This workshop session examined the role of sensing technologies and innovations in supply chain management in addressing these needs, while drawing lessons from industries such as aerospace, the automotive industry, and e-commerce. Kingon introduced the first set of speakers, Brant Simmons of General Electric (GE)

To anticipate maintenance needs, Simmons described how using digital twins to predict engine part replacement times can not only dramatically improve per formance, availability, and customer satisfaction, but also reduce engine failure and wasted time and expense by identifying whether an engine will accumulate damage quickly or can stay in service. Digital twins can also be used for routine in-flight monitoring.

Key challenges to creating autonomous ground combat vehicles include re ducing data latency, integrating multiple threat detection systems, understanding space and crew size constraints, working in extreme temperatures, and handling attacks or systems failures. In addition, Rogers said that testing and maintaining

Discussion Asked how these lessons may apply to optionally manned combat vehicles, ogers noted that teleoperated robotic systems primarily sense information and R have limited weapons capabilities. Some tank turrets can be remotely operated, freeing up design space and crew tasks, although more data functionality and band width will be required for the seamless onboard computing and communication capabilities desired for next-generation combat vehicles.

In response to another question, Gravitz said that DLA conducts quality con trol tests and is looking into digital twins to speed up the process. In order to circumvent cumbersome rules for commercial software, he said the organization performs data sensitivity checks in multiple cloud environments to minimize security risks.

To build the pulse center, Flex first carefully defined what data to collect, conducted proper data governance, created a trusted data repository, and then used trusted application programming interfaces (APIs) to create the visuali zations.

While technological tools can help, he added that workforce measures and employee training, especially with increased remote work, are also critical. FLEXIBLE HYBRID ELECTRONICS: OPPORTUNITIES IN SENSING, MONITORING, AND COMMUNICATIONS Nancy Stoffel, GE Research Stoffel discussed military and manufacturing applications of flexible hybrid electronics (FHE)

Maloney discussed research into environmental degradation of jet engine components and how the establishment of viable digital twins could help prevent catastrophic engine failure, emergency inspections, and the unnecessary retirement of planes from service.4 Engine ingestion of corrosive gases and fine particulate matter can result in sulfate-induced hot corrosion and deposit induced distress, necessitating the 4 P Wolfsteller, 2021, NTSB Says United Engine Failure Caused by Metal Fatigue, Flight Global News, February 22, https://www.flightglobal.com/safety/ntsb-says-united-engine-failure-caused-by metal-fatigue/142556.article.

That data can then be used to create physics-based life models to determine precisely when an engine needs to be serviced. To further improve the use of digital twins, Maloney said that research on key gaps, especially sensor technology for real-time data of the asset and its operating environment and the creation of physics-based life models, is under way.13 5 S.

SUPPLY RELIABILITY ANALYTICS Walter Yund, GE Variability in third-party suppliers' lead times creates a significant area of mis trust for global supply chain managers, especially if the provider is offshore or the part requires bespoke engineering. Yund described how GE is creating a program to go beyond asset and inventory visibility and into predictive analytics of inbound lead time in order to improve lead time variability, assembly time, customer satis faction, and overall supply chain reliability.

In general, hybrid electronics will not meet high-density interconnects enabled by wafer-level processing, Forsythe noted. GENERAL DISCUSSION The participants discussed opportunities afforded by digital twins and other tools, possibilities for expansion and reshoring of advanced manufacturing, and workforce needs in this space.

From page 33... ...
These next steps will potentially use digital twins and design software to facilitate domestic manufacturing. The domestic manufacturing, robust reliability testing, and digital twin design software will accelerate reshoring electronic assembly and packaging manufacturing using hybrid processes.

Handfield asked specifically about reshoring more advanced semiconductor manufacturing, and Forsythe answered that while it would be a lengthy process, Manufacturing USA Institutes like NextFlex can help to establish a fully domestic supply chain. Handfield responded that reshoring critical technologies would improve supply chain diversification, but suggested that it may take a variety of incentives to induce Asian-owned businesses to relocate.
