基于分级SDG的物资供应方案缺陷分析建模研究

Modeling Research on Defect Analysis of Material Supply Project Based on Grade SDG

针对物资供应方案缺陷分析困难,引入定性建模的符号定向图(SDG)方法进行建模研究。对物资供应方案的概念、缺陷分析的重要性和存在的主要缺陷进行概括,简明论述选择SDG法研究的优势并介绍分级SDG,建立了物资供应方案的缺陷分析定性模型,在研究定性推理方式的基础上对所建模型进行定性推理,设计实例获得唯一推理结果,对推理结果进行分析。结果证实了用SDG定性建模的方法研究物资供应问题的可行性。

Aiming at the difficulty in analyzing Material Supply Project, Signed Directed Graph （SDG） method in Qualitative Simulation was introduced to modeling study. The concept, the importance of defect analysis and existing main defect of Material Supply Project were generalized; the advantage of choosing SDG was simply discussed and the grade SDG was introduced; the defect analysis Qualitative model of Material Supply Project was constructed; the model was qualitatively reasoned through studying Qualitative Reasoning methods, an example to reason was designed and the only reasoning result was obtained, the result was analyzed. The result shows that it is feasibility to study the problem of Material Supply Project usinsg SDG.
