Medlem Teknisk Kommittee: DAMRC (Danish Advanced Manufacturing Research Center), AMRC/Boeing Beskikket til Kvalifikationsnævnet En af seneste publikationer: The art of holding hand (Sygeplejevidenskabelig journal) Mentor: Grønlandsk Pædagog studerende Indehaver Danmarks førende guldspinderi Uddannelsesudvalg: UCN (Industri, laborant, etc) Bestyrelsen Idalederforum Nord Formand Sundhedsteknologi- Nord IDA Censor Maskinmester, Frederikshavn Syddansk, Odense - DTU

8 Udfordringer: Tab af competencer grundet manglende fokus og udvikling af uddannelser Erhversuddannelser: Praktikcentre på universitet Produktionsing: Basic træning på teknisk skole Eliteerhvervsuddannelser i et samspil mellem tek og uni Forsømt at opretholde kompetenceniveau i specialiserede industrier

9 Udfordringer Strategiske satsninger med fejl fokus Må ikke være konkurrenceforvridende Ligner ofte tilskud til opretholdelse af virksomhed Alt for mange programmer bliver djøf iserede Negative spiral på universiteter skal stoppes Morten Østergaard Har Tayloriseret universiteterne (som sygeplejersker, gymnasier, folkeskoler, etc) 20 års jubilæum for taksameter systemet Et universitet burde være kulturudviklende og bevarende Et universitet burde ikke være en forretningsenhed Medfører øjensynligt at de unge vælger dårlige uddannelser

10 Udfordringer Stramme rammevilkår Eksempelvis bræmme problematikken Energibeskatning For mange love provenu drevne For mange unge skal have en ungdomsuddannelse? 2 i matematik og dansk? Har vi de forkerte uddannelsestilbud? New public management Måling af performance Demotiverende system ildsjælene forsvinder Der bliver publiceret mere end der bliver læst Forkerte KPI afføder uønsket performance

11 Globalisering Vel ikke en ny udfordring Mærsk har altid været global Vikingerne var også rimeligt ude omkring Problemet er vel mere evne og vilje til at tilpasse lokale forhold til globale konditioner Søger til Kina for at få volumen, interesse og midler Virksomheder lægger ud ganske enkelt udfra profit hensyn (løn, rammevilkår) Tiltrækning af udenlandske arbejdere

21 Integrated Product and Process Development

22 Frontloading the Development Process Vision: Complete development in a virtual environment Production tools are ordered based on simulation results First complete car is built from production tools and in production facilities Final verification is done in physical cars Common data available for everyone

23 Udviklingen på software - hardware området: Et idag simpelt eksempel på plastisk deformation (300 knuder) I 1970 erene: 30 CPU-timer på datidens kraftigste computer Pris: 3* en adjunkts årsløn Idag: Få minutter på en arbejdsstation Pris: negligibel MPP-maskiner (Volvo eksempel ): Model med 1.1 mill elementer 77 CPU timer med maskine med 1 CPU 13.5 CPU timer med maskine med 42 CPU ere

24 Numisheet 93 benchmark test Nissan front fender Volvo: 1995: 40 timer på Volvo s kraftigste computer 2000: 15 minutter I dag:? Nu er det ikke bare interessant - men realistisk at foretage virtual protoyping incl. virtual processing

25 PRODUKTFREMTAGNING Hurtigt og korrekt første gang!!!! 80% af et produkts kvalitet fastlægges i designfasen 70% af de totale omkostninger fastlægges i designfasen mindre end 10% af de totale omkostninger bruges på design seks måneders forsinkelse kan medføre en reduktion i den mulige indtjening på mere end 30% hvis produktionsomkostningerne er 10% for høje reduceres den mulige indtjening med 20 % en forøgelse af udviklingsomkostninger på 50% vil medføre at den mulige indtjening reduceres med 3.5% Jo senere ændringer jo dyrere

26 FREMTIDIGE VILKÅR FOR KOMPONENT LEVERANDØRER Produktkvaliteten skal verificeres gennem brug af virtual prototyping Kvalitet og reproducerbarhed af fremstillingsproces skal verificeres gennem virtual processing

77 Summary on the flexible bellows The scheme was tested on 5 different setups The bell shape holds for each of the setups Robust and stable convergence was achieved The bell shape was identified through minimization of multiple objectives Problems defined by multiple objectives benefit from the nonmonotonical minimization scheme (helps avoiding dead lock) The flexible tubes represent an industrial part The optimized bellow has been test produced significant scrap reduction and significant component quality improvement Good coherence between simulations and experiments was achieved (flexibility and process stability)

78 Concluding remarks on the optimization scheme There are many tricks in this area: non-monotonic reduction, parameter scaling, bounds on the parameters, etc. Experience: Indicate a large usefull area with almost optimal products Most known process layouts were developed before the era of numerical controlled machines, thus candidates for an optimization schemes Optimization schemes can foster new and innovative solutions!
