System Design and Optimization
System design and optimization includes:
- Identification of system functions and requirements, components and integration
- Science and technology roadmapping
- Deployment
- Post-Deployment analyses.
Complex systems typically have diverse sets of requirements. Yet clear definition of system functions and requirements is essential if the system that is developed is to function as intended and meet user needs. ESG staff conduct system requirements assessments to ensure that all key system functions are identified, and to clarify gaps in existing system requirements. Clear linkages between system functions and requirements are created, and appropriate documentation of system functions and requirements are provided. Based on the system requirements, preferred and alternative technologies are then selected and integrated using a "roadmapping" process. The roadmapping process organizes technologies to meet system requirements within appropriate time frames, identifies technology needs and gaps, and facilitates trade-off analyses among alternative technologies. Following these analyses, the system can be deployed for further testing and evaluation. Depending on the specific situation, pre- and post-deployment performance analyses may be conducted to establish a performance baseline that can be used as a basis for maximizing system performance, minimizing costs, and/or minimizing risk and uncertainty. Key system performance factors include component interactions, operational ranges for the system and its components, and how each of the components affects overall system performance.
