AbstractThe aim of this examination paper is to get an overview on the ?no-maintenance? windowsthat exist on the Swedish market, like plastic and aluminium windows.By way of introduction the reader gets knowledge in the background and problemformulatethat this subject has. This introduction explains why it has become so popular to changeyour windows into plastic- and aluminium windows and there is an existing scepticismagainst PVC and aluminium as construction material for windows.The main part of this report is constructed by segments of interviews where bothproducers of windows and stakeholders gets to answer questions about their viewing onno-maintenance windows from a material and construction point of view and where theproduction is headed to in the future. This is followed by an evaluation of a questionnaireon how pleased the house owners that changed their old windows to no-maintenancewindows are, followed by an inspection of windows made up from wood and an aluminiumclothing, windows made from only aluminium and PVC-based windows. It ends with atheory part about the materials PVC and metal based upon facts included in literature.By reading this report you can draw the conclusion that no window can be entirely nonmaintenancebut that the materials PVC and aluminium still are good substitutes for woodto lessen the maintenance..

Benchmarking is an established method of working which is often used in order to develop the quality of the organization. However, almost 70% of the organizations with benchmarking fail due to the lack of planning and structuring of the benchmarking exercise. Maintenance sections in the paper and pulp industry are one of those who have decided to conduct benchmarking. Therefore, the purpose of this study is to gain knowledge of how the maintenance sections in the paper and pulp industry deliberately structure and plan to use benchmarking as a driving force for quality development in the maintenance sections.The study is a hermeneutic case study. Telephone interviews and document analysis have been used as data acquisition methods.The results show that there is a lack of both planning and structuring in the benchmarking process, and lack of management commitment for quality improvements within industrial maintenance.

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system.

The purpose of this thesis is to analyze and propose improvements to the current procedure for cost estimations of purchased maintenance work at Banverket, the Swedish rail administration. This governmental institution is responsible for the procurement of maintenance services for the country?s railroad network through open tenders. Due to the generally low number of contractors, it is particularly necessary to establish accurate cost estimates in order to assess the offers and ensure that a fair price is being paid to the suppliers. Several flaws associated with the current practice are identified and analyzed according to cost accounting theories.

An airline company that operates with its fleet needs to ensure that maintenance of a following and certain standard will be implemented. In this project we have sorted and divided the various working procedures of Malmö Aviation into Work Packs. These procedures are mandatory and must therefore be implemented in order to keep the aircraft airworthy at any time. Our task was to optimize and sort these working procedures by zone, panels, access and down time. We have created a maintenance program which Malmö Aviation can use and we have sorted their working procedures in B and C- Checks.Maintenance procedures that did not fit into our Work Packs have been gathered and sent back to Malmö Aviation for further inspection.This project has required a lot of extra reading in manuals and we have had a great insight into the complexity of a technical organization such as Malmö Aviation..

In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM). Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.

Examensarbetet utfördes på Priority Aero Maintenance som är belägna vid Arlanda flygplats, Stockholm. Priority Aero Maintenance är i enlighet med EASA Part 145 en godkänd underhållsorganisation och utför all sorts underhåll på ett flertal olika flygplanstyper.Underhållsarbete är ett mycket noggrant arbete som följer, av underhållsorganisationen själva, bestämda procedurer och rutiner. Hur arbetet utförs ska vara godkänt av myndigheten och finns beskrivet i underhållsorganisationens MOE, Maintenance Organisation Exposition, även kallad verkstadshandbok.Vid underhållsarbete finns det framtagna underhållskort eller jobbkort. Där varje jobbkort specificerar en särskild underhållsåtgärd. Då en underhållsorganisation åtar sig ett större underhållsarbete innebär detta således en hantering av hundratals jobbkort.Då Priority Aero Maintenance inte har en fast struktur för hur hanteringen av jobbkort ser ut, med avseende på sortering inför en underhållscheck.

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.
