Abstract
In engineering activities, engineers solve various kinds of problems. Most of these problems are routine problems that are easy to formalize and formalized knowledge is useful for these problems. On the other hand, there are complicated problems that is difficult to formalize all of the problem solving process. One of the useful information to solve such complicated problems is result of the similar problem solving process. In addition, later in such complicated problem solving process, most of the decomposed subproblems are able to handle as routine problems. In this research, we decide to use formalized knowledge and document information that represents the history of problem solving processes to support to solve both types of the problem. For that purpose, we propose a new knowledge management system that supports a user to solve the problem through document processing. In this support process, the system retrieves related documents for user's problems by using formalized knowledge and information retrieval techniques. After retrieving related documents, he/she modifies them to fit his/her problems. Modified information is associated with the formalized knowledge and stored as documents for future reuse.
