This report is a summary of all significant studies performed by Raytheon Company during our participation in the JTCGAS TEAS program. The studies encompass primarily three areas Survivability assessment modeling, Mission cost-effectiveness methodology, and Survivability assessment studies. In the survivability assessment modeling area, several aircraft attrition models were evaluated to determine their applicability to the TEAS effort, and modeling deficiences were identified. In addition, attrition modeling requirements were outlined again with the TEAS objectives in mind to establish a more effective baseline model, and modeling validation techniques were studied to establish model credibility. A mission cost-effectiveness methodology is described to assist the Survivability Assessment Subgroup in the evaluation of the baseline aircraft. Following the definition of a generalized mission effectivenesssurvivability model, a cost model based on the WESIAC method was outlined and a sample problem was described to demonstrate a typical application to the TEAS program. Finally, survivability assessment studies were performed to provide examples of how current survivability methodologies could be applied to the study of aircraft attrition.
