【摘要】：产品更新迭代加速对产品上市时间提出了更高的要求,产品设计项目工期对产品上市时间有重要影响。合理有效的设计项目进度规划是企业按时完成产品研发的前提。采取并行设计方式进行产品研发以缩短工期。并行设计过程中信息不确定性和返工迭代两方面特点加大了进度规划的难度。本研究基于DSM对产品设计项目进度规划进行研究。首先确定产品设计活动持续时间,利用高斯消去算法对其排序。在对活动之间信息互动方式和信息传递时间进行数学分析的基础上,引入迭代率,利用DSM构建项目工期数学模型。其次,为了确定活动时间因子,在对产品设计项目系统分析的基础上,结合DSM工期数学模型构建系统动力学模型,并通过参数设置进行模拟仿真。根据仿真结果,找出对项目工期影响最大的活动时间因子,确定期望工期。最后,本研究结合案例进行分析,通过与传统项目进度规划方法比较,证明本研究进度规划方法的合理性与可行性。产品设计工时的确立方法是本文的一个特色。在进度规划模型构建过程中,创新性地引入迭代学习率,并结合系统动力学相关知识,构建系统动力学模型进行仿真,为进度控制提供依据,保证工期的合理性。
[Abstract]:The acceleration of product update iteration puts forward higher requirements on the time to market, and the duration of product design project has an important effect on the time of product launch.Reasonable and effective design project schedule is the prerequisite for enterprises to complete product development on time.Concurrent design is used to develop the product to shorten the duration of the project.In the process of concurrent design, information uncertainty and rework iteration increase the difficulty of schedule planning.This study is based on DSM to study the schedule planning of product design projects.First, the duration of product design activity is determined, and Gao Si elimination algorithm is used to sort it.Based on the mathematical analysis of information interaction and information transfer time among activities, the iterative rate is introduced, and the mathematical model of project duration is constructed by using DSM.Secondly, in order to determine the activity time factor, based on the system analysis of the product design project, the dynamic model of the system is constructed by combining the mathematical model of DSM duration, and the simulation is carried out by setting the parameters.According to the simulation results, the activity time factor which has the greatest influence on the project duration is found out, and the expected duration is determined.Finally, this research combines the case analysis, through the comparison with the traditional project schedule planning method, proves the rationality and the feasibility of this research progress planning method.The method of establishing product design time is a characteristic of this paper.In the process of constructing the schedule planning model, the iterative learning rate is innovatively introduced, and the system dynamics model is simulated by combining the relevant knowledge of system dynamics, which provides the basis for schedule control and ensures the rationality of the time limit.
