The present study has been made with the aim of damage identification of storekeeping system of common logistics items in a defense industrial unit based on trifurcation pattern. Therefore, it is considered applied in terms of conclusion, descriptive in terms of aim and sectional in terms of time. After studying the history of issues and reviewing available patterns and formation of theoretical framework, important variables of the research were identified and the conceptual model and research hopotheses were recognized. To measure the variables, a researcher-made questionnaire has been used that the validity of its contents has been approved by intelligentsia and its Cronbach's alpha coefficient has been measured to evaluate its reliability. The case study in this research consists of 127 logistics personnel of industrial defense unit chosen by random sampling method. The result of research hypotheses, with the help of single-dimensional T-test and Fridman, shows the convenience of structural factors situation and inconvenience of contextual and behavioral factors situation.

The most important damage of contextual factors consist of institutional culture, status, and credit, past turnover and the most important damage of behavioral structure are management and leadership, information system, absorption, sociability, education, protection and conservation, performance evaluation, exerting and investigating complaints.
