Explanation of Formation and Transformation Process of Space Security in informal settlements

the main question of this study is what are the indicators and criterions affecting spatial security and what and how is the process of formation and development of spatial security in informal settlements. The method of the present research is descriptive-analytical and the methodological approach is based on a mixed-method (quantitative and qualitative). We conducted this research in this way: In the first section of this research, by examining the theoretical literature, library and Internet resources such as scientific databases, specialized journals related to the field of security and informal housing, and research projects conducted by related organizations, we were able to identify and survey the effective criterions and indicators that are influential to the formation of spatial security (location based security). Then; in order to make a connection and sequence between dimensions and indicators, the structural model was presented and the stages of formation were explained using the interpretive structural equations approach. The results of the integrated spatial security model were classified and graded into four main levels, in which the principles of urban design and environmental design identified as the most influential factors. In the next section, according to the results of the interpretive model and the opinion of experts, the process of formation and transformation of spatial security in informal settlements was identified in four stages, respectively; The primary maturity of security (producing security), the secondary maturity of security (monitoring and protection of security), the security of occupation and finally the stage of complete maturity of security.
