In order to streamline the procedure of data transmission in port and logistics industries, MOMAF introduced EDI systems as the method of data transmission of 19 documents 5 years ago. While operating EDI system, MOMAF has found the inconvenience and the inefficiency of using EDI systems in the field of requesting fast response. This thesis focuses on finding the possible fields of on-line processing system. The result of the paper presents that if data transmission area such as 'application for pilot'is changed to on-line processing method, the processing cost and time will be reduced compared with EDI processing method.
