The organizational management system of unsafe behavior is generally difficult to operate stably for a long time. This paper proposes a control model of organizational management for unsafe behavior, based on the full consideration of the relationship between management variables. Due to the existing influence relationship between variables, the deficiency of the to be improved variables and their antecedents should be identified as the vulnerability in organizational management, the importance of the variable itself and the influence intensity between variables should be taken into account. Armed with this research idea, first of all, the scope, the variables, the construction steps and the operation process of the control model are determined by combining the behavior safety “2-4” model and the feedback control theory. Then combining triangular fuzzy number with the weighted influence non-linear gauge system(WINGS) algorithm while considering the uncertainty of subjective judgment, the influence relationship between variables is described, and the integration of their own importance and the influence strength between variables is realized. Moreover, the paper gives the method of identifying management vulnerabilities and determining control measures. The case study shows that the control model is helpful to improve the capacity of identifying the vulnerability in organizational management and the rationality of sequencing the control measures.
