Abstract
A novel distributed computing software solution, Simple Real-Time Infrastructure (SRTI), is developed to model the interdependencies that arise in community resilience simulations. SRTI is based on a client-server structure and uses a publish-subscribe pattern to realize data communication between the distributed simulators for different fields. This approach provides a scalable, versatile, and user-friendly solution for integrating multiple discipline-specific models in hazards simulation. Each simulator is treated as a black box that interacts through the SRTI distributed computational platform. In this article, the SRTI is described comprehensively from the high-level structure to its fundamental components including the RTI Server, RTI Lib API, data structure, and the graphical user interface (GUI), as well as optional methods to utilize this framework and its components. Also, several ongoing important updates and improvements of the SRTI are introduced. Lastly, two example implementations that consist of a group of developed simulators for assessing the impacts of earthquakes on community resilience are presented.
