Folkertsma, CEng Production, use & retirement Autumn 2024 4 / 23 Manufacturing Who and how many? dr. ir. G.A. Folkertsma, CEng Production, use & retirement Autumn 2024 5 / 23 Manufacturing Scope Many / series production Few / “one-off” I Supply chain I Subsystem verification I Incoming goods inspection I FCA / PCA I Work instructions I “As-built TPD” I QA inspections I Outgoing logistics dr. ir. G.A. Folkertsma, CEng Production, use & retirement Autumn 2024 6 / 23 Manufacturing Integration checks: FCA and PCA 1. The (sub)system does not build/cannot be made/ does not fit. I Executed on CIs 2. The (sub)system does not function. 3. Interface errors. I FCA: does it work? 4. The (sub)system is too slow. I PCA: was it built according to design? 5. The (sub)system does not meet main performance parameters. 6. Reliability is not met. dr. ir. G.A. Folkertsma, CEng Production, use & retirement Autumn 2024 7 / 23 Manufacturing Integration checks: TRR I Internal I TEMP (MTP) check I Test plans (TAS) I (Intermediate) Test results (TAR) I Supporting documentation I Support, test equipment, and facilities dr. ir.

Folkertsma, CEng Production, use & retirement Autumn 2024 9 / 23 Manufacturing Exercise: FAT and SAT for robot digger For your robot digger: a) Describe what the Factory Acceptance Test (FAT) looks like. b) Describe what the Site Acceptance Test (SAT) looks like. Remember your key customer needs, key drivers, scenarios and mission, and relate the FAT+SAT to those. After 15 min, I will ask for some examples. dr. ir. G.A.

G.A. Folkertsma, CEng Production, use & retirement Autumn 2024 17 / 23 Circularity “ If it can’t be reduced, reused, repaired, rebuilt, refurbished, refinished, resold, recycled or composted, then it should be restricted, redesigned or removed from production. ” – Pete Seeger, AT 89 tr. 15 dr. ir. G.A. Folkertsma, CEng Production, use & retirement Autumn 2024 18 / 23 Circularity out of our wasted products. (Urban Mining) Where the old economy is characterized by take make use and dispose, the upcoming circular economy aims to use and Closing the loop keep resources at the highest possible purpose. use of finite Damage to resources NOW the (future) from the past planet Take Make Use Dispose Share Unrecoverable Repair Use Losses Re-Use Refurbish Re-Use on part/module level Re-Use on material / chemical level / Re -cycling Downcycle loss Regenerate Lifecycle Losses life cycle consumption (e.g. energy, water) dr. ir.

With viewport, it is Circularity latterly meant to view with another focus and perspective and the viewport goals will help to do so. How? 0.

Folkertsma, CEng Production, use & retirement Autumn 2024 20 / 23 Circularity Exercise: circularity for robot digger 1. Come up with two or three footprint reduction ideas. Think about material, operation, energy, business model, retirement, … 2. Determine how to quantify† the impact of each. 3. Try to quantify the financial aspect of each. Consider the cost of development, goods, production, use. † Define a metric, even if you cannot give a number right now. After 10 min, I will ask for some examples. dr. ir. G.A.
