Skapa ett equalized underhålls/planeringsprogram samt minimera driftstopp
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.
Anpassning och optimering av checkprogram för AW139
Presently Sjöfartsverket do their maintenance according to a standard program, which means that every maintenance task will be done when the task limit occurs. This leads to a very long downtime for the aircraft in some occasions and very short downtime in others. The goal with this work is to reach a higher regularity of the aircraft operation. To reach a higher regularity for the operational needs, this work will present a hypothetic better maintenance concept for Swedish Maritime Administration. The concept is based on equalized maintenance structure, which means that every maintenance occasions are meant to take the same time to perform.

Underhåll av underhållsarbete
The traditional view of maintenance is machine-based, where acute maintenance tasks are highly valued. Preventive maintenance is viewed as secondary and less desirable to work with. The more modern view is to regard maintenance as a process. The machine-driven tasks are still necessary but are viewed as a part of the big picture.The purpose of this study is to examine how to high light general difficulties concerning maintenance management to aid organizations to reflecting upon their own situation. The study is based upon a pilot study initiated by ProcessIT concerning relevant key figures in maintenance.

Underhållsstrategi enligt Professional Maintenance metodiken som en del av World Class Manufacturing
As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM).In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature.
Är det effektivt? : En studie av ett företag och dess förvaltning av datorbaserade system
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.
Ansvarsförhållande kring förebyggande materielvård på förbandsnivå inom armén
The change in course recently taken by the Swedish Armed Forces results in an increased use of equipment, and thereby increased requirements of preventive maintenance. This paper aims to examine the current responsibilities for preventive maintenance in an army unit. The intended effect of this examination is to disclose possible flaws, and to help make routines for preventive maintenance more effective.The questions asked in this paper are;Who, in an army unit, is responsible for the routine maintenance?When is this responsibility valid?What demands does the technical service have on responsibilities for the routine maintenance?How are these demands met?How ought to be responsible for the routine maintenance?To answer these questions the author has chosen to use a descriptive method to show the current facts. A theorizing method is chosen to, from described facts, clarify the demands of the technical service on routine maintenance.

Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter
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.

Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn
In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for Operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.
