Abstract: To solve the problems of formula updating, repeated formula coding, difficulty of knowledge reuse and disordered parameters, the calculation formula was extracted from the source program of engineering design system and an algorithm-type knowledge management system was designed to deal with it. In the algorithm-type knowledge management system, the basic objects were parameter, algorithm expression and formula. The algorithm expression knowledge was described, and its operation technologies in knowledge management system were probed, such as knowledge augmentation, deletion, modification, view, inquiry, as well as grammar effectiveness checking, uniqueness checking, conformity checking, structural effectiveness checking and conflict checking. Formula transformation technology of knowledge management system to intelligent design system was studied. The algorithm-type knowledge management system was developed and applied in designing system of air-conditioning compressor.

Key words: intelligent design, knowledge management, algorithm expression formula, knowledge base
