Measuring the success level of public-private partnership transportation infrastructure projects in vietnam using fuzzy topsis method

Public–Private Partnership (PPP) has emerged as an effective procurement in delivering infrastructure and public service in many countries over the world since last few decades. It brought more benefits for sustainable development compared to traditional procurement in many developing countries. However, in order to determine whether a project is successful or not has still remained an ambiguous perception. Therefore, this study will rank the successful level for PPP transportation infrastructure projects in Vietnam via case studies. Fifteen success criteria were identified by the comprehensive review. The fuzzy TOPSIS method was then applied to evaluate and rank the success level for case studies. The result showed that project 2 is considered as the most successful until this recent time with a satisfactory degree of 0.489. Project 1 and project 3 are ranked second and third with a satisfactory degree of 0.482 and 0.435, respectively. Although the projects were judged as effective. Nevertheless, the success index of these expressway project still lower than 0.5. Therefore, project managers need to propose effective solutions to improve the success of these projects in the future. This result can help participants to be a good insight into the PPP project success in developing countries in general and Vietnam in particular.
