Volymsrapportering vid drivningsarbete
Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.
Avvägning mellan ordersärkostnad och lagerhållningskostnad i processindustrin
Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries.The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production.
Kvalitetsbristkostnader: En kvalitetskostnadsuppföljning för produktion och eftermarknad. : En fallstudie vid Huddig AB
All companies wants? to be as profitable as possible. The company in question is one of the leaders in it´s field in Sweden. In order to increase profits as much as possible it is important to identify and eliminate eventual quality defect cost as far as possible.This study was performed in Huddig AB, and the purpose of this study is to try to develop a routine for monitoring the quality defect costs, and to improve communication and create feedback between production and aftermarket.In addition to an extensive literature review on quality defect costs most of the work have been conducted at the company. Own observations and interviews have been done with the staff to get a picture of the current situation and to try to come up with improvement proposals.During the study it was proved that much of the quality defect costs in essence, derived from the production, which is seen as positive because it is the easiest part of the company to improve.
Byggnadslogistiskt arbete för minskat slöseri ? En studie över arbetsfördelningen vid innerväggsmontage på Tuve Bygg AB:s projekt Stapelbädden etapp 3
The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.
Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm
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.
Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .
Effektivisering av ventilationsprojekt : Bravida Filial Uppsala
In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.
Första linjens chefers skattning av sina ledar- och chefsegenskaper samt strukturell empowerment före och efter utbildningsinsats för chefer inom kommunal verksamhet.
The purpose of this study was to examine whether there were any differences in how first-line managers within municipal care rated their management leadership qualities, and structural empowerment before and after the course in "leadership, learning and improvement". The study had a quasi-experimental design and 64 managers participated. There was a significant improvement in the LaMI factor ?Achievement orientation?, after participation in the course "leadership, learning and improvement". In other factors, there was no significant difference before and after training.
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
Crossbreeding in dairy cattle
The aim of this literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.
Skolutveckling med ett neurodidaktiskt perspektiv : En kvalitativ studie med skolledare, specialpedagoger och en utvecklingsledare.
AbstractThe overall purpose of this thesis was to investigate to what extent new research findings, in neuroscience and learning, may be useful in a school improvement context. In a qualitative interview study combined with questionnaire, we have investigated the approach to school improvement that exists in a municipality. Informants have been head teachers in preschool and primary school, special education teachers in a student health team and a development manager. The outcome of the study showed that all of the study participants, all of which have a formal mandated to work for school improvement occurs. It also shows that informants, according to their professional position, express different goals when relating to school improvement.
Undersökning av fosfatsbegränsningseffekter på Escherichia coli AF1000 för bättre förståelse av 3-hydroxybutyratproduktion
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Produktionsutveckling av bastuaggregatsavdelning
To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.
