According to the mission of this model, the statistical population is 250 documentary data available in the city of Mashhad, which have been collected by various centers such as welfare and police.

The results show that social security is objectively manifested with five general axes and twenty-seven components with different and different coefficients of importance. Interpretation of data by Shannon entropy method, which is the coefficient of importance in the research, respectively dimensions (creating a home zone) with a coefficient of 206%, (monitoring public places and service categories) with a coefficient of 212%, (improving disciplinary methods and changing reaction norms) With a coefficient of 201%, (change in the structure of the police) with a coefficient of 196% and (accountability of institutions by the police) with a coefficient of 193%.
