Abstract

Duringthelastfewyears,attentioninthemanufacturingcyclehasshiftedtowardsconcurrentengineering（CE）.Withthis,theintegrationofthedifferentproductlifecycleprocesseshasbecomeafocusinbothresearchandindustry.However,itisobviousthattheintegrationofallmanufacturingprocesses,takingintoaccountalllifecycleaspectsfrominitialfunctionalrequirementstofinaldisposal,ishardlyfeasibleinthetraditionalway.

1.Introduction

Intheresearchpresentedhere,itisadvocatedthatthesheerintegrationofmanufacturingprocesseswithintheproductlifecycleisinsuf®cienttoachievetrueintegratedproductdevelopment.Forthispurpose,themainfocusshouldbeontheinformationthatisappliedandgeneratedinthesemanufacturingprocesses.Iftheinformationoftheseparateprocessescanbemadeavailableduringtheentiredevelopmentcycle,itcanbethebasisforthecontroloftheentiremanufacturingcycle.Inordertotakefulladvantageofthemodi®edroleofinformationintheproductdevelopmentcycle,adifferentattitudewithrespecttothemanufacturingprocessesisrequired.

Oneofthemaindifferencesis,thatthephasesinthemanufacturingprocessbecomeinstrumentaltotheinformationrequiredinthemanufacturingprocess.Thisimmediatelyimpliesthatprocessesinthemanufacturingcyclehavetobedefinedasgenericasmuchaspossible.Forexample,itbecomespracticabletointerchangesystemsdevelopedfordifferentproducttypes（prismatic,sheetmetal,etc.）.Moreover,iftheinterfacesofthemutualsystemscanbedefinedadequately,thesesystemscanbecomeindependentmodules,thatareabletoperformtheirtaskswithoutbeingdependentonapredefined,sequentialscenario.A®rstprerequisiteforthisistheabilitytoeffectivelymanagetheinformationthatbecomesthebasisofthemanufacturingprocess.
