By he mid-eigh ies, he Ai bus A320 and he CASA CN235 we e designed using a Compu e Aided Design (CAD) ool, o he 3D su aces and d awings, and a Compu e Aided Manu ac u ing (CAM) applica ion, o nume ical con ol p og amming. In he mid-nine ies, P oduc Da a Managemen (PDM) sys ems and 3D solid modeling le Ai bus o s a building a p oduc Digi al Mock-Up (DMU), mainly o check unc ional design in e e ences. Then Concu en Enginee ing was in o- duced and a huge p ojec , named ACE (Ai bus Concu en Enginee ing) [ 3 ], s a ed o de elop and deploy me hods, p ocess and ools along all he unc ional design disciplines. A b ie summa y o he p oduc Digi al Mock Up (DMU) a Ai bus is p esen ed in [ 4 ]. The complexi y o an ai c a as a p oduc is no only a unc ional design le el. The complexi y is also ela ed o he indus ial design o he ai c a and he gene a ion o he manu ac u ing documen a ion. The li ecycle o a ypical ai c a could be mo e han 50 yea s.

Finally he pape ends wi h an in oduc ion o CALIPSOneo P ojec as a p oo o concep and some conclusions abou he wo k. 16.2 The Role o PLM o Cope wi h This Complexi y PLM me hods and ools a e a ge ed o manage p ocesses and enginee ing p ocess in he i s place. The e o e PLM is being in oduced in he ae onau ical indus y o manage p ocess complexi y wi hin unc ional and indus ial ai c a design. The in oduc ion o PLM me hods and ools a e pa o he e olu ion o he enginee ing p ocess al eady aking place in he ai c a indus y. This e olu ion is due mainly o he echnological e olu ion o so wa e ools, he need o sho ime- o-ma ke , o educe cos and o inc ease quali y and ma u i y o he de elopmen . PLM is also a main enable o his e olu ion. This e olu ion can be esumed in h ee enginee ing pa adigms: adi ional, concu en and collabo a i e. 16.3 T adi ional Enginee ing The T adi ional Enginee ing app oach o design a p oduc is he implemen a ion o design asks in sequence (Fig. 16.1 ). Main disad an ages o his app oach a e: only ocused on p oduc unc ionali y, suppo ed in d awings, di e en eams wi h lack o communica ion be ween hem o which is o en e e ed o as he “o e - he- wall” app oach [ 5 ], p oblems pushed down o he end o he li ecycle, and long ime- o-ma ke . 16.4 Enginee ing Abou 20 yea s ago, and wi h he in oduc ion o he eme gen PLM ools, a wide- company p ojec , ACE (Ai bus Concu en Enginee ing) [ 3 ] was launched. F amed wi hin he Ai bus A340-500/600 de elopmen p og am, i aimed o de elop and deploy concu en enginee ing p ac ices and he associa ed PLM ools. Concu en Enginee ing diminished he disad an ages o he adi ional pa adigm (Fig. 16.2 ). The wall desc ibed in T adi ional Enginee ing s ill exi s bu i is no so high. The indus ializa ion asks a e no as ad anced as unc ional asks in e ms o PLM ools usage. The cu en deli e able is again he p oduc DMU, in e ope abili y and wo king p ac ice issues cause ha compac disks o memo y s icks l ies o e Fig. 16.1 T adi ional iew s. concu en iew he wall ins ead o pape based d awings. Indus ial design is no ully in eg a ed wi h unc ional design, and i has li le in l uence o e he la e . They comp ise wo sepa a e eams wi h dissimila skills. In ac , one o he mos impo an easons o ha e he wall is he ce i i ca ion p ocess by he ae onau ical au ho i ies. T adi ionally ce i i ca ion was made using he p oduc de i ni ion, d awings, and ma ks he end o he ai c a design p ocess. Concu en Enginee ing s ill holds his idea and conside s he ai c a design only as he unc ional design, en iched wi h manu ac u ing cons ains and needs. 16.5 Collabo a i e Enginee ing Nowadays he aim is a design p ocess wi h a single eam ha c ea es a single deli - e able including bo h he unc ional design and indus ial design (Fig. 16.2 ). The main ad an age is a u he ime- o-ma ke educ ion applying i ual alida ion by means o i ual manu ac u ing echniques. I is a new me hodology ha needs new wo king p ocedu es and new PLM ools. 16.6 Analysis As-Is To-Be Cu en o “As Is” si ua ion (Fig. 16.3 ) shows an op imized unc ional design a ea wi h a clea deli e able: he p oduc DMU. The concu en p ocess closes he gap be ween unc ional design and indus ial design, and is in ended o p omo e “Design o Manu ac u ing” and “Design o Assembly.” The unc ional design deli e able, he “DMU as mas e ,” being a p o i able i em in he i s s ages o he li e- cycle, becomes o dec easing use wi h ime and meanwhile mos o he indus ial design asks a e s ill pape based. Fu u e o “To Be” si ua ion shows an op imized unc ional and indus ial design a ea wi h a clea deli e able: he iDMU [ 6 ]. The p e ious gap is elimina ed by he Fig. 16.2 Concu en iew s. collabo a i e iew collabo a i e way o building he iDMU and he i ual alida ion o i . The design ( unc ional and indus ial) deli e able, he “iDMU o all,” is a aluable i em along he whole li ecycle. The in o ma ion con ained in he iDMU can now be exploi ed by Sus aining, o p oduce shop l oo documen a ion in a wide a ie y o o ma s. This new collabo a i e design me hodology equi es also new p ocedu es. In his wo k we can only discuss he co e o he p ocedu es change, and his can be done wi hin his analysis As-Is To-Be. Cu en As-Is Concu en Design p ocedu es a e based in a well de i ned DMU li ecycle made o exhaus i ely de i ned ma u i y s a es. DMU ma u i y s a es a e con ols o he indus ial design asks. The di e en Indus ial design asks canno be s a ed un il he DMU eaches he co esponding ma u i y s a e. The e a e also p ocedu es con olling he e olu ion om a ma u i y s a e o he ollowing based on app o al o all he s akeholde s. This way, he indus ial design only can p og ess on he acks o he unc ional design, and p ocesses and esou ces li e- cycles a e less exhaus i ely de i ned. In he To-Be Collabo a i e P ocedu es, he ma u i y o p oduc , p ocesses and esou ces mus e ol e a he same ime. The p oduc DMU is no deli e ed a de i ned s a es o he indus ial design.
