Subject:* "Life-cycle Simulation"
A life-cycle simulation capability has been developed around systems engineering principles to analyze the risk of the development of complex systems. The systems engineering process begins with understanding and refining stakeholder requirements and flowing down the requirements from the systems level to the technology level. System functions are developed to meet requirements and physical architecture options are analyzed in an operational environment to determine if functions and requirements are met. A simulation was developed to analyze the performance of the system to meet mission and operational requirements though the life cycle from concept through operations. Qualitative approaches are used to determine probability of cost, schedule, and performance success. By integrating simulated performance impacts with qualitative analyses ofprogram/project cost and schedule, a risk matrix is developed for program management decisions. In addition to risk management, this life-cycle simulation has been used for investment versus life-cycle cost trades, requirements flowdown, and cost as an independent variable analyses.
One of the applications for this tool is NASA’s Next Generation Launch Technology Program where performance and technology risk is traded to meet NASA’s future goals.
