A distributed simulation system for team decisionmaking

This paper gives an overview of a unique distributed, real-time simulation system for studying team decision-making and coordination-the DDD (distributed, dynamic, decision-making) paradigm. The DDD paradigm captures the essential elements in real-world decision-making problems and integrates them into a controlled, computer-mediated, laboratory setting. The DDD simulation system is implemented on a network of UNIX workstations with real-time control, online data acquisition, interactive graphical display, and a simulated inter-human communication network. With a highly reconfigurable user interface and a flexible scenario generator, DDD has been used in many team decision-making experiments with different problem context, including military command and control, job scheduling, and medical diagnosis.<>
