基于GERT网络模型的课程实际度量值研究

Research on the Measurement of the Curriculum Based on the GERT Network Model

运用系统论的思想和随机网络的基本理论，结合工科院校《概率论与数理统计》的课程结构和体系的特点，构建了该课程人才培养的GERT网络模型．利用信号流图中的梅森公式求解了该课程描述模型中的课程实际度量值，同时对课程完成寿命的周期问题和循环过程进行研究．结合模型参数的灵敏度分析，通过章节之间变化的相互关系获得该课程对人才培养的完成时间及相关的评价参数，并提出了培养应用创新型人才的课程研究决策建议．

The GERT network diagram of the course personnel training were constructed on the basis of the theory of the system and the basic theory of stochastic network, combined with the characteristics of the course structure and hierarchy of probability theory and mathe- matical statistics. By using the Mason formula in the signal flow graph, the actual value of the course in the course description model was solved. At the same time, the research on the cycle of life cycle and cycle process was carried out. Through the change of the relationship between the sections of the course, the paper solved the completion of the training of personnel and related evaluation parameters, combined with the sensitivity analysis of model parameters. At last, the paper put forward the suggestion on the course of training innovative talents.
