Ur led är tiden: En studie av metoder att korta ledtider inom forskning och utveckling

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening lead times and how these methods effect the lead times in research and development.

Behovet av blyhandskar som skydd mot sekundärstrålning vid röntgenundersökning av djur

X-rays are a potential risk for animal health care personnel. The present study will examine the risks for scattered radiation to the personnel, if no lead gloves are used when holding an animal during the x-ray examination. Furthermore, how the impact of the exposure values and body parts examined, affect the scattered dose to the hands of the holder. Also, the distance between the animal and the hand that holds it was evaluated to see the impact on scattered radiation exposure. Tested by a survey, to animal health care students, the frequency of the usage of lead gloves in Swedish animal hospitals was studied. According to the results from the analysis, animal health care personnel don't need to use lead gloves every time they hold an animal or a cassette during x-ray examinations.

Utveckling av processparametrar inom en hårdmetallindustri

This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

Reducering av ledtid genom en värdeflödesanalys En fallstudie på Lammhults Möbel AB

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

Att se sig själv som en del i ett större perspektiv : En analys av skolämnet historia i Lgr 69, Lgr 80 och Lpo 94.

In this essay, I intent to examine history as a school subject in Swedish compulsory school (for children aged 7-16), it contains mostly an analysis of the syllabus for history in the three latest curriculums Lgr 69, Lgr 80 and Lpo 94. The main purpose of the essay is to illuminate the development and the change history as a subject has gone through during this specific time, and my will is also to illustrate the view on knowledge and learning that is revealed in the syllabus for history in today?s curriculum (Lpo 94).The survey shows that in Swedish compulsory school, history as a subject has changed significantly. During the examined years, the contents have been exceptionally broadened and that has lead to increasing demands on the students as it has gone from being directed to the individual and its contiguous history with shorter outlooks on the rest of the world, to requiring the individual to be able to see and understand other parts of the world and different time, on the basis of it?s own history and culture.

Emotionella upplevelser och emotionsreglering i samband med en nedskärningsprocess

The aim of this study was to investigate emotions and emotion regulation of a downsizing in an industrial company. The sample consisted of persons who had experienced a downsizing but have kept the employment, within a same position or being transferred to another one. Data consisted of two focus group interviews, analysed by an inductive thematic analysis. The results have indicated that emotional reactions changed over time as well the emotional regulation did during the different phases. The groups differed in emotional reaction related to the time of decision regarding the retention of employment.

Simulation driven design : An iterative approach for mechanical engineers with focus on static analysis

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Väntetidsrelaterad frustration på akutmottagningen

Aim: The aim of this study was to describe what nurses experienced in connection with waiting time related frustration among patients and relatives in the emergency department and also what strategies nurses use to manage waiting time related frustration.Background: The numbers of emergency department visits are increasing and lead to waiting times which can cause frustration among patients and relatives, a frustration that nurses encounter in their everyday work and need strategies to deal with.Methods: This is a descriptive qualitative study. Interviews are conducted with five nurses, transcribed and analyzed by qualitative content analysis.Findings: The nurses feel inadequate and powerless when they meet patients and relatives frustration. In order to deal with patients and relatives frustration, they use the strategy of participation, which implies to involve and meet patients and relatives needs for information and to be seen. In order to prevent themselves becoming frustrated they use adaptability, by creating an inner calm, not take it personally and to distance themselves from the frustration.Conclusion: The result highlights the importance of managing the activity to reduce waiting time related frustration, for example through reflection and working for reducing waiting times. Further research is also needed..

Värdekedjeanalys av returflöden på Scania : Fallstudie på marknaderna i Sverige, Tyskland och Benelux

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Naturen och trädgårdens betydelse för återhämtning vid utmattningssyndrom - kvinnors berättelser :

Nature and garden have always had meaning in human's life and succesfully seen as having health giving effects. Health is a state of equilibrium between physical, psychological, social and spiritual well-being. The individual's health is depending of how the society looks and how the individual manages to live her life in it. Stress is one of our time's large public health problems and leads in some cases to burned out syndrome. Stay in nature gives recovery according to theories of environmental psychology.

In this work a research had to be done to show how the material supply system looks like today and to explore the subframe components to see which components that are interesting from Kanban viewpoint. Previous orders of subframes were investigated. Therefore, it was a list of the various components of the previous orders for the subframe.

Medborgardialog i ortsanalys : ett arbete om värdet av kommunikation tidigt i planeringsskedet

Citizen participation is fundamental in place analysis, where the aim is to define the sites specific character and identity. The local citizens know the village better than anyone else since they lead their daily life in the environment. I have in cooperation with Sala municipality suggested guidelines on how to involve the local people in dialogue during place analysis. The target was to involve and enthuse as many people as possible with relatively small resources in time and money. The suggested methodology was tried out in a place analysis of Västerfärnebo, a community with about 3 000 inhabitants of which 500 live in the main village.
