提出了一种基于模糊数增长曲线模型的设计过程规划新方法。由于一个产品是由许多相互依赖的子系统组成的，因此一个工程设计过程由两种不同的知识创造活动组成，即一种是提高各子系统技术性能水平的活动，称为任务，另一种是提高子系统间完整性水平的活动。本研究以成长曲线来模拟技术性能与完整性的成长。一个数字的设计结构矩阵被用来表示任务的依赖性和协作效率。一个设计过程计划是通过技术性能达到设计目标的目标水平的概率来评价的。所提出的方法便于项目经理探索各种过程计划，评估其风险，并决定更好的计划。一个学生方程式赛车设计项目的规划实例表明，项目经理可以定量地比较各种工艺方案，并选择更好的方案。该结果表明，该模型朝着工艺规划的优化的可能性。
This article proposes a new method of design process planning based on a growth curve model with a fuzzy number managing uncertain design progress. Because a product consists of many interdependent subsystems, an engineering design process consists of two different knowledge creation activities, that is, an activity to enhance the technical performance level of each subsystem, which is called task, and an activity to enhance the integrity level among the subsystems. This research models the progress of the technical performance and the integrity with the growth curve. A numerical design structure matrix is used to represent task dependency and collaboration efficiency. A design process plan is evaluated by the probability that the technical performance will achieve the target level of design target. A proposed method facilitates a project manager to explore various process plans, to assess their risks, and to decide better plans. A planning example of a student formula car design project demonstrates that a project manager can quantitatively compare alternative process plans and choose the better plan. That result shows the possibility of the proposed model toward an optimization of process planning.
