DEA-Based Organizational Efficiency Evaluation of Unmanned Construction in Drill-and-Blast Tunnels
摘要
Abstract
To address the efficiency evaluation of organizational management in unmanned construction of drill-and-blast tunnels,an evaluation system based on the super-efficiency Slack-Based Measure(SBM)model with undesirable outputs was constructed.Taking a tunnel under construction in the Xizang Autonomous Region as a case study,an evaluation index system comprising four input indicators and four output indicators was estab-lished,wherein the overbreak volume was treated as an undesirable output.The evaluation of 30 construction cy-cles revealed that the average efficiency value was 0.988,with 66.67%of the cycles being DEA-efficient.The sub-process scheduling time and advance distance per cycle were identified as the most critical factors influenc-ing the organizational efficiency.Furthermore,construction cycles at different efficiency levels exhibited signifi-cant sensitivity stratification characteristics,indicating the presence of a diminishing marginal effect in efficiency improvement.关键词
