Det vore ju skam om det inte fungerade bättre ? En fallstudie förfelsökning av projekteringsprocessen

Den här rapporten redovisar resultatet av en fallstudie på projektet Göingegården som genomförs iregi av Derome Mark & Bostad. Syftet med rapporten är att kartlägga arbetsprocessen och därefterbelysa var det finns felkällor och störst förbättringsmöjligheter, av vilken anledning samt vilkakonsekvenser som dessa får. Rapporten belyser och åskådliggör vilka åtgärder och lösningar som böranvändas och dessa åtgärder utvärderas ur ett LEAN perspektiv med fokus på tid och kostnad someffekter.För att kunna nå dit har en stor del av arbetet inriktats sig mot att förstå hur processen fungerar, hurarbetet ser ut på Derome samt synliggöra vilka avvikningar som finns och hur dessa utspelar sig i detlånga loppet. Arbetet med eftersökning och felsökning består av främst av möten, intervjuer ocheftersökningar om hur arbetet sker på andra företag i samma bransch.Dessa avvikelser analyserades och deras härkomst, varför de uppkommer, undersöktes och fokus lågpå att hitta förbättringspunkter som är återkommande och inte bara engångsproblem. Attgrundstenarna och visionerna som finns i LEAN är tätt sammanknutna med de åtgärdsförslag somredovisas i rapporten ser vi som en klar utgångspunkt.Resultatet av rapporten visar på att inom projekteringsdelen av projektet finns det brister och deflesta av dessa brister härleds komma från omodern teknik.

Lean inom sjukvåren : Effektivisering av patientflöde

This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules.

DEN EKONOMISKA EFFEKTEN AV ÖVERKLAGANDEN I GÖTEBORG - Kan överklaganden mot bostadsbyggnadsprojekt härledas till demografiska faktorer och vilka ekonomiska effekter kan de ge för byggföretagen?

This bachelor thesis addresses the problem of appeals against house building in Gothenburg. The thesis investigates whether there is a statistically significant relationship between demographic factors and the occurrence of approved, appealed and revoked permits for new construction of residential buildings in the ten districts of Gothenburg. This is done with a correlation analysis. The report also investigates whether there is a statistically significant regression in the same demographic factors and how these individually affect the average processing time for appeals in the districts. This study is done with a multiple regression analysis.

Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Lean Logistics: Implementering av Lean och Supply Chain Management i svensk industri

Vårt moderna samhälle är idag beroende av dagliga transporter som både är en stor kostnad för producerande företag och dessutom har en stor miljöpåverkan. Främst eftersom klimatfrågan idag debatteras flitigt men också för att det finns stora incitament för företagen att minska sina transportkostnader kommer vi, med största sannolikhet att se stora effektiviseringar av denna bransch inom en snar framtid. I detta arbete behandlas därför i vilken utsträckning två välkända teorier, Lean och Supply Chain Management, kan användas för att optimera transporterna främst vad gäller kostnad och miljöpåverkan. Efter att ha analyserat ett flertal rapporter som behandlat dagens transporter, transporttyper av olika slag och pågående miljöregleringar samt intervjuer med två svenska industribolag har vi kommit fram till att dessa två teorier inte lämpar sig i alla situationer. Lönsamheten i användandet av dessa två teorier beror på vilken teknisk grad företagets produkter har samt hur stor företagens produktion är.

Sustainable Construction in the Transportation Infrastructure Industry? as a vision and in practice

This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.

Hur och varför media konstruerar ledarskap - Ett kliv in på redaktionen för att utvärdera tänkbara förklaringsmekanismer

In modern leadership research, leadership is often viewed as a social construction, and under this paradigm various researchers let the media play a central role in constructing leadership. Meanwhile, the question of how the media actors do this is left unanswered. We explore the question of how and why the media construct leadership, from the vantage point of the media actors themselves, and the conditions they work under. Different mechanisms for media construction of leadership are identified in previous research. Through interviews with business journalists at Veckans Affärer, we find recognition for some of the explanatory mechanisms: namely that personification of a CEO facilitates the work of journalists (and sells papers), that personal drama captures reader demand, and that the CEO of a listed company consciously cultivates his or her personal parallel self.

Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Anläggningsmätning

This report aims at giving you as a reader a basic knowledge in measurement techniques used in the road/land construction and witch instrument and methods that is commonly used. It also tries to shed light on the problem with unfinished or incomplete blueprints, which cause additional work performed by the surveyor. This report is written in collaboration with PEAB Umeå whom has given insight in their work.The goal of this report is to examine what kind of work surveyors has to perform on blueprints delivered by a technical consultant. The reader of this report gets a run-through of the different theoretical measurement techniques used today and a short explanation of different measuring instruments used by surveyors in their day to day work. Computer programs used in the field of construction are briefly explained, and some of the most common file extensions used, for example dwg and Land-xml.The report concludes in a questionnaire that was sent out to surveyors employed by PEAB.

Erfarenhetsåterföring i Sveriges två ledande byggbolag : Riktlinjer, utfall och konsekvenser

The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.

Produktionseffektivisering : - Få processens samtliga aktörer att sträva mot samma mål genom ökat samarbete och delaktighet i produktionens olika skeenden.

The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.

Diskrimineringsersättningen och dess avskräckande verkan : Förarbeten och praxis ur ett arbetsrättsligt perspektiv

The aim of this study was to give an insight of the construction of girls in their relationships with friends and lovers in the Swedish magazine Julia. The magazine turns to girls of age nine to fourteen. The research questions were 1) What is the construction of the girls in their relationships with friends and lovers about in Julia? 2) How are girls constructed in their relationships with friends and lovers? Three issues of the magazine from the winter of 2014 were selected as material for the study. Critical discourse analysis (Fairclough, 1992, 2010) was the point of departure in the analysis.

Effektivisering av en produktionslinje för designade trägolv vid Kährs

AB Gustaf Kährs grundades 1857 i Nybro och 1947 blev Kährs först med att få patent på ett trägolv. Enligt Kährs är deras affärsidé att erbjuda miljövänliga och högkvalitativa trägolv för privata, offentliga och kommersiella miljöer. Under de senare åren har marknaden för robustare och mer formgivna trägolv vuxit. Därför har Kährs på kort tid byggt upp en ny linje för designprodukter. Det finns ett behov av att utvärdera och analysera linjen ur ett produktionstekniskt perspektiv med hjälp av olika LEAN verktyg.

Avfall på byggarbetsplatsen : statistik som hjälper platschefen

The purpose of this report is to find a model of statistics for construction and demolition waste, which makes it useful for the local manager at the building site. The intention with the model is that it will be used as a support of the local manager, to direct his project towards reduced strain of the environment. The model will also be used to make it easier to control that the claims from authority and aims for the environment are achieved. To familiarise with the subject waste handling within the building and construction sectorI have done a literature search. I have also been studying rules and regulations regarding the waste handling.

Från knackningar till blodspår - Analys av Marie Hermansons Mannen under trappan

This essay examines the differences and similarities, weaknesses and strengths of the two Cognitive Semantic theories Conceptual Metaphor Theory and Principled Polysemy Approach to Meaning Analysis. To illustrate the two theories, the Swedish verb-particle construction "gå upp" is examined and analyzed accordingly. The results showed differences in the number of polysemous meaning found. The methodological evaluation showed that the differences in the underlying ideas concerning meaning-construction behind these two theories make them incompatible..
