Knowledge reuse of multi-hierarchy case based on axiomatic design

To improve efficiency for large-scale complicated product design,the case decomposition and reuse of scheme design knowledge were studied,as well as a case reuse method based on Axiomatic Design(AD) was proposed.With this method,decomposition interaction was firstly applied in multi-hierarchy case decomposition to build the multi-hierarchy case model.Knowledge reuse model was put forward based on multi-hierarchy case database to achieve case reuse.An example of large-scale hydraulic turbine scheme design was provided to validate the effectiveness and feasibility of the proposed method.
