OBJECTIVE: develop an electrical system digital twin (immediate circuit rendering) enabling dynamic electrical system navigation, inspection, documentation, and debug capabilities. DESCRIPTION: To meet the above objective, the project shall develop an online visualization and debugging solution which renders circuit schematics, wiring harnesses, and component attributes specific to individual development and maintenance situations. The technology here should be capable of taking original electronic computer aided design (ECAD) data, Excel tables, or proprietary data as input, then autonomously render and explore schematics, thereby allowing complex systems to be easily and quickly understood. The technology should allow for Google-style live search features allowing for precise information to be extracted from large data files and displayed in an easy-to-understand fashion. The technology developed here should allow for views to be modified and transformed as users operate the system, with important information displayed on the schematic in real time. The technology here should also highlight key data to accelerate development and debug capabilities. PHASE I: FEASABILITY DOCUMENTATION. For this Direct-to-Phase II topic, evaluators are expecting that the submittal firm demonstrate the ability to render online visualization and debugging platforms depicting or representing circuit schematics, wiring harnesses, and component attributes specific to electronic maintenance situations. Evaluators are expecting that the submittal firm demonstrate understanding of electronic maintenance environments and workloads. PHASE II: Develop technology for electrical system digital twin (immediate circuit rendering) generation enabling dynamic electrical system navigation, inspection, documentation, and debugging operation. Technology should be able to utilize existing technical order documentation to transform products into interactive versions at no cost to legacy data owners. Technology should allow for cloud based interface to be used without modification to existing technical data. Technology should provide for unique Google-style live “search and show” for easy debugging of electrical systems. PHASE III DUAL USE APPLICATIONS: If the Phase II is successful in developing the technology, transition technology wherever beneficial and of net present value into Air Force and other government electronic maintenance groups and related environments.
