Abstract
Owing to the fast technology changing, non-profitable organization or government can use Internet to supply services. However, facing with users with different background, the main target for this system programmer is to design a complete set of interface to meet all kinds of users’ requests. The Accounting Purchase Network System used in all universities nationally faces various users with different background. There is differences on the users’ understanding and operation habits, which results in the difficulty to find out the operation problems by using human interface analysis. Through publications, we can understand that the improvement of user interface should take “meet the users’ requests” for the 1st priority. And in order to enhance the system efficiency, through Association Rules to find the most frequent operation interface in use, then to analyze the association between operation interface and users. This paper takes the user interface of some university as original record database, and utilizes Association Rules to dig out the association between users and user interface. Based on the result to propose improvement plans. In order to confirm these plans, this paper compares the process timing before and after improvement and uses questionnaire to analyze if less process timing and users’ requests is met. After verification, the plans really shorten 1/2 or 1/3 process timing and meet users’ requests.Keywords：Accounting Purchase Network System、Association Rules、Operation Interface
