对一台机器加工时间可控时的延误工件数问题，如何构造延误工件数和加工时间减少量之间的关系曲线，文献［１］给出了一些理论结果，但未给出具体算法，该文在恒为１的条件下，分析了文献［１］所获结果，证明了曲线上有效值的个数，并从考虑延误工件数出发在文献［１］基础上给出了构造上述曲线的具体算法。 How to construct the relationship between the number of delayed workpieces and the reduction of processing time when the machining time of a machine is controllable? Some theoretical results are given in [1], but no specific algorithm is given Under the condition of constant 1, the results obtained in [1] are analyzed and the number of valid values ​​on the curve is proved. Based on the literature [1], the structure of the above curve is given Specific algorithm.
