Abstract
The purpose of this research is to analyze structure of accidents generation in organizations based on the system methodology. It should contribute to a preventive approach at the project management stage of the future. First of all we point out necessity of an interdisciplinary risk management research over various areas of the safety problem. We in particular deal with "Organizational Accidents" in this research. To prevent the accidents, it is indispensable to recognize and understand potential danger which exists locally at the stage of "Concept making" and "Predetermined the definition" of the project. It is shown that the diagnosis for accidents prevention is necessary in system design phase. We insist that it should be effective to model the organization accident based on the idea of poly-agent system. Finally, we validate the models by using the case studies.
