Abstract : The question of where to best invest limited research and development funds is a major concern. In missile defense the problem is exacerbated by the diversity of technologies that may be employed. Frequently, subjective methods such as the Delphi method and various weighting schemes are employed to rank choices. This paper introduces an objective methodology that avoids the problems encountered in subjective weighting schemes. It utilizes a System Performance Index (SPI) based on the physics of the problem as a unifying measure for assessing and ranking diverse technologies. The SPI is coupled with five other measures resources, cost, return on investment, technology readiness level, and time of insertion to completely characterize the technology with respect to a baseline. The SPI is calculated as the summation of the product of the Probability of Zero Leakage and the Value of the target area over the entire defended region. The methodology utilizes an abstract system model that embodies the physics of the problem and operates with Critical Performance Parameters that can be derived for the technologies using well-established analytical models and processes. Available tools for implementing the methodology and shortcomings are discussed, and the methodology is demonstrated through and example.
