COMPLEXITY OF THE ANALYSIS PROBLEM Speed and observability both affect the operational utility of air vehicles, but any analysis of their trade-offs is confounded by many other design and operational variables that interact with them and also affect the operational utility of the air vehicle. Some of these design variables are listed below and defined in the Glossary in Appendix D:1 1The reader is referred to Robert E

. Given the multidimensional nature of the problem, the analysis of speed-and-observability trade-offs on the bases of their contribution to the utility of air vehicles is a complex activity.

FUtURE AiR FoRCE nEEdS FoR SURViVABilitY Task 3: Develop Experimental Designs for Simulation Runs Conceptually, one would like to examine the effectiveness and survivability impacts for all combinations of air vehicle design variables over their feasible ranges (with consideration given to their engineering interactions) to identify designs that maximize effectiveness and survivability in important missions and operation situations.

These can be used as baselines to compare with runs involving simulated future air vehicles. Task 4: Set Up, Conduct, and Analyze Initial Simulation Runs Although many design variables impact on the survivability and effectiveness of potential air vehicles, a major focus is to identify a good balance between speed and observability capabilities for different levels of other design parameters, missions, and Ops Sits.
