In terms of limitations , there are difficulties for a single logistics company to utilise DSS because of lack of information provided for the database. This DSS database is in need of agreat number of updated data on all routes and modes between Thailand and Vietnam such as costs of routes , time of transportation, the change of infrastructure and equipment of new route and law, etc. This DSS should be able to link the Thailand and Vietnam logistics associations that have a number of networks for updating data in the database. Both associations should maintain and update in formation in DSS.
