Obsolescence meldingen (ALSTOM product scope) PDN = Product Discontinuance Notice
− 15% van de obsolescence gevallen zijn kritisch (geen FFF vervanging) − Voornamelijk elektronische componenten Presentation title - 19/05/2014 – P 8 © ALSTOM 2013. All rights reserved.

Stappen in Obsolescence Management
• Zorg dat alle componenten beschikbaar zijn gedurende een gedefinieerde periode: − Lifetime contracten, RS life, keuze componenten
• Houd een helder zicht op de obsolescence status van het product − Systeem, product / apparatuur , component
• Minimaliseer de consequenties van obsolescence als het optreedt − Alternatief onderdeel, vervangend onderdeel, opslag, redesign, reparatie regime, bewaren van “scrap”
• Dit vraagt om samenwerking in de keten Presentation title - 19/05/2014 – P 9 © ALSTOM 2013. All rights reserved. Information contained in this document is indicative only.

Samenwerking in de keten Voorbeelden hoe het niet moet • Voorbeeld 1: Bestuurders display −Leverancier ontwikkelt vervanger in eigen beheer • Nieuwe hardware en nieuwe software − Betere leesbaarheid − Steviger front plaat (minder reparaties) − Modernere interface (USB vs PS/2) − Software weer onderhoudbaar
−Vervolgens blijkt klant een ander pad te bewandelen • Goedkopere reparaties (aanname)

Samenwerking in de keten Voorbeeld hoe het ook kan • Voorbeeld 2: IGBT −Een IGBT wordt gebruikt in meerdere complexe subsystemen bij verschillende klanten: • Redesign op alle subsystemen, alleen gebruikt bij reparatie. − Hoge kosten, hoge MTTR, risico’s
• Redesign op één subsysteem, oude onderdelen voor reparaties − Lagere kosten, lastiger logistiek, lagere MTBF na reparatie − Samenwerking tussen meer partijen

Discussie onderwerp
• Voor obsolescence is een goede samenwerking tussen leverancier en gebruiker noodzakelijk • Hoe kan samenwerking binnen de keten en kring van gebruikers gaan werken als de obsolescence onevenredige impact heeft −Is een bedrijf bereid kans op lagere MTBF te accepteren in ruil voor veel lagere redesign kosten
