摘　　要：针对要素数目繁多、关系结构复杂的系统中层次分析困难、处理效果差等问题,提出一种新的含可达影响因子的系统结构分析算法.该算法根据定性判断和综合试验分析确定综合影响矩阵,进而根据中心度、原因度等信息对不重要要素进行判别和处理,在此基础上通过修正影响矩阵实现对系统的等级划分,得到含有可达影响因子的系统结构分析模型。算例对比分析表明,该算法可以在合理忽略不重要要素影响关系的基础上实现区域分解和等级划分,既简化了利用改进型布尔代数法则计算可达影响矩阵的复杂性,又定量地给出主要要素之间的影响程度,具有很强的实用性.Aiming at the difficulty and complexity of system structure analysis,a new system structure analysis arithmetic with reachable effect factor is presented.The effect matrix is obtained based on qualitative estimation and experimentation analysis firstly,then the administrative levels of system structure is actualized based on emendatory effect matrix in which unimportant elements judged by center degree and cause degree are omitted.Finally system structure analysis model with reachable effect factor is established.Experimental results show that,the proposed arithmetic could realize the system structure analysis effectively based on the fact that unimportant elements and their effect relations are omitted,and its improvement and practicality lie in the fact that it not only reduces the complexity of computing reachable effect matrix by using improved Boolean algebra rules,but also presents the effect degree of important elements quantificationally.
