Combination of Top-down and Bottom-up DEA models using PCA: A Two-Stage Network DEA with Shared Input and Undesirable Output for Evaluation of the Road Transport Sector
Socio-Economic Planning Sciences. 2023. Vol. 89. Article 101706.
This paper presents a network data envelopment analysis (NDEA) model to assess road transport sector by considering energy and non-energy inputs, shared input, and desirable and undesirable outputs. The sector is considered as a two-stage framework where in stage 1, energy-environmental efficiency is calculated and in stage 2, technical efficiency is estimated. There are two general approaches for evaluation of the network structures using NDEA models: bottom-up and top-down. In the bottom-up approach of this study, a goal programming NDEA (GP-NDEA) model is proposed to calculate the efficiency of the two stages at the same time and then overall efficiency is obtained using the results of the two stages. In the top-down approach, both non-radial SBM-NDEA and RAM-NDEA models are applied to calculate the overall efficiency and then the efficiencies of stage 1 and stage 2 are estimated using the results of the overall efficiency. Three different models GP-NDEA, SBM-NDEA, and RAM-NDEA lead to different results and to obtain the final efficiencies and ranks, principal component analysis (PCA) method is applied. The efficiency generated by different bottom-up and top-down approaches are considered as indicators in PCA, and the final scores for both stages are calculated using PCA. To illustrate the capability of the proposed approach, an actual dataset of road transport sector in provinces of Iran is gathered and the results of the different models are analyzed.

В данном исследовании рассматривается связь между интеллектуальным капиталом компаний и их интернационализацией в условиях внешних шоков. В отличие от предыдущих работ, как правило, рассматривающих взаимосвязь интеллектуального капитала и интернационализации в стабильной экономике, в исследовании развиваются предположения о неоднородном влиянии шоков на компоненты интеллектуального капитала и, соответственно, различном модерационном эффекте шоков на трансформацию интеллектуального капитала в экспортную ...

Abstract. Long-standing differences in development levels between China’s coastal and inland provinces intensified during the 1980s–1990s, at the early stages of market reforms. In response, from the late 1990s the Сentral government began implementing major development initiatives such as the “Go West”, the “Revitalization of the Northeast,” and the “Rise of Central China,” while in ...

Enterprises planning material requirements must account for multiple sources of uncertainty. Considering the impact of yield uncertainty is of prime importance to decision-makers. To mitigate the effects of random yield on the continuity of manufacturing operations, we propose establishing a reserve stock to prevent shortages due to defective items within safety stock levels. If no ...
