Abstract: We first analyzed the relationship between mass customization and product configuration, and the present condition, research contents, knowledge representation of product configuration not only from the applicati on point of view but also from the theoretical research one. On the basis of the facts described above, we proposed the graphbased knowledge representation of configuration, moreover, we pointed out the methods to lowering the complexity of configuration computation and improving the efficiency of configuration solving, and the application prospects of configurators.

Key words: mass customization, product configuration, product configurator, knowledge representation of configuration
