Public spaces are one of the most important elements of the city, where various cultural, social, and economic activities take place. These spaces create a lively city due to the creation of social interactions. The present study aims to know the influence of physical factors on social interactions. The study area includes the neighborhoods located in the old texture of Kashan city. The research is descriptive-analytical and a field survey was used to do it. The statistical population includes 51,576 residents of Kashan old texture and 200 sample were selected using Sample Power with a confidence level of 95% and a possible error of 5%. At the same time, using previous studies, a questionnaire with a five-point Likert scale was designed. Cronbach's alpha coefficient was used to measure the validity and reliability of the questionnaire. Classification and analysis of findings was done using SPSS software. Modeling has also been done using AMOS software. Based on the obtained results, there is no correlation between physical factors and social interactions in the Pearson correlation test, because in the old neighborhoods of Kashan, no attention has been paid to the collective and public spaces appropriate to the physical structure. The results obtained from the application of structural equations also indicate that social security and comfort variables have the highest factor loadings of 97% and 89%, respectively. This shows that with the increase of security, the comfort of residents also increases, that is, security affects comfort.

Due to the increasing health care organizations costs, their requirement to increase the quality, and also the complexity of their systems, the issue of the change and improvement to the systems has got really important. It was crucial to know which of methods and scenarios for the change of the systems, especially in the resources, lead to better conditions and this topic caused major issues. In this regard, discrete – event simulation as one of the decision making tools in operations research based on random data, has significantly helped policy makers and a managers. In this study, firstly, the key performance measures of Ghaem hospital emergency system using past publications and experts’ suggestions were identified. Then this system was modeled and simulated using Arena software. After weighting the criteria by AHP method, the scenarios of the experts were defined.  Finally they were ranked using PROMETHEE method and the most suitable scenario was determined.
