| 摘 要： | 针对产品开发过程中存在的耦合迭代情况,建立了动态环境下基于混合迭代的耦合集求解模型。该模型考虑了任务执行工期的不确定性、任务输出分支的不确定性和资源分配的不确定性对项目完成时间和开发成本的影响,通过引入一个资源分配矩阵K,采用任务返工概率矩阵和任务返工量矩阵确定任务的执行状态和返工工作量。最后,通过实例仿真计算项目的时间和成本的分布。计算结果表明,资源不确定性对耦合集执行时间和开发成本有很大的影响,对资源进行重新分配有利于减少任务执行时间,降低开发成本。

| Abstract: | Aiming at coupling iteration existing in product development process,the coupled sets solving model based on hybrid iteration under dynamic environment was established. In this model,the effects of uncertain tasks' durations,output embranchments and resource allocation on duration and project cost were considered. At the same time,task rework probability matrix and task rework workload matrix under a resource allocation matrix K were used to determine the execution status of tasks and rework workloads.
