| 概要≠ | Epsilon-Based Measure DEA (EBM-DEA) is a non-parametric efficiency analysis method that evaluates how efficiently organizational units convert inputs into outputs. Unlike simple ratio-based methods, EBM accounts for slacks (unused inputs, unmet outputs) proportionally in both input and output dimensions. It produces a single efficiency score between 0 and 1, with 1 indicating best-practice efficiency. | DEA (Data Envelopment Analysis (CCR model) for efficiency-based ranking) is a dea multi-criteria decision-making (MCDM) method introduced by Charnes, A., Cooper, W. W., Rhodes, E. in 1978. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result. |
