本文提出了一种使用高级仿真来管理复杂设计项目的过程建模和分析技术。该模型计算随机、资源受限的项目网络中交付时间的概率分布，其中迭代在顺序、并行和重叠任务之间进行。该模型使用设计结构矩阵表示来捕获任务之间的信息流。我们使用基于模拟的分析来解释设计过程行为的许多现实方面，这在以前的分析模型中是不可能的。我们针对迭代项目网络中的随机、资源受限的项目调度问题提出了一种启发式方法。该模型可通过识别流程改进的杠杆点来更好地进行项目规划和控制，并用于评估替代规划和执行策略。提供了一个工业示例来说明该模型的实用性。
This paper presents a process modeling and analysis technique for managing complex design projects using advanced simulation. The model computes the probability distribution of lead time in a stochastic, resource-constrained project network where iterations take place among sequential, parallel, and overlapped tasks. The model uses the design structure matrix representation to capture the information flows between tasks. We use a simulation-based analysis to account for many realistic aspects of design process behavior which were not possible in previous analytical models. We propose a heuristic for the stochastic, resource-constrained project scheduling problem in an iterative project network. The model can be used for better project planning and control by identifying leverage points for process improvements, and for evaluating alternative planning and execution strategies. An industrial example is provided to illustrate the utility of the model.
