Joint Theater Level Simulation - JTLS

U.S. Readiness Command, the U.S. Army War College, and the U.S. Army Concepts Analysis Agency, Jet Propulsion Laboratory

The Joint Theater Level Simulation (JTLS) system is an interactive, multi-sided (10) model used to simulate joint and coalition forces operating simultaneously in the air, land, and water environments. The JTLS Executive Overview provides a general description of JTLS's programmatic history, standard hardware, software, and functional capabilities.

The JTLS system consists of six major software programs and numerous smaller support modules that interoperate to prepare scenarios, execute model processes, and analyze the results. The model is theater-independent and does not require programming knowledge to effectively execute. JTLS was originally conceives as a tool for the development and analysis of operation plans (OPLANs) but has excelled as a CAX support tool, senior staff training facilitator and support system analysis capability. The JTLS system operates on a single computer or on multiple computers, either at single or at multiple distributed sites. It is reconfigurable on the fly. Its web based capability allows users to access JTLS from anywhere they can access the Internet.

Model features include Lanchester attrition algorithms for certain ground combat operations, and detailed modeling of logistics, air, ground and naval forces. The forces can be either military or civilian or a mixture. The JTLS system includes software designed to aid in scenario (database) preparation and verification; entering game orders; and obtaining situational information from graphical displays, messages, and status boards. It has been used for OPLAN analysis and scenarios dealing with homeland defense scenarios, smuggling, terrorism and natural disasters.
