Abstract [en]

A common strategy which has in many cases become a necessity in product developing companies is to apply platform thinking to some extent. Engineer-to-order (ETO) companies are firms that need to invest in a significant amount engineering time in each product ordered by customers. These companies have in the past been known to not be fully able to apply platform strategies. An area of concern to product development is the design and manufacture of machine tools aimed for part manufacturing which is a large investment and a critical bottle neck. As a response to these challenges the design platform (DP) concept was developed which is founded on the re-use of company assets. This paper aims to investigate the application of the DP in a company designing and producing unique high-pressure die casting tools for different applications and customers. To enable companies of this character to utilize platform thinking to a higher degree and thus increase the efficiency in product development, a focus is set on modelling and managing relations within the DP. In addition, a PDM system setup is proposed together with an integrated support application for the realisation in industry.

Abstract [en]

Manufacturing companies are continuously faced with requirements regarding technology novelty, shorter time to market, a higher level of functionality, and lower prices on their products. This is especially the case for companies developing and manufacturing highly customized products, also known as engineer-to-order (ETO) companies. The traditional view of the product lifecycle introduces the customer only at the sale and distribution phase, which is often concerned with identifying and transferring customer needs into fixed specifications that guide the development of end-consumer products. In the ETO industry, however, the customer is involved already at the scoping and quotation stage, and a significant amount of engineering needs to be performed for every customer order. Thus, ETO companies cannot work according to the traditional model described above since specific requirements are set directly by the customer, or a detailed requirements specification is missing and must be developed in cooperation with the customer. It is not uncommon that products are developed in joint ventures with the customer and run for several years, during which requirements change.

Product platform approaches have been generally accepted in the industry to serve a wide product variety while maintaining business efficiency. However, how to apply a product platform approach in ETO companies that face the reality described above is a challenge. Product platform approaches tend to require focused development of the platform, which, in turn, requires some knowledge about the future variants to be derived from the platform. The research presented in this thesis investigates the state of art and practice in the industry regarding the challenges, needs, and current use of product platforms. To respond to the identified need, a product platform approach is proposed that expands the scope of what a product platform has traditionally contained. The purpose of this proposal is to aid the development of highly customized products when physical modules or component scalability do not suffice. The resulting approach, the Design Platform Approach (DPA), provides a coherent model and methodology for heterogeneous engineering assets to be used in product development, supporting the activity of designing and existing solutions. The approach is based on identifying and modelling generic product and process items, which are the generic building blocks of the product, its structure, and the process of designing them. The generic product and process items are associated with the generic assets governing their design. By describing engineering assets that are the outcome of technology and product development, such as finished designs, design guidelines, constraints etc., in a standardized format, the DPA successively evolves.

This thesis outlines the DPA in detail and presents cases of applications that have focused on different aspects of the approach. Tools to support the DPA are presented and evaluated in different kinds of industries along with the specific methods used and literature summarization.

Abstract [sv]

Tillverkande företag blir kontinuerligt utmanade med krav på kortare ledtider, lägre priser på sina produkter och en högre nivå av funktionalitet och teknik. Detta är särskilt fallet för företag som utvecklar och tillverkar högt kundanpassade produkter, även kända som engineer-to-order (ETO) företag. Den traditionella synen på produktlivscykeln introducerar kunden i försäljnings- och distributionsfasen, som ofta berör identifiering och överföring av kundbehov i kravspecifikationer som styr produktutvecklingen av produkter för slutkonsumenter. ETO-branschen skiljer sig i att kunden redan är involverad i offertstadiet och att en betydande mängd ingenjörsarbete behöver utföras för varje kundorder. ETO-företag kan således inte fungera som tidigare beskrivna företag eftersom specifika krav ställs direkt av kunden. Även motsatsen kan inträffa då en detaljerad kravspecifikation saknas och behöver utvecklas i samarbete med kunden. Det är inte ovanligt att produkter utvecklas i gemensamma projekt med kunden och att projekt drivs under flera år under vilka krav tenderar att ändras.

Plattformsstrategier har accepterats inom industrin för att effektivt kunna hantera ett brett produktsortiment samtidigt som företagets effektivitet upprätthålls. En utmaning är dock hur ETO företag som står inför den verklighet som beskrivs ovan bör applicera en plattformsstrategi. Plattformsmetoder tenderar att kräva en fokuserad utveckling av plattformen vilket i sin tur kräver viss kunskap om vilka framtida varianter som ska skapas från plattformen. Forskningen som presenteras i denna avhandling undersöker litteratur och praktik inom industrin gällande utmaningar, behov och användning av plattformar. För att svara på det identifierade behovet föreslås en plattformsmodell och metod som utökar omfattningen av vad en produktplattform traditionellt har varit. Syftet är att stödja utvecklingen av höganpassade produkter när fysiska moduler eller skalbara komponenter inte räcker till. Det resulterande tillvägagångssättet, Design Platform (DP) -modellen, ger ett sammanhängande sätt för att hantera ingenjörstillgångar som ska användas vid produktutveckling och inkluderar både konstruktionsprocessen samt befintliga produktlösningar. Tillvägagångssättet bygger på att identifiera och modellera den generiska produkten och processen som är produktens generiska byggstenar, dess struktur och dess process. Dessa kopplas samman med de generiska tillgångarna som stödjer konstruktion och återanvändning. Genom att beskriva ingenjörstillgångarna, som är resultatet av teknik och produktutveckling, som färdiga konstruktioner, riktlinjer för konstruktion, krav etc. i ett standardiserat format, utvecklas plattformen successivt.

Denna avhandling presenterar DP-modellen och implementationer som har fokuserat på olika aspekter av DP-modellen. Flera verktyg för att stödja DP-modellen presenteras och utvärderas i olika branscher samt diskuteras i ljuset av den forskningsmetodik och litteratur.
