3.3.1. Results before Alliance

In this study, the authors used the Super-SBM model to evaluate efficiency and rank the logistics enterprises in Vietnam in the period of 2019–2020. The results show that, even during the pandemic, there are still businesses that operate very effectively: RankLO4 = 1 (ScoreLO4 = 3.2525), RankLO9 = 2 (ScoreLO9 = 1.5320), RankLO8 = 3 (ScoreLO8 = 1.3031). However, there are businesses that have been heavily affected by the COVID-19 pandemic, so their operations are not effective: RankLO2 = 9 (ScoreLO2 = 0.5554); RankLO3 = 10 (ScoreLO3 = 0.4432).

The authors used the results in Table 8 and Figure 12 as a basis for selecting enterprises to make alliances with other enterprises. If we choose businesses that have not achieved business efficiency in this period (LO2, LO3), it is difficult to convince other businesses to implement the alliance. Therefore, the authors have chosen LO10 (Vietnam container shipping joint stock corporation) as a target enterprise to engage in negotiations with other enterprises to implement alliances in order to realize strategic goals and support each other for mutual development. The authors chose LO10 as the target enterprise. In 2020, LO10 still had good business results: Rank LO10 = 5 (Score LO10 = 1.2242). LO10 in Hai Phong city was established in 1985, specializing in logistics and container agency services, shipping agents, warehouse business, yards, transport of import and export goods, cargo projects, goods in transit, and so on. When participating in negotiations to form alliances with other businesses, this enterprise will have many advantages and a high probability of success.
