Final Answer:
Global DEA (Data Envelopment Analysis) is typically measured in relative efficiency scores, a dimensionless ratio indicating how well a unit (such as a firm or organization) utilizes its inputs to generate outputs.
Step-by-step explanation:
Global DEA is a mathematical technique used in operations research and management science to evaluate the efficiency of decision-making units. It assesses how effectively a unit transforms multiple inputs into multiple outputs. The output of a global DEA analysis is a set of efficiency scores, with a score of 1 indicating perfect efficiency.
These efficiency scores are relative, comparing the efficiency of each unit to others in the analysis. A score of less than 1 suggests inefficiency, while a score of 1 denotes full efficiency. Global DEA is employed in various fields, including finance, healthcare, and public policy, to enhance decision-making processes.
