Computer models simulating blast effects on ship personnel are needed, but thus far, development of modelshas focused on simulating blast effects on ship structure and equipment. Thus, capability gaps exist inpredicting the type and severity of injuries from surface or underwater weapon impact, estimating medicalresponse requirements, and determining outcomes of patients. The Human Injury&Treatment (HIT) modeladdresses these gaps. Algorithms are utilized for scoring the type and severity of injuries predicted, using avariety of existing and developing injury models. Additional algorithms determine the post-injury level ofincapacitation by evaluating how a physical impairment can impact performance of a task. A manningmodel simulates movement of personnel aboard the ship (Young, Allen,&Minks, 2011). It functionsiteratively with the Tactical Medical Logistics (TML+) code, a medical response model predicting resourceutilization and patient outcomes (Mitchell, 2004). Impact: HIT will help the Navy and commercial maritimeinterests anticipate medical response requirements resulting from blast attacks to a ship, andunderstand the impact of personnel loss on the crew's ability to perform damage control.
