Data 1: Decision-Making Unit Performance Data for Centralized Efficiency Analysis

A dataset supporting a new mixed-integer nonlinear programming model for Data Envelopment Analysis (DEA). The model identifies a subset of k outstanding decision-making units from n units within a centralized system, eliminating predefined constants to guarantee feasibility and boundedness. The dataset, shared by Zahra Cheraghali on figshare under a CC-BY-4.0 license, was last updated in May 2026.

Use Cases

• Identifying high-impact decision-making units based on their collective contribution to system efficiency.
• Benchmarking performance of comparable units within a centralized organization.
• Validating centralized DEA models that avoid predefined constants to prevent infeasible optimization problems.

Strengths

• The dataset is associated with a model that guarantees feasibility and boundedness, addressing a known limitation in prior DEA approaches.
• The dataset is shared under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
