The Research and Development of the Time-Space Simulation of AIDS Transmission and Assistant Decision Support System in Kunming

China found the first case of AIDS in 1985. Since then, China faces an inefficient controlling and critical situation which is just like other developing countries at past 20years. It can be seen easily from present situation of AIDS transmission that the key of AIDS epidemic prevention and control is on prevention and control of AIDS transmission speed and range. That means that AIDS should implement the "prevention is better than cure" strategy. With information technology in-depth applications in prevention and control of AIDS transmission, information technology provides a new technical mode for prevent and control of AIDS transmission. This paper developed a time-space simulation of AIDS transmission and Assistant Decision Support System which based on the technology of Agent-based modeling (ABM) and Geographic information system (GIS) and took Kunming for example. OBJECTVIES: (1) Constructing AIDS agent model which will simulate the propagation of AIDS, (2) Implementing the functions of spatial analysis, spatial query, spatial statistics, dynamics spatially trend analysis of AIDS transmission, making and administrating of AIDS preparedness, monitoring and early warning analysis of AIDS epidemic, decision support spread of AIDS epidemic in a GIS environment. (3) Helping decision-makers decide on the best strategy to mitigate the spread of infection. Simulation software will help government departments and relevant managers to improve the effectiveness and efficiency of AIDS epidemic prevention.
