New method ensures accurate decision-making in data analysis for efficiency.
The article examines how stable efficiency scores are in Data Envelopment Analysis when data changes. A new method is used to measure the stability of decision-making units' efficiency while data varies. By calculating the allowable percentage change in data, the researchers can determine how much data can fluctuate while still maintaining efficiency. The study shows that this modified technique can help in making more reliable decisions when analyzing efficiency.
