Based on binary comparison, a kind of algorithm is presented for resolving the objective weight and relative membership degree of qualitative objects using fuzzy value of relative important degree of adjacentobjects.

The paper first designed the relative importance questionnaire based on the support of course to training target,then defined the course weight based on the course property,content,combination mode and cognitive law,and applied the duality contrast principle to define the importance of every course in the curriculum system.

Then the index system of it is set up and the weights of the indexes are made by using the method of two elements contrasting, based on which, a four-stage fuzzy comprehensive evaluation model is established and applied to assess the comprehensive benefits of an ITS project.
