Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

Detta examensarbete är resultatet av en utredning av produktionsbegränsningar och produktutveckling på Volvo Construction Equipment AB Component Division i Eskilstuna. Produktionssystemet på Volvo CE genomgår en stor förändring då det går från att fungera som en funktionell verkstad till att bli flödesinriktat. Detta gör att helt nya krav ställs på produkternas konstruktion och utformning. Det är nu inte möjligt att anpassa maskinerna eller operationsföljderna efter artikeln i samma utsträckning som tidigare, man kommer att vara tvungen att anpassa artiklarna efter produktionslinan. Därav har en litteraturstudie inom Concurrent Engineering gjorts som belyser hur man bör jobba som organisation och vilka verktyg man har till sitt förfogande, för att utveckla produktionsvänliga produkter.

This thesis has been conducted at Volvo Bussar ABunder a period of ten weeks. Within the organizationVolvo, the work is conducted with leaders and teamson every level; from production to top management.They have three tasks, besides executing their dailywork, they are expected to actively work on improvingtheir individual work as well as themselves as persons.The two latter are future value adding activities for theorganization. When doing so, however, it has beennoticed that they often lose the grasp of their dailywork. The question that consequently arises is whythis happens. Is it because of lack of time or it isbecause the co-workers do not have the competenceand simply do not know how they are to execute thethree tasks? Or, is it because the motivation to executethe three tasks is not enough? With this in regard, thestatement of issues for this bachelor thesis were thefollowing: how can the conditions for leaders and theteam be improved, in order for them to execute thesethree tasks.To find out why the execution of these threeassigments did not always succeed, the decision wastaken to conduct a survey and interview study in reallife and at the plants.

Den här undersökningen har studerat hur arbetsmotivationen ser ut på Volvo i Curitiba, Brasilien. Vilka faktorer medarbetarna får tillfredsställda och hur ledarskapet påverkar deras arbetsmotivation. Det finns forskning som pekar på skillnader i maktdistans i olika kulturer. Därför har vi undersökt hur relationen mellan ledare och medarbetare ser ut. Eftersom att det i västvärlden har skett en förändring i synen på arbetet ville vi se om denna förändring skett även i Brasilien.

Detta examensarbete är resultatet av en utredning av tvättning och rengöring av produkter som tillverkas på Volvo Construction Equipment Components AB i Eskilstuna. Arbetet är uppdelat på två huvudområden, tvättning i processen samt slutgiltig renhet. Skillnaderna mellan dessa är framförallt att det finns fastställda krav på den slutgiltiga renheten för artiklarna men en motsvarande märkning saknas för de olika tillverkningsstegen. Idag tvättas ungefär 70% av TMAs artiklar i en central tvättstation. I och med detta uppstår en hel del problem med ledtider och kvalitet.

 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.

Med detta examensarbete vill vi belysa problematiken runt tredimensionell fastighetsbildning. Som objekt har vi använt oss av ett bergrum på Liljeholmskajen i Stockholm..

This thesis was commissioned by Volvo Powertrain, where manufacturing and assembling of transmissions is performed, which is used in the company's trucks and buses. The thesis has consisted of a case study that intends to study the problem areas in the current proposed activities and continuous improvements in the assembly department in the Volvo Powertrain facility.In the current situation, the proposals that are submitted by the employees suggest mainly minor improvements. The proposals concern for example, labelling of materials boxes and holders for tools, which do not generate any significant profit for the company. Directors and executives want an increased amount of proposals with a more results-oriented type, in terms of reduced costs, time consumption and stops, and improved quality. The company would also deal with the problems that arise when implementing improvements in the production.

This report presents the results of a thesis in which the department PL Hus at Grontmij AB isstudied. The study has been done in order to locate problem areas in order to streamline andimprove the quality of working. The study was done by an engineering student from theDepartment of Industrial Management at KTH on behalf of Grontmij AB. The project extendedover a period of 20 weeks during spring 2011.In addition to the Department itself has two project managers in two different projects beenfollowed. The method used has been participant observation and was used to be able to comeclose to reality and thus find problem areas where there are opportunities for development.Validation was made through comments and opinions from workers at Grontmij AB, afterreading the reports analysis.Based on a system and holistic approach has parallels been drawn to the production systems suchas TPS (Toyota Production System) and lean production.

This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).

Bakgrund: Volvo Cars Body Components (VCBC) tillverkar och levererar karosskomponenter till Volvo Cars. För sex år sedan påbörjade VCBC sin implementering av lean production. För att beräkna de kostnader som uppstår i produktionen använder VCBC produktkalkyler. Representanter vid VCBC anser att företaget har problem med höga plåtlager, överproduktion samt problem med att se kostnadssamband. Ett value stream där förbättringsmöjligheter finns är Flöde 1 vid VCBC.

This thesis investigates management accounting systems in a Swedish health care environment. Through a qualitative case study of an activity-based cost accounting system that was introduced in 1994 at S:t Görans Sjukhus, a large Stockholm hospital, the following questions are addressed: What benefits can an activity-based cost accounting system offer the Swedish health care providers? What are the potential problems impeding the implementation of such a system? Main findings: an activity-based cost accounting system can improve the understanding of where costs are generated in the production processes. Comparisons between alternative production processes are improved, and the data may serve as a basis for internal pricing measures. Concerning the second question, difficulty in reconciliating the principles of economic control with the culture present in a hospital is identified as the main obstacle to a new management accounting system..

Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible. A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability. Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.

Inom måleriet på Volvo Lastvagnar, Umeå finns idag utrustning som hanterar hytterna med oidentifierade systemförluster och varierande kapacitet i grundlacksprocessen. Det är nödvändigt att ha kännedom om vilka begränsningar som finns i processen för att kunna optimera den på ett effektivt sätt. Utrustningen som avses är två hissar och en transportvagn som alla tre är automatiserade och som används för att hantera hytterna från utgång kylzon efter grundlack fram till KOB-bufferten innan täcklack. Målen med uppdraget är att identifiera systemförlusterna, beräkna kapacitet på utrustningen samt ta fram förslag som kan minimera alternativt eliminera systemförlusterna. Vid genomförandet har befintlig produktion i måleriet studerats. Litteraturstudie Lean production och Volvo Production System har utförts för att underlätta arbetet.Under arbetet genomfördes en tidsstudie som sedan sammanställdes för att användas för att identifiera systemförlusterna och beräkna utrustningens kapacitet.
