Ersättningsmodeller för ballasttransporter : vid anläggning och underhåll av skogsbilvägar

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

Projektering av robotcell

Syftet med examensarbetet var att projektera en fysisk robotcell till Haldex i Landskrona, tillverkare av bromshävarmar, då det finns ett behov hos dem att effektivisera sin produktion för att kunna bibehålla konkurrenskraften och tillverkningen i Sverige. Bromshävarmen är en mogen produkt vilket medför att det inte skulle bli lönsamt att omforma den utan istället fokusera på tillverkningen. Därför vore lösningen att automatisera den del av monteringslinan som inte tillför något värde till slutprodukten. Robotcellen kommer att placeras på bromshävarmarnas monteringslina som en automatiserad station vilken ska utföra kvalitetskontroll av bromshävarmarna. Examensarbetet ingår i ett pågående forskningsprojekt på Mälardalens högskola inom Lean Automation, med Robotdalen och Haldex.

Vibrationsproblem i närliggande konstruktioner i samband med markarbete

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Betydelsen av öppenhet, deltagande och ansvar i utformningen av megaprojekt En analys av policyprocessen kring ESS-projektet mellan 1990-2008

This thesis consists of three parts: one normative, one empirical and one constructive, with the intention to explore the enforcement of accountability in megaprojects.The thesis aims to evaluate the level of accountability in the policy process of the European Spallation Source, ESS between 1990 and 2008. In order to make a comparison possible, a norm is created concerning how a policy process should be designed, with primary focus on openness and participation, to make enforcement of accountability possible. The policy process of the ESS is compared with this norm with the purpose of discovering whether the process contains elements that assure enforcement of accountability. After the comparison is done, it is possible to formulate constructive proposals about how the enforcement of accountability can be improved.The thesis also explores how networks, consisting of actors with particular resources, surrounding the ESS-project affects the form of the policy process, e.g. in shaping the social construction of the aim and purpose of the project.

Miljöbyggnad i ombyggnadsprocessen : Miljöcertifiering av Jakobsbergsskolan i Kristinehamn

Climate change is an increasingly widely known concept. In the EU the construction sector is responsible for more than a third of the carbon dioxide emissions and 40 % of the total energy use. In Sweden, measures have been taken to prevent this climate change. By 16 targets, three of which can be linked to the construction sector, Sweden will reduce the negative trend. None of the three goals with relation to the construction sector will however be achieved before 2020.

Lean i Primärvården.

Miljön på en intensivvårdsavdelning är utformad för att vårda kritiskt sjuka patienter med livshotande skador. Rummet är fyllt med högteknologisk apparatur, höga ljud, ofta flera patienter på samma sal och personal som ständigt närvarar i rummet. Närstående har en stor betydelse för patienten och de har behov av att få vara nära, få information och känna delaktighet när deras anhörige är svårt kritiskt sjuk. Intensivvårdsmiljöns påverkan på den närståendes besök är viktigt att lyfta fram för att kunna möta närståendes önskan att vara nära samt skapa en vårdande miljö där både patientens och närståendes behov beaktas. Syftet med studien var att undersöka närståendes upplevelser av att besöka en anhörig i intensivvårdsmiljön.

Resurssnåla materialflöden - En fallstudie på Volvo Powertrain

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

Analys samt förslag till effektivsering av patientflödet vid en vårdcentral

In the year of 2009 the conditions for managing primary healthcare in the region of Västra Götalandchanged. The decision was taken by the regional assembly and resulted in that the citizens since thenhave had the opportunity to choose which health care provider they preferto stay with. Along with thisdecision a new market for private health careproviders was established, which resulted inincreasedcompetition between the providers.In order to manage the competition, the health care providers arenow forced to be more efficient in their operations andalso to beeven more focused on their patients.Backa Läkarhusgruppen is an example of a private healthcare provider in the region of Västra Götaland.In the same way it is also an example of anorganizationin need of analysing their operations to seehowit can be further optimized to meet patient needs and expectations.The aim of this study is to analyse Backa Läkarhusgruppen?s organization and its operationsin the hopeoffinding suggestions whichwill improve the patient flow.To allocate and solve the problems thatBacka Läkarhus suffer from,an approach inspired by Lean Healthcare is used throughout the report.Some of themost significant problems that were identified within the organization are:?The synchronization of demand and capacity is inadequate.?Absence of standardized routines.?Absence of present leadership.To be able to improve the patient flow Backa Läkarhus needs to handle these identified problem areas.By synchronizing the staffing level in relation to the trends in demand a reduction in the patient?swaiting times and throughput time will be possible. Creating clear responsibilities and routines for thestaff will contribute to a higher degree of patient focus and thus lead to a more efficient patient flow.

Konstruktionen av företagare som diskursiva subjekt : en diskursanalytisk studie av hur kvinnor och män representeras som företagare i tidningen Eget Företag

Given the possibility that the world, as we know it, is a consequence of human interaction and verbal communication our understanding of the world can be seen as contingent rather than essentially given. Conceptions such as "entrepreneur", "woman" and "man" can then be understood as socially constructed subjects. Departing from poststructural and social constructionist perspectives I will examine medial representation of women and men as entrepreneurs. My main purpose is to examine how the entrepreneur is constructed as a discursive subject in the journal Eget Företag. Drawing upon Ernesto Laclau´s and Chantal Mouffe´s Discourse Theory and the poststructuralist feminist theoretical perspective of Judith Butler I will discuss both the construction of the entrepreneur as well as the more explicit question; is gender significant for the construction of the entrepreneur and entrepreneurship in Eget Företag? In this study I come to the conclusion that the discourse of entrepreneurship, as well as the journalistic discourse, draws upon discourses of femininity and masculinity but also upon discourses of ethnicity.

En kvalitativ studie om hur chefer i socialt arbete ser på sitt ledarskap

The aim of this study was; from a group of boys and girls description and interpretation of interaction with other young people, personnel and the environment of the youth centre illuminate how the social gender are constructed and maintained at the youth centre. In this study we have tried to analyse the phenomena from an intersectionalistic perspective. Except gender, the analytic category social class have been tried to capture. Our theoretical standing point is social constructivism. Institutionalized structures in our society are constructed by humans, gender is not only a biological construction it is also a man created construction.

Det innebär en ökning med cirka 36 procent jämfört med produktionen 2004. Syftet med detta examensarbete är att verifiera och prioritera parametrar som påverkar sågens effektivitet, samt att ta fram en åtgärdsplanering för att nå en produktionsökning med 36 procent till 2009.

Problemrepresentationen av arbetslöshet och arbetslösa : En diskursanalys om problematiseringen av arbetslöshet och arbetslösa i nationella policydokument åren 1979/80 och 2006/07

This essay is about the problematization of uneployment and unemployed in national policy documents of the years 1979 and 2007. The purpose of this essay is to illustrate and analyze the problematization of unemployment as a construction. My overall aim is investigating how the unemployed and unemployment are represented and constructed in the Swedish political debate the years of 1979/80 and 2006/07 by analyzing national policy document. The analysis will consist of questions about the problemrepresentaion made by unemployment and the unemployed, the assumptions behind this problematization and what kind of impact it could generate for the unemployed.  In this way, the study aims to investigate the changes that may have occurred in how unemployment is problematized in the Swedish policy documents and highlight citizenship conditions on the basis of labor market policy.

Styrdokument för kontorsbyggnation ur ett ekologiskt hållbarhetsperspektiv : Aspekter och argument

The construction and real estate industry represents a significant part of Sweden's total impact on the environment and mainly affects the following national environmental objectives: reduced climate impact, a good built environment and a non-toxic environment. By establishing internal rules, companies within the industry can reduce their environmental impact. SMT (AB Sandvik Materials Technology), a part of the industrial group Sandvik AB, has set a target that during 2014 develop a guiding document with special consider to the environmental impact during construction of office buildings, that they establish at the Swedish regional capital Sandviken, for both internal and external tenants. This study therefore aims to clarify which environmental aspects that the construction and real estate sector mainly are responsible for, and therefore should be part of a guiding document for a company for establishing office buildings, and to present arguments regarding the use of such a document. The study is based on literature studies and personal contact with other companies, in the form of e-mail conversations and a telephone interview.
