With the max imum satisfaction, gi en to both know ledge demand and supply, and the maximization of intermediary interests in know ledge ser ice taken as the objecti es, a mult-i objecti e bilateral matching optimization model was de eloped. Furthermore, the weighted sum based on membership functions w as used to transform the multiobjecti e optimization model into a single objecti e one to which the solution offered the bilateral matching results. A numerical example is gi en to illustrate the feasibility and alidity of the bilateral matching model thus proposed.
