This proposal addresses the need to develop a model of the avionics industry design process for selected government personnel to use in support of unified life cycle engineering (ulce) initiatives. Influencing the design process to account for all supportability, producability, performance, and cost considerations is the most highly leveraged life cycle cost opportunity in the life cycle of a weapons system, and is the overall focus of ulce. Users need a way of determining likely benefits OR costs resulting from proposed improvements and modifications to design of avionics for the air force. The proposal is to investigate alternate approaches to modeling the DOD avionics design process using various resolution discrete event deterministic vs. Stochastic models. Avionics design is the target for the pilot program, but the results are likely to be extensible to other design fields.
