Integrating the Additive Seasonal Model and Super-SBM Model to Compute the Efficiency of Port Logistics Companies in Vietnam

Abstract

The growing trade process is pushing the importing and exporting ratio of products at ports in Vietnam. The total amount of goods is determined by analyzing the effectiveness of products that are delivered at ports. Thus, this research presents a whole performance picture of the port logistics operation process at two airports and six seaport logistics companies in Vietnam to describe exchanging products by utilizing additive trend methods to formulate the efficiency and rank them from previous periods to future terms. Based on the prediction analysis, the best accuracy result is calculated by the additive Holt Winters method when the mean absolute percentage error (MAPE) indicators remain at the standard level, and its average qualification is also the lowest. Combining the actual and prediction values, the ranking of all ports accordingly by year during the past, current, and future time periods from 2011-2022 is obtained after calculating the final efficiency via the super-SBM model. The empirical result of the current and estimated efficiency denotes that Da Nang port logistics is always selected as the best port logistics company and maintained the first ranking with consistently high scores on the basis of the performance qualification. The empirical analysis result proposes the status quo of port logistics companies in Vietnam from the past to future to describe the amount of exchanging goods.

Logistics Efficiency under Carbon Constraints Based on a Super SBM Model with Undesirable Output: Empirical Evidence from China’s Logistics Industry

“…As compared to other DEA models, this super SBM model, while considering undesirable outputs, solved three problems that have existed in previous efficiency evaluations [45]: first, the undesirable output factors were included in the analysis category; second, the relaxation of input-output variables was effectively solved; third, the problem of multiple decision-making units appearing simultaneously at the forefront and unable to be effectively ranked was solved. Therefore, the model (2) could measure and evaluate the efficiency of regional logistics comprehensively [46].…”

An Integrated Approach of Fuzzy Analytic Hierarchy Process and Super Slack-Based Measure for the Logistics Industry in Vietnam

“…The DEA method with efficiency calculation presents the performance of a decision-making unit (DMU) once the ratio of inputs and outputs are calculated. Wang et al (2018) [22] implemented the measurement of efficiency scores of port logistics companies in Vietnam via the super-SBM model. Marto et al (2022) [23] applied DEA optimization to present the performance of GDP per capital in EU regions.…”

“…Subsequently, Banker et al [28] extended the DEA model to cover variable returns to scale (VRS). Since then, DEA models have been extended to other practical domains in the form of super-efficiency models [29][30][31], cross-efficiency models [32,33], SBM models [34,35], super-SBM models [36,37], and network DEA models [38][39][40].…”
