【摘要】：針對(duì)并行產(chǎn)品開發(fā)中上下游活動(dòng)間存在重疊且重疊時(shí)間量化困難的問題,從知識(shí)的角度提出運(yùn)用函數(shù)度量上下游活動(dòng)的知識(shí)勢和知識(shí)阻,基于知識(shí)難度系數(shù)構(gòu)建知識(shí)勢函數(shù),并運(yùn)用學(xué)習(xí)曲線理論構(gòu)建知識(shí)阻函數(shù),進(jìn)而結(jié)合二者和知識(shí)歐姆定律以獲得知識(shí)流函數(shù);根據(jù)知識(shí)返工概率函數(shù),計(jì)算下游活動(dòng)重疊期的知識(shí)返工時(shí)間,進(jìn)而構(gòu)建上下游活動(dòng)重疊時(shí)間的數(shù)學(xué)模型。最后通過實(shí)例驗(yàn)證了該方法的有效性與可行性。
[Abstract]:Aiming at the problem of overlapping and overlapping time quantification between upstream and downstream activities in parallel product development, a knowledge potential function based on knowledge difficulty coefficient is proposed to measure the knowledge potential and knowledge resistance of upstream and downstream activities from the point of view of knowledge. The knowledge resistance function is constructed by using the learning curve theory, and then the knowledge flow function is obtained by combining them with the knowledge Ohm law. According to the probability function of knowledge rework, the time of knowledge rework in the overlapping period of downstream activities is calculated, and the mathematical model of overlapping time of upstream and downstream activities is constructed. Finally, the effectiveness and feasibility of the method are verified by an example.
