The aim of this project is to develop an auxiliary office chair, which favorably will compete with the existing chairs on the market. Evolutions of ergonomical survey in the work environment and on the configuration of offices require new products which fulfill the requirements properly. In order to achieve it a survey about office chairs has been carried out: types, characteristics, ways of usage and products on the market besides a large antropometrical study and ergonomics related to work area study. The result is an auxillary office chair which improves significatively in ergonomics compared with such chairs found in the market survey. Moreover it is achieved a great improvement refering to apilability stackable characteristics and manufacturing, as this chair has good features as easily cleanning and innovative aesthetics and no high manufacturing cost. That means an easily marketed product.

This thesis presents a concept for improving a wood roof from an acoustical point of view. The normative related to noise is going to demand higher levels for airborne insulation and also for noise impacts so it is necessary to improve the acoustical part of these constructive elements. A deep study of acoustics and also of roofs: parts, functions, manufacturing… and materials to make them has helped to solve the problem. The knowledge of how sound is produced, propagated and how it can be reduced has given a solution to the problem (concepts creation and choice). The result is a prefabricated wood sandwich panel with a rock wool and rubber core which is enough justified to perform all normative related to noise and sound as well as other functions like supporting, thermal purposes etc. All the parts have been explained adequately and also it has been suggested how the module can be constructed as well as the assembly in the final structure.

På en global marknad med allt tightare vinstmarginaler har fokus på produktkostnad ökat. I produktutvecklingsprocessen har ett allt större behov av förbättrade arbetssätt kring produktkostnadskalkylering uppstått för att företag skall vara konkurrenskraftiga. Produktkostnad är en väsentlig del av ett företags kostnadsmassa. Under en produktutvecklingsprocess tidiga skeden saknas ofta etablerade metoder och processer för beräkning av produktens kostnad. Speciellt svårt är det att uppskatta produktkostnad i tidiga faser av produktutvecklingsprocessen då osäkerheten kring konstruktionen är stor. Detta kan få till följd att till exempel avsaknad av vetskap kring materialkostnad eller investeringsbehov uppstår. Målet med denna uppsats är att hjälpa, utvärdera och supportera kring förbättringar av arbetssätt inom produktutvecklingsprojekten när det kommer till produktkostnadskalkylering. Syftet med detta examensarbete är att skapa en passande finansiell modell som kan användas vid val av koncept i tidiga stadier av produktutvecklingsprocessen för att säkerställa högsta möjliga lönsamhet för Volvo Construction Equipment. För att lösa detta problem så har insamling av teori i form av böcker, artiklar samt rapporter genomförts med fokus på produktutveckling och produktkostnad. Teoristudien påvisade mycket material kring produktutvecklingsprocessen men mindre kring detaljerad produktkostnadskalkylering. Den empiriska delen har genomförts i samarbete med Volvo Construction Equipment med syfte att få ökad förståelse för problemställningar i dess verkliga miljö. Från intervjuer, dokumentation samt övrig insamling så påvisades att förbättringspotential fanns kring produktkostnadskalkylering i tidiga faser av produktutvecklingsprojekt. För ytterligare ökad förståelse genomfördes en strukturerad jämförelse samt en diskussion kring respektive område av teori och empiri. Resultatet av jämförelsen visar att Volvo Construction Equipments hantering av problem korrelerar med den teori som existerar i uppsatsen. I de situationer där Volvo avviker från teorin så finns orsaker till att företaget inte väljer att följa denna. För att förbättra processen kring produktutveckling och produktkostnadskalkylering på Volvo Construction Equipment skapades en kalkylmodell. Modellen applicerades konkret i ett pågående produktutvecklingsprojekt i företaget och gav möjlighet till uppföljning av utvecklingen av produktkostnaden under de olika faserna av projektet. / On a global market with tighter gross margins the focus on product cost have increased. A demand for improved methods within product cost calculations in the product development process is important to sustain competitive. Product cost is a vital part of a company’s cost base. During a product development process early stage there is often a lack of established methods and processes for calculation of the product cost. Especially difficult is it to estimate product cost in early stages of the product development process when the uncertainty around the construction of the product is big. That might lead to lack of knowledge around material cost and need of investments occur. The goal with this thesis is to help, evaluate and support around improvements within the product development projects when it comes to product cost calculation. The purpose of this thesis is to create a suitable financial model that is applicable when choosing concept in early stages of the product development process to sustain highest possible profitability for Volvo Construction Equipment. To solve this problem a collection of theory in form of books, articles and reports has been made with focus on product development and product cost. The theory part showed a lot of material around the product development process but less data around detailed product cost calculation. The empirical part has been created in cooperation with Volvo Construction Equipment with purpose to increase knowledge for problems in its natural environment. From interviews, documentations and other collection has shown that improvement potential was found for product cost calculations in early stages of product development project. For further increased understanding a structured comparison and a discussion around each area of theory and empirical data was created. The result of the comparison shows that Volvo Construction Equipment’s handling of problems correlates with the theory that exists in the thesis. To improve the process with product development and product cost calculation at Volvo Construction Equipment a calculation model was created. The model was applied in a real product development project in the company and gave opportunity for estimations of the development of the product cost during the different stages of the project.
