Decision Support Technologies for Logistics Readiness Center

Qualtech Systems, Inc. (QSI) proposes to develop a comprehensive software environment for evaluating space system designs for mission reliability, supportability, and diagnostics (Integrated Health Management) performance. In addition to providing the capabilities to identify single points of failure and to estimate the probability of system failure as a function of the age of the system's components, the software tool set will enable system engineers to model complex and evolving system designs, trace design decisions, assess the system/mission reliability and availability, and perform a suite of analyses in support of performance enhancement. Specifically, the objectives of the software environment are to: (1) identify and model potential failure modes of a space system, (2) estimate the system reliability and the impact of the failure rates of the single point failures have on the overall reliability of the space system, (3) evaluate the mission reliability taking into account the interactions among different systems, and (4) incorporate system reliability in maintenance scheduling decisions. While Phase I will address algorithmic requirements and feasibility, Phase II will focus on tool development and integration needs with the Air Force Space Command's Virtual Space Logistics Readiness Center.
