petrochemical companies.
• We use a fuzzy linear programming model with the presence of undesirable outputs.
• Our model also includes a two-stage network data envelopment analysis model.
• We think this is the first study to develop and apply a model with the above features.
• Our contribution to practice: better evaluation of efficiency in petrochemical plants.
