This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Detta examensarbete utfördes på Saab AB, Support & Service, i Tannefors, Linköping, samt vid Institutionen för datavetenskap på Linköpings universitet. Ett moment i kvalitetsarbetet för komplexa industriprodukter, som till exempel flygplan, är att skifta från tvådimensionellt konstruktionsunderlag till tredimensionellt. Tredimensionella modeller har funnits i flera år. Nackdelen med dessa modeller är att de inte kunnat bära någon extra information, förutom den information som krävs för att de ska vara uppritade. Tekniken har gått framåt och nu går det att lagra teknikinformation i modellerna samt göra simuleringar som inte gått att göra förut.

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

This essay contains material of how the competence maintenance works on a chosen company and how a web based tool developed for its use can help companies with competence insur-ance. As competence maintenance is a major factor to have a long term profit it´s necessary to be aware of the company?s future needs in the competence sector. This essay describes the company?s competence maintenance occupation needs taken from internal documents; it also identifies the need for competence maintenance and presents multiple areas of possible im-provements.

Background: The standard of living should be the same for everyone, whether the apartment is placed in an old or new building. The residential properties that were built from 1965 until 1974 is now beginning to become old and in need of restoration. The financial crisis during the nineties contributed to the lack of maintenance on the buildings in Sweden. As the public buildings gets older more and more defects occurs. The coordination and maintenance will therefore have a more significant role in the housing company ?s work.The increasing interest about how old a building can be, attract much attention.

This report is a thesis on requests from Sandvik Mining and Construction (SMC) in autumn of 2012. The goal of this work was to study the feasibility of creating and implementing an Equalized preventive maintenance program in SMC maintenance operations and reduce downtime for preventive maintenance (PM). To investigate whether this was possible, the authors studied the current procedures for the PM. The authors have collected and analyzed all relevant information within the maintenance department reporting system as well as through interviews determined whether it is practical to introduce a Equalized PM programs. The authors had also studied the possibilities to entrust part of the maintenance work to the operators of the machine cells.

The SK 60 Aircraft has been a workhorse for the Air Force?s training of future pilots since the late 1960s. The aging SK60 aircraft is going out of style, and the system has merely a few years of total running time left. A replacement for the SK 60 needs to be implemented in the coming years, and the Armes Forces Flying School has been commissioned to conduct flight tests on suitable replacement systems. This study will conduct a system analysis of two aircrafts mentioned in the Flying Schools report.

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..

The purpose with this article is to give examples how to remain and in a long run develop a higher interest in maintenance activities and knowledge. First reason is the changed age-distribution with more number of older employees among maintenance personnel staff and second reason is demand for education due the increasing demand in environmental responsibility.In spite of there is a lot of knowledge of maintenance in national organizations of interests it will not be used in a sufficient extent in many companies. This knowledge is an important base to use to re-built the missing or loosed skills in companies. The national organization UTEK is involved in European projects to validate knowledge of maintenance. Lost of or bad maintenance activities will always affect on the environment.Establish a network between companies is a good way to exchange information in their common business areas.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

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.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.

This diploma work handles how some parishes of the Swedish Church administrate their building properties.The report also includes how some external property managers in Sweden work with maintenance plans and other maintenance issues. Further, a number of deficiencies have been identified and suggestions to workarounds are treated. The conclusions drawn in this thesis are based on the author´s experience in the field, performed interviews, and literature studies. The result of the work shows a general lack of knowledge in many parishes what concerns regulatory requirements, properties with no maintenance plan and substandard supervision resulting in unnecessary and expensive repairs. Based on these results, different plans for the maintenance of the building properties of the Swedish Church has been proposed..
