چکیده [English]

Purpose: The providing a proposed model pair for ranking interval data and their application to evaluate and improve the performance of a service system using results of simulation.
Methodology: Mathematical techniques (data envelopment analysis) and computer simulation.
Findings: By presenting proposed models pair, we were able to improve the performance of a service system by simulating different scenarios for that system. The results show that the introduced scenario could increase the efficiency of system by 22%.
