Abstract: To improve the response speed of customer's request and to increase the estimation accuracy of cost, the technology for product modules based on structure transplantation was put forward. Multi-level analysis of product modules was implemented and model of Modular Structure Element(MSE)was built. Through the rule-based multi-level search, the transplanted MSE was obtained and virtual module was generated by MSE transplantation. According to the mapping of transplanted MSE and process, the virtual module process route was obtained and process cost estimation was realized. The product virtual module cost was obtained by the composition of material cost and process cost. It provided a basis for product quotation. This technology was applied in the rapid quotation system of elevator product, and the speed as well as accuracy of cost estimation was effectively improved.
