In order to determine the product platform and modularize for product family design , the quantified design structure matrix ( dsm ) is constructed based on the functional and structural interface relations analysis , which is aimed at the commonality and replaceable characteristics of product family , then the relations information is handled and sensitivity analysis is applied 摘要為解決產(chǎn)品族設(shè)計中的模塊化和核心平臺的確定問題,本文針對產(chǎn)品族的產(chǎn)品相似性和零部件的可替換性等特點,從功能和結(jié)構(gòu)兩個層次進行界面關(guān)聯(lián)并構(gòu)建量化的設(shè)計結(jié)構(gòu)矩陣,然后進行信息處理和部件的敏感性分析。
