Planering av vägupprustning med hjälp av GIS och optimering : en fallstudie på Holmen Skog
The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district.
The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
Lean & Kaizen -dröm eller verklighet? : En kvalitativ studie med kundperspektiv i fokus
This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.
Utformning av vägen och dess omgivning : med fokus på bilförarens upplevelser
This thesis focuses on the driver?s experience of the road and its surroundings. ?The view from the road? takes place every day and a high-quality ?road experience? is therefore a question of importance. Since cars made their breakthrough in the 1920-30, the approach to ?the driver experience? has varied notably.
Användarupplevelse av ett komplext infotainmentsystem i en bil. En verklighetsbaserad studie av gränssnittet mellan människa och fordon
In recent decades here has been a huge development in information technology (IT), where we humans are increasingly using IT in our daily lives, ranging from social media to music streaming services; this has also been a reflection of the technologies developed to our cars. Infotainment systems have become an increasingly regular feature in modern cars where the high degree of integration such as navigation, mobile and Internet has become more common and more sought after. Despite this, relatively little research problemized User Experience of a complex infotainment system in a car. This study thus has the intention to consider the relevance of reality based tests by examining how the user experiences a complex infotainment system in a car. We asked ourselves; How do the user experience a complex infotainment system in a car? We conducted our qualitative study, an interview with researchers in the field of vehicle and road safety and designed a number of system-related activities in a test session where we observed three users.
Upphandling av vinterväghållning
AbstractThis report was undertaken at the request of the Management and maintenancedepartment of Swedish National Road Authority (Vägverket Region Sydöst) inJönköping.In 1992, the management and maintenance of Swedish roads were laid out onexternal contractors. When putting out a tender for the work, the foundation isfrom a national set of rules which are in constant change. This report is limited towinter road upkeep.The trend in the invitation for tenders is that it is moving from the moreconventional executional demands towards the less controlling demands. Thedownside of functional, less controlling demands is that it is difficult to articulatehow to measure them. The order authority therefore has to find ways to makesure to get what has been paid for.In connection to the invitation for tender of winter road upkeep for 2005, the newset of rules, ATB Vinter 2003 was deployed.The main purpose of this thesis is to see which the big changes in the set of rulesare and how these changes affect the organisation and activities of the contractor.It is also studied how the changes in execution is perceived by road users and howit affects the possibilities of the contractor to come as a newcomer to a new areaof administration.Interviews and examination of sets of rules has led to a list of a number ofchanges that the contractors feel affect their work in any sense.Views from road users that have come in to the order authority have beenscrutinized to see how they have experienced the change.
Utformning av sidoområden med hänsyn till vägens livscykelkostnad
Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.
Klassificering av processutrustning - en grund för riskbaserat underhåll
In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.
Systemutveckling med avseende på systemförvaltning
This final year project is dedicated to investigate the problem domain of system maintenance management. The purpose is to find problems in the system maintenance management of today. Whether there is any problem that can be elicitated in the requirements engineering?s phase that could help to obtain more maintenance management friendly systems and if it is not possible to obtain more maintenance management friendly, what else can be done?It has been learned that there are many problems today in the problem domain and the most great ones are the system documentation, stress and a systemknowledge lack among developers, system managers and system users.The requirements that have been found for this problem is good documentation, and use of simple solutions in the creating of the system..

Systemförvaltningsmodeller ? verklighetsbeskrivning eller idealiserad bild?
This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".
Giraffens blodtrycksreglering
Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.
Styrning och nödbroms av ModuLith
The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.
Simhall i Viskafors
Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.
Gabioner - Ett alternativ vid vägbanksbygge i lösa leror
The use of gabions means a reduced amount of filling material in the road section and a more narrow construction. Also the use of limestone cement columns can be reduced. All together this results in lower costs. The columns stand for about 55% of the total costs for the road. If gabions are used you can reduce the total costs with over 10%..
