The weight constraint logic program can represent the product configuration knowledge well, and can quickly finger out the solution when the program has solutions. Actually, sometimes, users do not have professional knowledge, or their requirements are out of the scope of configuration, thus, the users’ requirements can’t be satisfied and no solution can be obtained. For finding the most satisfactory solution, this paper proposes a weight quantitative method to compute the satisfactory solution, and makes a comparison with other relational work.
