Abstract
The information system of undergraduate training program can reduce the tedious labor, and has great significance for implementing the engineering education professional accreditation. Based on the polychromatic sets theory, the information model of undergraduate training program was constructed and described formally from horizontal and vertical directions. The reasoning algorithm of information model was proposed and the related knowledge of undergraduate training program was reasoned automatically in logic layer. The proposed information modelling and knowledge reasoning method of undergraduate training program has some obvious advantages for supporting engineering education accreditation.
