Evaluation of the efficiency of logistics activities using Data Envelopment Analysis (DEA)

Abstract This study aimed to analyze the efficiency of activities related to logistics modes, transport and cargo handling in Brazil. The theoretical framework was composed of the logistics efficiency and of the discussion of the characteristics of modes of transport and of variables related to efficiency. The study was classified as descriptive and quantitative, using the technique of data envelopment analysis. As main results, the ancillary activities to air transport stand out as efficient, which reached scores of 100% in the analyzed periods, except in 2010, in which they obtained 91.58%. It is worth noting that the activities cabotage and long-haul and ancillary activities to land transport achieved three maximum efficiency scores. In addition to evaluating the benchmark for the activities of lower efficiency score, the study also included improvements needed for other activities to achieve maximum efficiency. Finally, the central contribution of the article lies in the proposition of a multimodal analysis model.摘要 本研究旨在分析巴西境内与物流模式、运输及货物装卸相关活动的运行效率。本研究的理论框架涵盖物流效率相关内容、运输模式特征探讨以及与效率相关的变量分析。本研究属于描述性定量研究，采用数据包络分析（Data Envelopment Analysis）技术。主要研究结果显示，航空运输辅助活动的运行效率表现突出，在考察时段内均达到100%的效率得分，仅2010年为91.58%。值得注意的是，沿海捎带运输、长途运输以及陆路运输辅助活动均取得了三次满分效率得分。本研究除为效率得分较低的活动评估了标杆参考对象外，还提出了其他活动达成满分效率所需的改进路径。最后，本文的核心贡献在于提出了一种多式联运分析模型。
