摘要
产品并行开发可以优化流程缩短开发周期。其中下游阶段工作启动时刻的确定是实施并行工程的关键。本文这里引入了信息熵的概念,提出了基于信息熵和利用B样条,结合模糊数学中多层次模糊综合评判方法,确定下游阶段事件启动时刻T0的算法模型,给出了求解该数学模型的方法,指出了该模型应用于实践的思路。
The determination of startup time T 0 of downstream phase is the key point in implementing CE programs. We use the concept of info entropy to present an algorithm for determining the T 0 of downstream phase based on info entropy and Bezier curve cooperated with the multi layer comprehensive decision making principle of fuzzy algorithm. A method is designed to solve the algorithm modeling.
