【摘要】 针对系统的总体结构分析,首先分析了国内文献中介绍的ISM(解释结构模型)方法的一种简便方法所存在的问题,明确指出该简便方法由于只以"1"的个数多少来重排缩减矩阵M′的行和列的次序,致使得出的多级递阶结构模型中,有可能会出现要素间的错层现象,并举例给予说明,然后提出一种与原ISM方法等效的简便方法(ISM—阵上作业法),并严格证明了它的正确性。更多还原

【Abstract】 Concerning analysis of system integral structure, a simple and convenient method of ISM(Interpretative Structural Modeling)introduced by some domestic references is briefly described at first. Then,the weakness of the method is analyzed and illustrated. It is definitely indicated that the order of row and column of the reduced matrix "M′" is newly arranged only according to the amount of "1" with the result that elements probably appear at wrong layers in the obtained hierarchy model. Mainly,the improved method(the ISM method working on matrix)equivalent to the original ISM method is presented. The correctness of the method is strictly proved in the end.更多还原
