CREATE?-AV DaVinci Strategic Airlift Pilot Project

摘要

Decisions made during early phases of systems design and acquisition often determine the majority of the life-cycle costs for those systems. Decision support systems driven by physics-based, proper fidelity models can improve the quality of early acquisition decisions. The DaVinci software product suite is being developed in direct response to these needs with a focus on conceptual system modeling of air vehicles. DaVinci is designed around a unified life-cycle engineering model encompassing multi-fidelity analysis for a wide range of applications. At its core, DaVinci provides next generation modeling capability for functional analysis, alternative design evaluation, trade-space exploration, decision making, and acquisition planning. The DaVinci infrastructure and architecture will enable a collaborative environment for all aspects of early acquisition processes and provide a much more effective mechanism for transferring detailed models and product descriptions between phases of acquisition throughout the life of the program. DaVinci couples a rich graphical user interface with pre-engineered system components and large scale computing to allow systems engineers and acquisition stakeholders the use of computationally based engineering to enable rapid system engineering development iterations for requirements traceability, sensitivity analysis and uncertainty propagation, physics-based systems representations, and the creation of multi-fidelity models suitable for early preliminary design. The current effort used the DaVinci tool in collaboration with several other tools to perform a study on configuration trade-offs for a strategic airlift concept.
