| 摘 要： | 提出一种扩展的顺序迭代过程分析模型，包含的返工影响因子参数考虑了迭代对单个任务返工量的影响以及对任务剩余时间的影响。将描述复杂过程的设计结构矩阵改进为一种扩展的设计结构矩阵，使其能够表示该扩展模型。在模型参数为确定值的条件下，给出过程完工时间的解析计算方法，以软件开发过程为例给出试验计算结果。

| Abstract: | An extended analytic model of sequential iterative processes is proposed. The rework impact factors included in this model take into account the impact of iteration on the task duration and the remaining time of the task at the same time. An Extended form of Design Structure Matrix(EDSM) is introduced. The EDSM can describe the model. An analytic method for calculating the expected duration of the extended sequential iterative process is presented on the condition of assuming that the model parameters are deterministic. This method is illustrated by an application involving the calculation of the expected duration of software development processes. |
