JOEF (Joint Operational Effects Federation) Architecture

JOEF (Joint Operational Effects Federation) is a simulation federation that supports CBRN (Chemical Biological Radiological and Nuclear) warfare on military operations. Its primary interface to users is JWARN (Joint Warning and Reporting Network), which is an automated reporting of CBRN incidents for the joint or each service. It also automates the transfer of data between CBRN detectors/sensors and C4I systems, and minimizes the effects of a hostile attack, accidents or incidents. Therefore, the fundamental role of JOEF is to provide the modeling and simulation analytical capability to determine and assess the impact of CBRN warfare on military operations. It specifically supports assessment of wartime operations and risk levels, assessment of wartime preparations for employment of CBRN defenses and resources, and advance planning and analysis to support assessment of CBRN operational alternatives in conjunction with JWARN in real-time mode. This paper describes the JOEF conceptual architecture for the structure of operational-effects models (i.e., transport and dispersion models). The architecture includes the specification of software module interfaces so that the modules become plug-and-play operational effect simulations. It also allows for direct interfaces to a web-based application and user interfaces. Finally, the architecture is compliant to DII-COE, which is the DOD C4I interface standard.
