Simulation based product development and competitiveness : How does a simulation based product development affect a company’s overall future competitiveness?

Bergström, Frida, Björkvall, Marika January 2015 (has links)
The gradually increasing competition that occurs in mature markets, pushes the companies to consider new ways of competing. The more mature the market becomes the higher level of competitive fulfillment and edge is needed. E.g. for Scania the dimension high quality was until now considered a competitive advantage, but is currently evolving towards a dimension that is necessary to fulfill to even act within the market. Thus, companies such as Scania have to push their limits everywhere possible across their organization. One way to push the limits of R&D and product development (PD) is, based on this thesis and other work, implementing a simulation based product development (SBPD) process. The aim of this thesis has been, by applying a quality function deployment (QFD) model, to show the influence a SBPD process can have on increased competitiveness. By combining published literature within the field with empirical results mostly gained from interviews, nine components representing a SBPD process could be found. These components were characterized in the following categories: IT-infrastructure, design, model & test, and organizational. Depending on the level of fulfillment of these components the SBPD process is more or less implemented within the company. The two components that are considered the most important for Scania in terms of both increased competitiveness and a possible transition towards a SBPD process are Virtual representa-tion of the product and the process throughout the whole PD process and A model driven/model based approach. The work of this thesis has also shown, in correlations with previous published literature, that a SBPD process can significantly decrease the lead-time and cost of development, and at the same time increase the knowledge about the product and the process. The research has also shown that a SBPD process can considerably improve both the internal and the external collaboration. However attaining such a process where these competitive advantages can be gained affects the whole organization, the way development is performed and also the way resources are used. A fully implemented SBPD process has been shown to positively impact the following competitive dimensions; Frequency of product introductions, Lead-time of development, PD process flexibility, Degree of innovation, Customization of the offer, Collaboration with internal and external partners, Knowledge about products and processes, R&D cost, manufacturing cost, Focus on customers operational economics, Product quality, Product safety and Focus on environmental sustainability of the product & the processes. But, to get a positive impact on all these dimensions the components representing a SBPD process must be implemented and applied. Furthermore, this thesis also provides a framework for other companies to evaluate the impact a SBPD process can have on their competitiveness. The analysis model aims to guide companies that want to adopt a SBPD process. The framework can indicate how a SBPD process would impact the firm's competitive strategy. But also to provide guidance to which components that would be more important to implement in order to reach a competitive SBPD process. / Den gradvis ökande konkurrens som uppstår på mogna marknader driver företagen att finna nya sätt att konkurrera. Ju mer mogen marknaden blir desto högre blir kraven på konkurrens. För Scania har faktorn hög kvalitet tills nu betraktas som en konkurrensfördel, men utveckling sker istället mot att det kommer att vara en faktor som är nödvändig att uppfylla för att ens kunna agera på marknaden. Företag som Scania måste således utvecklas över hela organisationen. Ett sätt att tänja på gränserna för FoU och produktutveckling (PD) är, baserat på detta arbete och annan tidigare forskning, att genomföra en förändring mot en simulering baserad produktutvecklings-process (SBPD). Syftet med detta examensarbete har varit att, genom att tillämpa en quality function deployment (QFD) modell, visa effekten en SBPD-process kan ha på ökad konkurrenskraft. Genom att kombinera tidigare publicerad litteratur inom området med empiriska resultat, mestadels insamlat genom intervjuer, kunde nio komponenter som utgör en SBPD-process finnas. Dessa komponenter karakteriserades i följande kategorier: IT-infrastruktur, design, modellera och testa och organisatorisk. Beroende på graden av uppfyllnad på dessa komponenter blir den SBPD-processen mer eller mindre implementerad inom företaget. De två komponenterna som anses viktigast för Scania i form av både ökad konkurrenskraft och en eventuell övergång till en SBPD-process är Virtuell representation av produkten och processen genom hela PD-processen och Ett modellbaserat/ modelldrivet arbetssätt används. Arbetet har också visat i korrelation med tidigare publicerad litteratur, att en SBPD-process kommer att minska ledtiden och kostnaden för utveckling avsevärt och samtidigt öka kunskapen om produkten och processen. Denna studie har också visat att en SBPD-process kan förbättra både interna och externa samarbeten. Men att uppnå en sådan process där dessa konkurrens-fördelar kan vinnas kommer att påverka hela organisationen, det sätt som utveckling utförs på och också hur resurserna används. En fullt implementerad SBPD-process har visat positivt påverkan följande konkurrens faktorer; frekvens av produktlanseringar, ledtiden för utveckling, PD-processflexibilitet, innovationsgrad, anpassning av erbjudandet, samarbete med interna och externa partners, kunskap om produkter och processer, FoU kostnader, tillverkningskostnad, fokus på kundernas driftsekonomi, produktkvalitet, produktsäkerhet och miljöpåverkan av både produkten och processen. För att få en positiv inverkan på alla dessa faktorer måste alla komponenter som utgör en SBPD-process implementeras och tillämpas. Dessutom så presenteras även ett ramverk för andra företag att utvärdera effekterna en SBPD-process skulle ha på deras konkurrenskraft. Analysmodellen syftar till att vägleda företag som vill övergå till en SBPD-process. Ramverket kan ange hur en SBPD-process skulle kunna påverka företagets konkurrensstrategi men också ge vägledning om vilka komponenter som kan vara viktigare att börja implementera för att nå en konkurrenskraftig SBPD-process.

Designing Feelings into Products : Integrating Kansei Engineering Methodology in Product Development

Schütte, Simon January 2002 (has links)
Tendencies in product development of today make it likely that many future products will be functional equivalent and therefore hard to distinguish between for the customer. Customers will decide by highly subjective criteria which product to purchase. One task for product development in this context is to be able to capture the customer’s considerations and feelings of products and translate these emotional aspects into concrete product design. Today a number of different methods, such as Quality Function Deployment (QFD), Semantical Environment Description (SMB), Conjoint Analysis and Kansei Engineering exist and are used in practical applications. The purpose of this thesis is to understand and apply Kansei Engineering methodology and explore ways to integrate the methodology into an industrial product development process. This was done by conducting a study on forklift trucks in different European countries and business areas and by exploring ways of integrating Kansei Engineering in product development processes. The number of Kansei words collected was reduced based on the result of a pilot study using a combination of different tools. A computerized data collection method was used in combination with a modified VAS-scale in order to reduce the time for filling out the evaluation forms The results of the study in the visited Northern and Middle European companies make it evident that Kansei Engineering has to be adapted in several aspects to the circumstances in each situation. The data showed that there are differences in attitude towards reach trucks in the different European countries. These results were used in order to adapt the product requirements for each specific country. Starting at Cooper’s stage gate model Kansei Engineering was applied on a macro level, a micro level and for verifying purpose. Using QFD, Kansei Engineering helps to identify customer needs their importance and the technical responses as well as to conduct benchmarking and to connect the customer needs mathematically to the technical responses. This study of Kansei Engineering revealed that there was no general model on the methodology available in English literature. Outgoing from a previous flowchart, a conceptual framework of Kansei Engineering was developed integrating the existing Kansei Engineering Types and future tools. / <p>ISRN/Report code: LiU-Tek-Lic 2002:19</p>

Förstudie av transportsystem för spillmaterial : Fallstudie på INP Förpackningar AB / Pre study of transport system for waste material

Åkesson, Emma, Gunnarsson, David January 2019 (has links)
Det finns olika tekniska lösningar för hantering, transport och återvinning av plastindustrins spillmaterial, men vilken metod som är mest lämpad för en specifik industri är svårt att avgöra. Syftet med studien var att få ökad kunskap och förståelse för hur faktorer som arbetsmiljöpåverkan, miljöpåverkan, funktion, flödeseffektivitet och investeringskostnad påverkar val av transportlösning för spillmaterial. Baserat på dessa faktorer är studiens mål att genom en förstudie presentera ett beslutsunderlag för en eventuell investering. För att finna den mest lämpade transportlösningen och förstå det grundläggande problemet med det nuvarande systemet genomfördes en nulägesanalys på fallföretaget. Informationen låg senare till grund när en undersökning av olika lösningsalternativ på marknaden gjordes. För att urskilja de mer relevanta alternativen för fallföretaget användes en kravspecifikation samt Kanomodellen. När de relevanta lösningarna valts ut jämfördes dessa mot varandra genom en QFD-matris för identifiering av den mest lämpliga transportlösningen. Resultatet av studien indikerade genom en QFD-matris att det manuella systemet var att föredra för fallföretaget.

Avaliação de desempenho em projetos complexos: uma abordagem multidimensional. / Complex project performance evaluation: a multidimensional approach.

Campos, André Vidal 20 May 2009 (has links)
Esta dissertação apresenta um estudo de avaliação de desempenho de projetos a partir de uma estrutura multidimensional que engloba custo, prazo e qualidade do produto final do projeto. As fundações para o desenvolvimento desta abordagem multidimensional estão em um modelo que integra o conceito de Gerenciamento do Valor Agregado (EVM Earned Value Management) à Engenharia de Sistemas e ao Desdobramento da Função Qualidade (QFD Quality Funcion Deployment). A tradução de requisitos do cliente para requisitos técnicos é alicerçada no Desdobramento da Função Qualidade (QFD Quality Funcion Deployment), a alocação de requisitos técnicos em uma Estrutura Analítica de Projeto (WBS Work Breakdown Structure) é baseada em Engenharia de Sistemas e finalmente a integração desta base com as técnicas de planejamento e controle de projetos do Gerenciamento do Valor Agregado (EVM Earned Value Management) formam o Modelo Multidimensional de Desempenho de Projetos (MPPM - Multdidimensional Project Performance Model). Esta integração de disciplinas de qualidade, engenharia de sistemas e gerenciamento de projetos, que formam o MPPM, visa avaliar custo, prazo e qualidade do produto final de um projeto de forma integrada e simultânea. A parte empírica é realizada em duas etapas, sendo a primeira a simulação de uso do modelo a um projeto real já concluído e a segunda etapa estudo multicaso. A simulação da aplicação do modelo em um projeto real busca avaliar as dificuldades de aplicação, bem como avaliar as lacunas de desempenho do projeto a partir de uma visão multidimensional. Por fim, apresenta-se um estudo multicaso, realizado em seis empresas de grande porte de setores industriais distintos, que atuam no Brasil e desenvolvem projetos complexos. O objetivo desse estudo é fazer um levantamento das práticas de avaliação de desempenho em projetos, bem como avaliar se as empresas estudadas estariam prontas para a utilização do modelo multidimensional desenvolvido neste trabalho. O trabalho conclui que é possível a aplicação de um modelo multidimensional integrado como o MPPM para projetos com produtos complexos. Sua aplicação exige uma disciplina com a captura e desdobramento dos requisitos do cliente que não é usual nas práticas de gerenciamento de projetos das empresas pesquisadas. Por isso, a aplicação do modelo depende de uma considerável evolução da forma como as empresas gerenciam projetos e lidam com os requisitos de clientes para o produto do projeto. / This dissertation presents a study of project performance evaluation through the development of a multidimensional model that integrates the dimensions of cost, schedule and quality of the project end product. The foundation for the development of this multidimensional approach is a model that integrates the Earned Value Management (EVM) concept with Systems Engineering and the Quality Function Deployment (QFD). The customer requirements translation to technical requirements from the Quality Function Deployment (QFD), the allocation of technical requirements to a Systems Engineering based work breakdown structure (WBS) and finally the integration of this basis with the EVM techniques of planning and controlling projects along its lifecycle build the Multidimensional Project Performance Model (MPPM). This integration of quality, systems engineering and project management disciplines, that results in the MPPM, is capable of an integrated and simultaneous evaluation of cost, schedule and quality of the project end product. The empiric study is divided in two parts, the fist one simulates the application of the MPPM to a real known project, the second is a multicase study. The MPPM simulation with a real project shows the difficulties and barriers to the application of such model, as well as the gaps of a project performance evaluation based on a multidimensional vision. Finally a multi-case study of practices of project performance evaluation with six large companies of different industries segments dealing with complex projects in Brazil is developed. This multi-case study objective is to raise companies practices on project performance evaluation and also to evaluate if the studied companies are ready for the implementation of a multidimensional project performance model as the MPPM. The dissertation conclusion is that it is possible to apply a multidimensional project performance model such as the MPPM for projects with complex products. The model application requires discipline on the customer requirements elicitation and deployment. This discipline is not commonly found on studied companies practices of project management. The MPPM application depends on a considerable evolution of the companies project management methods, as well as the way these companies deal with customer requirements of the project end product.

Verification of CEVT Steering System Specification

Lundström, Adam January 2019 (has links)
This thesis covers the development of a component specification for the steering system of vehicles engineered by CEVT. This includes the components steering column, intermediate shaft, steering gear and tie rods. Due to the reuse of requirements on the component specification from previous projects it now lacks connection to customer needs. A verification of the component specification is necessary to ensure that no redundant or unnecessary requirements are present. The verification was performed through a comparison between a newly established specification and the current one. Identified customer needs were gathered on complete vehicle level and classified according to customer satisfaction with respect to implementation according to the Kano model. The subjective customer needs were translated into objective, quantifiable metrics on complete vehicle level that was then decomposed onto component level. Customer needs and metrics were then correlated against each other and visualized through the House of Quality matrix. Numeric targets for the metrics were based on its impact on customer satisfaction. This resulted in 50 identified metrics connected to the steering column and 58 metrics connected to the steering gear. The comparison resulted in 22 deviations between the new and current specification where 8 metrics was identified for further investigation. Further development would include investigation of these 8 identified metrics and relate targets to competitors’ performance.

Proposition et développement d'une approche pour la maîtrise conjointe qualité/coût lors de la conception et de l'industrialisation du produit

Hassan, Alaa 16 April 2010 (has links) (PDF)
Le besoin de compétitivité impose aujourd'hui de concevoir plus rapidement, mieux et moins cher que les concurrents. Dans ce contexte, la prise en compte de l'ensemble des contraintes du produit dépends du retour des indicateurs de performance (coût, risque, qualité, délai,...). Il est donc important de bien évaluer ces indicateurs afin de retourner des informations robustes et cohérentes qui permettent de prendre une bonne décision pour piloter le cycle de développement du produit de sort qu'on obtient un meilleur rapport qualité/coût. L'interopérabilité des approches QFD, FMEA et KCs a été étudiée afin de les exploiter dans un seul cadre de maîtrise de la qualité pour assurer l'homogénéité et la cohérence des indicateurs de la qualité. Le coût a été pris en compte en proposant l'approche CbFMEA, basée sur FMEA classique, qui permet d'estimer le coût de non-qualité afin d'évaluer la gravité financière des défaillances du produit. Ce coût a été ajouté au coût de fabrication du produit estimé par la méthode ABC. L'approche du coût (CbFMEA/ABC) a été couplée à l'approche de la qualité (QFD/FMEA/KCs) résultant une approche conjointe qualité/coût illustrée par un diagramme d'activités. Un modèle de données de l'approche conjointe qualité/coût a été proposé est une maquette informatique a été développée afin de valider les concepts et le modèle proposés. Une application de cette approche a été illustrée dans la phase de pré-gamme d'usinage via un cas d'études. Cette application est nommée QCCPP, elle fournit des indicateurs de capabilité, de risques et du coût. L'objectif est l'aide à la décision lors du choix multicritères des ressources d'usinage pour l'amélioration conjointe de rapport qualité/coût du produit.

Detta projekt har haft som mål att utveckla produktdisplayer för användning i butiker i syfte att exponera produkter som smycken, solglasögon eller liknande. Projektet är utfört som ett examensarbete vid Mälardalens Högskola inom produktutveckling med inriktning formgivning. Bakgrunden till projektet är att företaget X-ponent vill utforska en ny marknad. Det vill säga konsumentmarknaden istället för sin vanliga inriktning på industri. X-ponent har fått förfrågningar om produktdisplayer av mindre tillverkare av smycken och säljer idag en enkel variant till dessa. Uppdraget har gått ut på att ta fram tre koncept på produktdisplayer ett med ett eget användningsområde; en väggdisplay, för att kunna användas vid vägg; en golv display, för användning på golvet i butiken; och en bordsdisplay, att kunna ställa på bord eller disk. Displayens syfte skulle vara att exponera produkten och locka folk att köpa varför konsument psykologi och marknadsföring i butik studerades. Även semiotik spelade stor roll i konceptens formgivning och studerades noga. För att ta reda på marknadens krav och egenskaper användarna ansåg vara bra och dåligt med dagens produkter utfördes en marknadsundersökning i butikerna i Tuna Park i Eskilstuna och på Dustins Elektronikmässa i Annexet i Stockholm. Även en utförlig konkurrensanalys utfördes på konkurrerande produkter. Under projektets gång har ett flertal produktutvecklings verktyg används som, funktionsanalys, FEMA och CAD (genom SolidWorks). Arbetsmetoden har varit att ta fram en mängd olika koncept för att sedan metodiskt sålla bort, förbättra och tillslut välja ut slutgilltliga koncept. För att göra bästa möjliga val använde jag mig av flera beprövade verktyg. Som Beslutsmatriser, PUGH och QFD. Utöver dessa verktyg hade jag flera diskussioner med uppdragsgivare och handledare. En viktig del har varit att presentera koncept som både uppfyller marknadens och uppdragsgivarens krav samtidigt som det är så hållbart för miljön som möjligt. för att göra detta möjligt studerades "sustainable design" (hållbar design). De slutgiltiga koncepten presenterades som renderade bilder. Dessa renderades i programmet 3D-Studio max. En säljande produktfolder skapades för att ge koncepten extra tyngd. Även en modell av väggkonceptet togs fram.
