The aim for this thesis was to develop a proposal of documentation, containing rules and procedures, which JernströmOffset needs to acquire the Certified Graphic Production certification. A fundamental part was to study the materialissued by Sveriges Grafiska Mediaförening, to clarify the requirements that must be met to obtain the certification. Therecommendations found in the CGP material must also be considered.Based on the requirements and recommendations of Certified Graphic Production, a mapping of the workflows atJernström Offset was performed. It was done by interviewing employees from different departments at the company,this to get a clear understanding of the operations carried out throughout the production flow and the final qualityfollow-up.During our reviewing process we found that a number of changes, in terms of working environment and practices,must be made at the company. As a result of this we propose some appropriate actions to be implemented.The documentation was finally written, through the requirements and recommendations of Certified GraphicProduction and then applied to Jernström Offset’s work procedures.

The question formulation in the essay brought up whether Clas Ohlson works today with their graphical productionflow and if that way of working leads to a desirable result in press. After a dialogue with Clas Ohlson it emerged thatthey had certain problems with the material that came out of the printing presses. Certain colours were not reproducedaccording to the stated values that had been developed. In March -08 an analysis of the graphical production flowspresent situation were done at Clas Ohlsons in order to find out how they worked with their production of print materials.In the analysis, their way to work with color spaces, displays, ICC-profiles, PDF-exports, pictures and printerswere examined. Occasional interviews were also implemented with responsible personnel about how they worked withdifferent aspects.Deficiencies were found on almost all examined parts in their graphical production flow. Wrong colorspaces andCMYK-profiles was used in big extent, the displays where uncalibrated or incorrectly calibrated, wrong PDF-presetswas used frequently and it also showed that six different suppliers for their printing materials were used. The solutionsthat were relevant for the problems and defects were later on presented as proposals on measures.

Setup time reduction facilitate the flexibility needed for just-in-time production. An integrated steel mill with meltshop, continuous caster and hot rolling mill is often operated as decoupled processes. Setup time reduction provides the flexibility needed to reduce buffering, shorten lead times and create an integrated process flow. The interdependency of setup times, process flexibility and integration were analysed through system dynamics simulation. The results showed significant reductions of energy consumption and tied capital. It was concluded that setup time reduction in the hot strip mill can aid process integration and hence improve production economy while reducing environmental impact.

This thesis is about new digital moving image recording technologies and how they augment the distribution of creativity and the flexibility in moving image production systems, but also impose constraints on how images flow through the production system. The central concept developed in this thesis is ‘creative space’ which links quality and efficiency in moving image production to time for creative work, capacity of digital tools, user skills and the constitution of digital moving image material. The empirical evidence of this thesis is primarily based on semi-structured interviews conducted with Swedish film and TV production representatives.This thesis highlights the importance of pre-production technical planning and proposes a design management support tool (MI-FLOW) as a way to leverage functional workflows that is a prerequisite for efficient and cost effective moving image production.

Idag är det vanligt att företagen konkurrerar med produkter som innefattar en fysisk vara som har utvidgats med olika tjänster för att kunna tillfredsställa kundens behov. I takt med detta ökar produkternas komplexitet och högre krav ställs på leverantörerna. Denna utveckling har lett till att många företag som tillverkar produkter med hög variation måste arbeta helt kundorderstyrt för att kunna tillgodose kundernas ökande krav. Företagen som tillverkar dessa komplexa produkter har en tillverkning som karaktäriseras av hög variation och låg volym vilket benämns med förkortningen HVLV. Utmaningen för dessa HVLV-företag ligger i att ha en hög produktmixflexibilitet med så låg resursanvändning som möjligt. För att effektivisera verksamheten har många företag därför intresserat sig för Lean production som har visat sig vara ett framgångsrikt koncept för tillverkande företag runt om i världen som effektiviserat sin produktion. Ett flertal artiklar har uppmärksammat begränsningar vid implementeringen av Lean production i HVLV-miljöer. Artiklar pekar vidare på behovet av ytterligare forskning kring Lean productions applicerbarhet i HVLV-miljöer och detta var uppkomsten till examensarbetets bakgrund och syfte. En fallstudie har genomförts på Tibrokök som är ett företag med en helt kundorderstyrd produktion som kännetecknas av HVLV. Med hjälp av fallstudien syftar examensarbetet till att undersöka om verktygen processkartläggning inkl. tidsstudier och layoutflödesdiagram kan bidra till att skapa förutsättningar för implementering av Lean production i en enskild tillverkningsprocess i en HVLV-miljö. Trots att verktygen har behövt anpassas något så anses de ha varit användbara och bidragande till skapandet av förutsättningar för implementering av Lean production i denna HVLV-miljö. Detta eftersom vi kunde identifiera många orsaker till slöseri samt ta fram ett förslag som skapar effektiviseringar av Tibroköks ytbehandlingsprocess i det framtida läget.
