Model integration is one of the most important and widely researched areas in model management of Decision Support Systems (DSS). In disaster management area, independent DSS models handle specific decision-making needs, but it is possible that the need for combination of these models will be required. Therefore, the need for model integration and selection of such models arises. This paper presents the idea of decision support model integration based on software agents in an interactive disaster management domain. In this environment an automated model agent communicates with the other decision support system models and presents the hybrid decision support system model as a solution. This system starts with minimal information about the user's preferences, and preferences are elicited and inferred incrementally by analyzing the needs and requirements of the user.
