Abstract
Port information system plays an important role and crucial significance in port operations in general and container terminals particularly. Nowadays, 16 container terminals operating in Haiphong Port have a massive influence on the import and export procedure of the local and the whole nation, but the performance and competitiveness of the whole port still limit due to the non-uniformity and independence of using port information system. The research aims to determine factors impacting on using port information system in container terminals in Haiphong Port by a combination between Technology Acceptance Model (TAM) and Analytical Hierarchy Process (AHP). With a questionnaire survey of 21 experts from stakeholders related to using port information system, the result collected from software R shows 03 factors (levels of output quality improvement, individual demand suitability, and easy usage) have bigger impacts, whereas the social tendancy is opposite. It is a basis to propose measures stimulating the usage of port information system in next research.
