Imagine a small team at JUFE preparing its 131st lecture series for public release. They strip the file down to a minimal, subtitle-only version to lower bandwidth, tag it ENGSUB02-02-03 to show it's the second language track, second encoding pass, third edit, and mark it FREE to invite students worldwide to download it. The filename becomes the public face of months of editing, meetings, and choices about accessibility and openness. JUFE-131 ENGSUB02-02-03 Min -FREE-

| Concept | Short Definition | Typical Use | |---------|------------------|-------------| | Engineering Substitution | The purposeful replacement of one element (material, component, process) with another to meet a set of design criteria. | Product redesign, cost reduction, compliance. | | Substitution Decision Matrix (SDM) | A tabular scoring system where each candidate alternative is rated against weighted criteria (cost, weight, durability, etc.). | Rapid comparative assessment. | | Embodied Energy (EE) | Total energy consumed in extracting, manufacturing, transporting, and installing a material. | Sustainability evaluation. | | Design for Substitution (DfS) | Design philosophy that anticipates future changes, making parts modular and replaceable. | Long‑term product lifecycle management. | | Risk Mitigation Strategies | Supplier diversification, accelerated life testing, contingency sourcing. | Reducing technical and supply‑chain exposure. | By the end of the mini‑lecture, learners will be able to:
