Detta examensarbete genomfördes i samarbete med m4solutions AB, Halmstad, och Volvo Buses AB, Göteborg.Då Volvo önskar att minska totalkostnaden för tillverkning av luftintag, utan nedsatt prestanda som konsekvens, krävs undersökningar om hur väl dagens intag fungerar och vad som kan förbättras, samt planering av utvecklingsarbetet. För att underlätta för kommande förbättringsarbete har detta examensarbete undersökt vilket underlag och vilka kompetenser som krävs för att genomföra detta arbete. Resultatet av denna undersökning är en instruktion fylld med redskap och information vilket skall stöda Volvo Buses AB vid kommande arbetet att optimera luftintaget. Eftersom Volvo AB ingår i fordonsbranschen är det lämpligt att forma vår instruktion utefter ISO/TS 16949:2009 standarden, för produktutveckling inom fordonsindustrin, och Volvo?s egna metodik, Global Development Process, för produktutveckling. Studien innefattar flödessimuleringar, marknadsundersökningar och kriterieframtagning, samt analyser och utvärdering av samtlig tillgänglig information. Tillsammans gav detta en övergripande bild över luftintagets funktionalitet och prestanda, vilket i sin tur belyser vilka aktiviteter som är nödvändiga att föreslå i den slutgiltiga instruktionen..

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

Volvo Construction Equipment AB, Volvo CE, är en global tillverkare av entreprenadmaskiner. Detta exjobb fokuserar på batterierna i dessa entreprenadmaskiner som försörjer maskinens elsystem och startmotor vid start.Med dagens teknik ställs nya krav på strömförsörjning i entreprenadmaskiner. Den största skillnaden är att förbrukare är igång när motorn är avstängd och strömförsörjningen kommer enbart från batteriet. Ett startbatteri av bly-syra typ är inte konstruerad för detta användningsfall. Volvo CE jobbar därför med att ta fram kunskap om hur laddningen i batterierna används och cyklas under drift.Frågeställning om vilka parametrar och trender som är relevanta för att utvärdera batteriladdning har behandlats i detta arbete.

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

Rapporten undersöker Volvo Construction Equipment Components axelmontering för axlar till Dumper och Hjullastare. Arbetet har utförts med intervjuer, studiebesök på andra fabriker och en detaljerad studie av monteringsavdelningen och dess angränsande avdelningar vilka levererar artiklar till monteringsstationerna. Undersökningen har resulterat i ett förslag där fördelarna av en stationsbaserad montering och fördelarna med en linjemontering kombinerats. Arbetet presenteras i rapporten och i en dator animerad 3D simulering av förslaget till en ny monteringslayout. Jag anser att Volvo CE Components och montörerna på monteringsavdelningen skulle gynnas av monteringslayouten som redovisas i rapporten..

Background: Since the coining of the phrase lean production by Womack, Jones and Roos in 1990, this mass production system of Japanese origin has been implemented in a multitude of organizations throughout the world, the results being predominantly positive from a financial point of view. The possibly negative effects of mass production on worker motivation have been discussed since quality of work life became an important political issue in Sweden in the 1970?s. As the popularity of lean service is now increasing, there are still unresolved issues regarding the transferability of a mass production system to the service industry, particularly with regards to the motivation of service employees.Purpose: The purpose of our thesis is to study the lean system of a Swedish bank, SEB Way, from a management- as well as an employee perspective in order to describe how lean may affect the work motivation of service employees.Research procedure: The study is empirically based on observations and interviews on multiple hierarchical levels at SEB. We have conducted a total of 13 interviews with front line employees at SEB, with the central SEB Way team as well as two external lean specialists.Results: The study indicates that SEB Way has little direct influence on the intrinsic work motivation of the SEB front line employees, as work motivation was present prior to the implementation of lean.

Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met.

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

Syftet med detta examensarbete är att på uppdrag av Volvo Construction Equipment hitta en metod för att hantera och kategorisera idéflödet i deras idéhanteringssystem Interact. Den metod som användes var kvalitativ innehållsanalys. Slutsatsen är att metoden gick att använda för att kategorisera idéflödet men att ett material som sträcker sig över många ämnen tenderar att sänka tillförlitligheten på resultatet. Vidare bedöms materialet som detta arbete har producerat kunna användas för att bättre ta tillvara på idéer, vilket uppskattas av Volvo Construction Equipment..
