“…Although fully deployed to condition new or refinished optics, AMP has yet to be added to the NIF ORL [24]. Researchers at the French Alternative Energies and Atomic Energy Commission (CEA) however have employed AMP processes within the Laser Megajoule (LMJ) optics recycle loop reporting improvements in damage threshold [4]. For this case study, we will consider adding an AMP process to the NIF ORL as a mature technology ready for implementation.…”

“…Researchers at CEA published LMJ optics recycle loop details that included an AMP process, suggesting optics performance benefits from this chemical treatment process [4]. Although the benefits of AMP processes are well-documented by NIF researchers, most of the published data only consider the AMP process to prepare new optics, but not as part of the recycle loop.…”

Production enterprises are continuously presented with investment opportunities to improve their production systems through the adoption of new technologies. When presented with these opportunities, enterprise leaders are faced with decisions that can have profound viability implications. A value-centric framework to holistically and systematically inform and support decisions is needed.This research introduces such a strategic framework based on Engineering Systems principles and methods. Within this framework, Enterprise System Architecting and Technology Roadmapping methods have been adapted for production systems to identify stakeholder value, create investment scenarios as project portfolios, assess performance using Discrete Event Simulation (DES) and technical modeling, and visualize options using tradespace plots.A case study, involving a representation of the National Ignition Facility's (NIF) Optics Recycle Loop production system, is explored to demonstrate the framework process steps as a guide for its application. Each of the process steps is applied to the optics production enterprise resulting in a recommended project portfolio spanning 20 years. The baseline DES simulation predicts a throughput of 129 optics/month. After investments into debottlenecking, this was boosted to 261 optics/month. In addition, product performance forecasting predicts that after product improvement investments, optics damage threshold -a key product performance figure of meritwill improve by 67%. By using the new strategic framework, production enterprises can make decisions based on projected present and future value.
