Investigation of Dynamic Effective Factors on the Number of Insured Persons by System Dynamics Approach (Case Study: Social Security Insurance)

This paper presents a dynamic model to determine the effective factors which are responsible for making changes to the number of insured persons in health insurance companies and to study different policies for improving the system behavior toward its desired goals. For this purpose, all components of an insurance company including investment units, payment of medical expenses units, units which are related to the advertisement policies of the company and all other components that together will result in a complete collection of the company have been studied. According to the feedback relationships between these variables and the complexity of the issues, we use system dynamics approach for modeling and analyzing the effect of different policies. Given the goal of achieving the detailed results, Iranian Social Security Insurance is used as a case study. By taking into consideration this organization data from 2001 to 2011 in the proposed model, the results show that some parameters such as changes in investment policies and advertisement are effective factors, as far as the attraction of insurance company for people is concerned.
