The Advanced Joint Effectiveness Model, or AJEM, is a survivability, lethality, and vulnerability (SLV) computer simulation code capable of analyzing one or more threats attacking one or more rotary-wing or fixed-wing aircraft, small watercraft, ground-mobile system, and mounted or dismounted personnel. It combines elements of target modeling, threat modeling, encounter kinematics, generation of weapon burst points, propagation of damage mechanisms to the target, damage mechanism/target interaction (penetration, fire, blast, behind-armor-debris (BAD), etc.), target system relationships (functionality, redundancies, etc.), and target remaining capability or loss of function.
AJEM produces results that are applicable during all phases of weapon system acquisition, from research, design, and development to production test and evaluation. The results are relevant to both acquisition decision makers and soldiers in the field.
AJEM is designed to run in conjunction with BRL-CAD, MUVES, and MUVES Tool Kit (MTK) environment, capitalizing on work already performed by ARL/SLAD.
