一种改进的多属性系统结构分析模型

Improved Multi-attribute System Structural Analysis Model

为减少系统结构分析中的主观因素影响及模型计算量,提出一种改进的多属性系统结构分析模型。采用由要素到属性的分析思路,区分要素/属性的类别。通过影响度"合成"和贡献度"分解"计算要素/属性的影响程度。对通信网络系统结构的实例分析表明,该模型能够定量、合理地给出各网系/指标的贡献度和关联度,具有一定的客观性和可行性。

To reduce the subjective interfere and computation complexity in system structural analysis, an im-proved multi-attribute system structural analysis model was proposed. With the analysis from elements to attributes, the influencing degree of different kinds of elements or attributes was calculated by combining of influencing degree and decomposition of contribution degree. Structural analysis on communication networks system shows that the pro-posed model can present contribution degree and relation degree of networks or indexes quantificationally, indica-ting the rationality and feasibility of the model.
