【摘要】：针对并行产品开发中上下游活动间存在重叠且重叠时间量化困难的问题,从知识的角度提出运用函数度量上下游活动的知识势和知识阻,基于知识难度系数构建知识势函数,并运用学习曲线理论构建知识阻函数,进而结合二者和知识欧姆定律以获得知识流函数;根据知识返工概率函数,计算下游活动重叠期的知识返工时间,进而构建上下游活动重叠时间的数学模型。最后通过实例验证了该方法的有效性与可行性。
[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.
