Research On Knowledge Representation And Reasoning For The Product Configuration

With the continuous increasing of the special needs of individual customers, knowledge-based product configuration design has recently attracted a lot of industrial interest. In this paper, several methods of knowledge representation and knowledge reasoning pertaining to air-nailer configuration are proposed. An overview of research contents and results in the dissertation are listed as follows:Firstly, with analyzing the advantage and disadvantage of configuration methods in the field of air-nailer, two methods of knowledge representataion are proposed: object-oriented constraint based method for structure module, and case based method for function module.Secondly, a kind of extended constraint satisfaction problem is developed and researched, for the purpose of improving the ability of control in the process of configuration reasoning.Thirdly, a kind of similarity evaluation method is developed based on the character of air-nailer, which convenients user for configuration reasoning in function-level.At last, an air-nailer product configuration system frame is designed and implemented by integrating both the advantage of constraint based and case based configuration. It has good result in practice.
