产品全生命周期基因工程理论框架研究

Based on rapid growth design theory and software prototype DARFAD for mechanical product, Product Genetic Engineering (PGE) concept is introduced in this paper, and expended to the whole physical life-cycle of products, especially to production phase, to have established the concept of Product Life-Cycle Genetic Engineering (PLCGE) and a basic framework for PLCGE theory. It is proposed that the product development can be divided into two main phases: product genome generation and product genome growth into physical form. In the former phase, product genome originates from and serves as an extension to human genome, and forms a complete genome through design process dealing with life-cycle factors. In the latter phase, the product genome acquires ‘protein’ to grow from its mother body ‘factory’, and PLM system acts as an umbilical cord between product genome and its mother body. Finally, PLCGE case is studied in a Mass Customization environment for an initiatory validation of the PLCGE theory.
