Abstract： Constructing knowledge structures based on variable precision α -models is one of the current research hotspots. Three types of variable precision competence models based on fuzzy skill multimaps with different threshold value ranges were extended，and the properties of the knowledge structures constructed by the models were discussed. It was proved that the knowledge structure families constructed were consistent. Based on this，a matrix approach for constructing knowledge structures based on fuzzy skill multimaps was proposed，and the feasibility and effectiveness of the method were verified by experiments.Furthermore，how the numbers of problems and skils in fuzzy skill multimaps affected the method's running time and space complexity was discussed.

Key words： knowledge space; knowledge structure; fuzzy skillmultimaps; variable precision competency model
