Vägen till Lean Production : Historien bakom Lean och dess nutida användning
I dagens samhälle ställs hårda krav på resultatförbättringar i företag och industrier. Det är vanligt att företag tar hjälp av någon eller några av de ledningsverktyg som finns utvecklade i just detta syfte, Lean Production är ett av dessa verktyg. Syftet med denna rapport är att ge en historisk bakgrund till Lean Production och att undersöka vilka tillvägagångssätt tre företag har valt för att implementera Lean i sin verksamhet. Vidare skall författarna undersöka om det finns några likheter mellan dessa tillvägagångssätt och Toyotas produktionssystem (TPS).Utvecklingen till det som idag benämns som Lean började redan 1911 då Fredrick Winslow Taylor presenterade sin artikel ?Principles of Scientific Management?.
Användbarhetsutvärdering av en grafiskt visualiserad patientjournal
First-year students at Linköping University have developed a prototype that graphically visualizes a medical record in a new way. The customer of that project was the Department of Biomedical Engineering at Linköping University. They now want a usability evaluation to be performed of the prototype. The prototype is to be used by employees in the public health care and is supposed to be used on a small portable unit with a multi-touch interface. For this reason the prototype will be used as a complement to existing systems when the users work near the patients.
Marknadsundersökning: Lämpliga flygplan med avseende på start- och landningssträckor för Bunge flygfält
In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.
Framtagandet av ett företags visuella produktidentitet
Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.
The Trivial Pursuit: Den modererande effekten av kunskap och engagemang på utvärderingen av produkter med triviala attribut.
Research has concluded that meaningless differentiation with trivial attributes sometimes can be a successful strategy. However, the effect varies with respect to certain aspects such as the price of the product and the decision context. How the characteristics of the consumer influence the effect of trivial attributes has until now been unknown. This thesis investigates how the consumer?s level of knowledge and personal involvement influence the effects of trivial attributes on product preferences and product attitudes.

Aspect Analyzer: Ett verktyg för automatiserad exekveringstidsanalys av komponenter och aspekter
The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.
Produktutveckling med hjälp och stöd för teknisk projektledning : - en kvalitativ studie av tre högteknologiska företag.
Due to an increasing global market with a growing competition and an escalating technologydevelopment the demands on companies today are increasing. To maximise the output fromtheir recourses they need to be more efficient. The research on product development and how toensure the efficiencies in the process are extensive and companies could by adapting andimplementing the result of this research use its benefits.This master thesis is made for Knightec AB with the aims that through interviews anddiscussions with three companies investigate, collate, justify and give proposals for productdevelopment process together with supporting methods and procedures for technical projectmanagement. Besides Knightec AB three other companies located in Sweden has beenparticipating in this study. Through semi structured interviews and discussions in focus groupsinformation from the three involved companies were obtained.
Ett tydligare System C2 : Användargränssnittsutveckling med stöd av användarcentrerade metoder
User friendly and usable are two words that are often mentioned in the context of marketing new products. By doing so it adds an extra sense of quality to the product. The meaning of these words is therefore something that every product wants. But what is it that makes a product usable and user friendly? What methodology exists formaking sure that a product is usable? Does it exist applicable processes to ensure user centered development? These questions together with a practical example are parts of what will be addressed in this report.The thesis was carried out for C2 Management, a company that works with supporting other companies in their work with quality and constant improvements.
Kunskapso?verfo?ring inom franchisena?tverk : En studie av utveckling och o?verfo?ring av kunskap inom franchisena?tverk
This case study has been conducted within the Swedish fitness chain World Class to explore the opportunities for knowledge development and transfers within franchise networks. We have interviewed the product manager at the World Class headquarter, the owner of a franchise club and a local product manager from the same facility. Our finding indicates that various forms of knowledge transfer occur within the World Class network, particularly in product development and sales. The transfer occurs within the framework set by World Class with regularly scheduled meetings. In addition informal networks provide other means of knowledge exchange between some units.

Integration av PLM och CAD i komplex produktutveckling : En utredning av Scanias framtida systemmiljö för produktdatahantering
In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.
Kan implementering av Lean leda till effektiviseringar i skandinavisk sjukvård?
AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects. We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process. To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.
Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
Överraskning ? Tidlös eller totalt omkastad?
This essay deals with the principle of surprise warfare and its development as well as the adaptation of military action that had to be made to surprise the opponent in the modern era.The concept of surprise is divided into its components in order to clarify what is required to implement a surprising maneuver, to understand the complex concept and form a theoretical framework for gathering facts in the case study.Development and adaption are demonstrated by a comparative case study where Pearl Harbor illustrates an example of historical surprise and Operation Desert Storm illustrates a modern surprise. The product will then be analyzed in order to detect the development and how military conduct is forced to adapt in order to carry out a surprising maneuver. The results shows that the military action of performing a surprise attack has had a major development and is now carried out in a different stage of the attack..
