Abstract
This paper discusses the restructuring of a knowledge-based system as a particular use of a decision table modeling tool. The aim of this exposition is to apply the approach in a real world application, SEAR (an Enterprise Human Resources Advisory System). All problems in restructuring the Knowledge-Based System (KBS) will be analyzed. It will be shown how a decision table tool is an interesting alternative in this process that facilitates the maintenance. First, the real world application is given and its current structure is shown. Next, the restructuring process is applied to the application. A summary that contains the obtained results and a brief evaluation conclude this paper.
