Research on Customer¡¦s Environment Strategy and Supplier¡¦s Environmental commitment in automobile industry.Wu, Shu-Chin 31 May 2012 (has links)
The Green factory mark system validated by the Ministry of Economic Affairs will be officially launched in 2012. The assessment of green plants covers not only in the prohibition of harmful substances during the manufacturing process, reduction of unnecessary waste and promotion of environmental protection policies, but also extends to the whole supply chain from raw materials, parts suppliers to proceed with the environmental protection policies, and ultimately helps to achieve the objective of the green supply chain. However, there are no related laws to require part suppliers to adhere to green production plant objective currently in car industry. This study focuses on how customers affect and influence suppliers¡¦ environmental commitment based on its own environmental strategies and environmental performance requirements.
The study is mainly from the constructs of customer¡¦s environmental strategy and customer¡¦s environmental performance requirements which includes moderators of contract, evaluation, and encouragement to investgae the relationship with suppliers environmental commitment. The study takes 246 suppliers of Honda Taiwan Motor Co., Ltd as sampling and utilizes Likert five-level scaling method from 1 to 5, from ¡uStrongly disagree¡v¡B¡uDisagree¡v¡B¡uNeither agree nor disagree¡v¡B¡uAgree¡v¡B¡uStrongly agree¡vto confirm hypothesises of the study.
According to the results of this study, the predictive factors for improving suppliers¡¦s environmental commitment are customer environmental performance requirements; customer environmental strategy and contract in order. The statistical results are significant. In other words, suppliers will raise its environmental commitment according to its major customers¡¦ environmental performance requirements and environmental strategies. Suppliers also agree that contract restrictions signed with major customers would enhance and raise its environmental commitment. The study takes Honda Taiwan Motor Co., Ltd. as an example trying to see how to raise suppliers¡¦ environmental commitment without any laws reinforcement and expects to set the standard for other companies in Taiwan.

Development of Quality Assurance Methods for Performance-Based Maintenance Contracts for Roadway AssetsShelton, Debora Brooke 2010 December 1900 (has links)
Performance-based Maintenance Contracts (PBMCs) are increasingly being used for
roadway maintenance as an alternative to method-based specifications. However, this
technique is still relatively new and several issues have not been adequately addressed in
the literature. The paper provides a systematic process for developing quality assurance
measures to be used within these contracts. The process addresses key issues, including
the development of performance standards and targets, a method for monitoring the
roadside performance, and a methodology for developing pay adjustment factors.
The developed performance standards presented in the paper are easily measured and
assigned grades of pass, fail, or not applicable. The required sample size is a function of
the project characteristics, including performance variability along the project, required
confidence level, and allowable tolerance. Finally, the pay adjustment curves are a
function of the initial project LOS, the target LOS, and the maintenance cost to achieve
the target LOS.

Dagens inneklimat : En granskning av svenska riktlinjer för rådande inneklimat / Indoor climate today : A review of the Swedish guidelines for the prevailing indoor climateBenitez, Miguel, Goyeryd, Adam January 2015 (has links)
I dag pratas det mycket om hur viktigt det är med ett bra och hälsosamt inneklimat. För att människor ska trivas och arbeta effektivt behöver arbetsplatsen ha ett bra inomhusklimat. Eftersom människan spenderar största delen av sitt liv inomhus är det viktigt att inte påverkas negativt av den inre miljön. Byggnadens huvudsyften är att skydda människor men många byggnader orsakar hälsoproblem av olika slag. Det finns mycket liten vetskap om vad ett bra inneklimat verkligen innebär. Detta kan till exempel orsaka kommunikationsproblem som försvårar förhandling då kunden och företaget tolkar varandras åsikter om inneklimat olika. Syftet med examensarbetet är att underlätta förhandlingsprocessen genom att definiera innebörden av inneklimat samt beteckningar som vanligen används. Detta ska hjälpa både kunden och företaget att förstå vad kraven och riktlinjerna betyder genom att utgå från gemensamma definitioner och förutsättningar. Arbetet har utförts utifrån allmänna definitioner av inneklimatfaktorer samt beskrivningar av riktlinjer. Problematiken, som uppstår vid överenskommelse med kunder på grund av saknande av information, har identifierats i samtal med experter. Definitionerna och beskrivningar som tagits fram i rapporten kommer att användas för att hjälpa till under förhandlingar och underlätta kommunikationen mellan beställare och utförare. Arbetet har lett till några slutsatser som är värda att tänka på: Bristen på kunskap kan försvåra förhandlingar, därför är det viktigt att informationen förmedlas på ett tydligt och pedagogisk sätt. Riktlinjerna är där som stöd vid projektering eller bedömning, men de bör behandlas med viss försiktighet på grund av den begränsade uppdateringen av dessa. / An actual question is the importance of having a good and healthy indoor climate. The workplace need to have a good indoor climate, so that people can thrive and work effectively. Since people spend most of thier lives indoors, it is important to avoid being negatively affected by the internal environment. Buildings have the main purpose to protect people but many buildings cause health problems of various kinds. There is a poor knowledge of what a good indoor climate really mean is. This can, for example, cause communication problems that complicate the negotiation where the customer and the company have different concepts of what indoor climate is. The purpose of this project is to ease the negotiation process by defining the meaning of the indoor climate and commonly used terms. This will help the customer and the company to understand the meaning of requirements and guidelines by starting from common definitions and conditions. This project has been written based on general definitions of the factors that affect the indoor climate as well as descriptions of the guidelines. The problem that emerges in agreement with the customers, because of lacking information, has been identified in discussions with experts. Definitions and descriptions contained in this essay will be used to assist during the negotiations and ease the communication between the client and contractor. The project has led to some conclusions that are worth thinking about: The lack of knowledge can aggravate negotiations; therefore it is important that the information is mediated in a clear and educational way. The guidelines are there to assist the planning or assessment, but they should be treated with caution because of the limited update of these.

Kan kreativitet manipuleras? : En experimentell studie om hur prestationskrav under tidspress påverkar kreativiteten / Can creativity be manipulated? : An experimental study on how performance requirements during explicit time constraint affect creativityAgestad, Emma, Lindgren, Mia January 2017 (has links)
Kreativitet är ett populärt begrepp som frekvent förekommer i arbetslivet. Trots begreppets popularitet varierar förutsättningar till att vara kreativ mellan arbetsplatser, och många medarbetare upplever att de inte får utlopp för sin kreativitet i sin arbetsroll. Den föreliggande studiens syfte låg därmed i att undersöka hur olika förutsättningar kan påverka kreativiteten. De två frågeställningar som besvarades var: a) Kan individers kreativa prestation manipuleras av prestationskrav under uttalad tidspress? b) Kan individers självskattade kreativitet manipuleras av prestationskrav under uttalad tidspress? En experimentell studie utfördes med totalt 89 deltagare randomiserat fördelade i två grupper. Experimentgrupp 1 hade totalt 47 deltagare, varav 23 kvinnor (48.9%) och Experimentgrupp 2 hade totalt 42 deltagare, varav 15 kvinnor (35.7%). Experimenten genomfördes individuellt och enskilt med en deltagare åt gången. De mätinstrument som användes var Guilfords (1967) Alternative Uses Task för att mäta kreativitet och Mini-IPIP6 för att även kontrollera för personlighetsdrag. Det aktuella föremålet i Alternative Uses Task var en kaffemugg som deltagarna skulle komma på alternativa användningsområden till. Experimentgrupp 1 fick ett prestationskrav att komma på minst 15 alternativ samt uttalad tidspress. Experimentgrupp 2 utförde samma kreativa uppgift, men hade inget prestationskrav och ingen uttalad tidspress. Data analyserades med hjälp av IBM SPSS och de analysverktyg som användes var Pearsons korrelation (r), oberoende t-test och Repeated Measures ANOVA. Resultaten visade 1) att Experimentgrupp 1 producerade fler kreativa idéer än Experimentgrupp 2, men att Experimentgrupp 2 hade signifikant högre kreativ kvalitet på sina idéer än Experimentgrupp 1. Vidare visade resultaten 2) att manipulationen inte hade en signifikant effekt på den självskattade kreativiteten när personlighetsdraget Openness kontrollerades för. / Creativity is a popular term that frequently occurs in the working life. Despite its popularity, the possibility to be creative varies a lot between work places, and many employees feel that they do not have a creative outlet in their work role. The purpose of the present study was to examine how different conditions could affect creativity. The two questions that this study intended to answer was: a) Can individuals' creative performance be manipulated by performance requirements during explicit time constraint? b) Can individuals' self-rated creativity be manipulated by performance requirements during explicit time constraint? An experimental study was conducted with a total of 89 participants randomly distributed into two groups. Experimental group 1 had a total of 47 participants, of which 23 women (48.9%) and Experimental group 2 had a total of 42 participants, of which 15 women (35.7%). The experiments were conducted individually with one participant at a time. The measuring instruments used were Guilford's (1967) Alternative Uses Task to measure creativity and Mini-IPIP6 to control for personality. The current item used in Alternative Uses Task was a coffee mug that the participants were assigned to write down as many alternative uses for as possible. Experimental group 1 had a performance requirement to write down a minimum of 15 alternative uses and an explicit time constraint. Experimental group 2 did the same task, but without performance requirement and no explicit time constraint. The collected data was analysed with IBM SPSS and the tools used for the analyses was Pearson's correlation (r), independent t-test and Repeated Measures ANOVA. The results showed a) that Experimental group 1 produced a higher number of creative ideas than Experimental group 2, but that Experimental group 2 had a significantly higher creative quality on their ideas than Experimental group 1. Further the results showed b) that it was not possible to manipulate the self-rated creativity when the personality trait Openness was controlled for.

Hur påverkas studenters upplevelser och hantering av stress av personlighet? / How are students’ experiences and coping with stress affected by personality?Johansson, Linnéa, Dzirlo, Sabina January 2020 (has links)
Studenter tolkar och hanterar upplevelser och problem olika. Något som kan påverka studenters tolkningar och hantering är deras personlighet. Syftet med studien är att undersöka studenter vid Örebro universitets upplevelser av stress, i form av allmän stress och prestationskrav, och socialt stöd, i relation till benägenhet till olika copingstrategier. Vidare är syftet att undersöka om personlighetsdimensioner från femfaktorteorin är en bidragande faktor till studenternas skilda upplevelser. Data samlades in genom enkäter som publicerades på sociala medier och fanns tillgängliga för studenterna. Totalt 226 studenter svarade på enkäten. Enkäten bestod av frågor från etablerade mätinstrument. Resultatet visar att studenterna upplever måttlig stress och mycket socialt stöd. Studenterna var mer benägna att använda copingstrategier vid låga prestationskrav samt lågt socialt stöd. Studenternas upplevelser av allmän stress, prestationskrav samt socialt stöd och benägenhet till användning av copingstrategier påverkas delvis av de olika personlighetsdimensionerna. Slutsatsen är att personlighetsdimensioner från femfaktorteorin är delvis en anledning till studenters skilda upplevelser och hantering av stress. / Students interpret and handle experiences and problems differently. Something that can affect students’ interpretations and management is personality. The study’s purpose is to examine students at Örebro University interpretations of stress, both general stress and performance requirements, and social support, in relationship to coping strategies. Further, the purpose is to see if personality dimensions from five-factor theory affect students’ experiences of stress in relation with coping strategy. Data were collected through surveys that were published on social media for the students, and consists of questions from established measuring instruments. 226 students answered the questionnaire. Results showed that students experience average stress, and high social support, and tend to use coping strategies for low performance requirements and low social support. Personality dimensions from the five-factor theory partly affect the interprets of general stress, performance requirements and social support, and tendencies of using coping strategies. The conclusion is that personality dimensions from five-factor theory is partly a reason why students’ interpretations and stress management differ.

FÖRFRÅGNINGSUNDERLAG-TOTALENTREPRENAD : BYGGNATION AV DUBBELSPÅRFUNKTION GODSSTRÅKET HALLSBERG- DEGERÖN DELEN STENKUMLA-DUNSJÖMofti, Wirya January 2014 (has links)
Turnkey contract is a commonly used form of contract for procurement of projects, however not so common when it comes to rail infrastructure, because railway installations are so complex and makes greater demands on availability and traffic safety. Performance contracts have occurred in railway projects for a long time. The Swedish Transport Administration has received directives from the government to push for increased productivity and increased degree of innovation in the construction industry. The Swedish Transport Administration has the ambition to transform its role as a client to create the conditions for the market and its driving forces for increased innovation and productivity by handing over a greater commitment and responsibility to the contractors. A strategic primary focus is to increase the proportion of turnkey projects within the construction industry. Contracts relating to investments between 25-500 million will be procured through turnkey projects. The purpose of this report is to identify how the market views the specifications with emphasis on object-specific technical description, its calculability, structure and clarity. The section that has been analyzed in this report is the construction of the freight line between Stenkumla - Dunsjö that is part of the whole distance between Hallsberg - Degerön. Interviews were conducted with entrepreneurs who have participated in the bidding contest. The purpose of the interviews was to get the contractors' views on the specifications that can be taken into account in future projects. Responses will be analyzed by the Swedish Transport Administration and taken into account for the development of future specifications in turnkey contracts for the construction industry. OTB for the route Stenkumla - Dunsjö, entrepreneurs are not allowed to come up with innovative solutions, since the specifications contain many technical solutions specified by the Swedish Transport Administration. The contractors want more freedom in the specifications in order to provide innovative solutions. One reason that there are many technical solutions in this project is because, the project was meant to be procured as performance contract and Traffic Authority had already planned a lot before they decided to purchase it as Turnkey contract. / Totalentreprenader är vanligt förekommande entreprenadformen vid upphandling av projekt dock inte så vanligt när det gäller järnvägsanläggningar eftersom järnvägsanläggningar är så komplexa och ställer större krav på tillgänglighet och trafiksäkerhet. Utförandeentreprenader har varit entreprenadformen som har förekommit vid järnvägsprojekt under en längre tid. Trafikverket har fått direktiv från regering att verka för ökad produktivitet och ökad innovationsgrad i anläggningsbranschen. Trafikverket har som ambition att förändra sin roll som beställare för att skapa förutsättningar för marknaden och dess drivkrafter till ökas innovation och produktivitet genom att överlämna ett större åtagande och ansvar till entreprenörerna. En strategisk huvudinriktning är att öka andelen totalentreprenader inom anläggningsbranschen. Entreprenader som avser investeringar mellan 25 – 500 Mkr ska 50 % av entreprenaderna upphandlas genom totalentreprenader. Syftet med denna rapport är att kartlägga hur marknaden ser på förfrågningsunderlaget med tonvikt på det objektspcifik tekniska beskrivningen, dess kalkylbarhet, struktur och tydlighet. Sträckan som har i denna rapport analyserat är byggnationen av godsstråket mellan Stenkumla – Dunsjö som är en del av hela sträckan mellan Hallsberg – Degerön. Intervjuer har utförts med entreprenörerna som har deltagit i anbudstävlingen. Syftet med intervjuerna har varit för att få entreprenörernas synpunkter på förfrågningsunderlaget som kan tas hänsyn till i kommande projekt. Svaren kommer analyseras av Trafikverket och tas i hänsyn till utvecklingsarbetet av framtida förfrågningsunderlag inom totalentreprenader för anläggningsbranschen. OTB för just sträckan Stenkumla – Dunsjö, tillåts inte entreprenörerna komma med innovativa lösningar eftersom förfrågningsunderlaget innehåller många tekniska lösningar som angivits av Trafikverket. Entreprenörerna vill ha mer frihet i förfrågningsunderlagen för att kunna bidra med innovativa lösningar. En anledning till att det finns många tekniska lösningar i detta projekt är att det finns en beslutad järnvägsplan. Järnvägsplanen styr utformningen av anläggningen.

Identificação de requisitos de desempenho de sistemas de proteção periférica (SPP) em obras de edificações / Identification of performance requirements for temporary edge protection systems for buildingsPeñaloza, Guillermina Andrea January 2015 (has links)
Na indústria da construção, as quedas de altura constituem-se em um dos tipos mais frequentes de acidentes graves. Alguns fatores contribuem para essas quedas, entre os quais se destacam a falta de qualificação dos trabalhadores, restrições de leiaute e a falta de barreiras de proteção contra quedas. Embora o uso de sistemas temporários de proteção periférica (SPP) seja uma medida importante para prevenir as quedas de altura em canteiros de obras, a literatura não apresenta um conjunto abrangente de requisitos para esses sistemas. As normas de segurança e saúde no trabalho na construção civil, tanto no Brasil como no exterior, apresentam vários requisitos aos quais os SPP devem atender. Contudo, a maioria destes requisitos são relacionados somente à resistência estrutural e à configuração geométrica, negligenciando a eficiência e flexibilidade dos mesmos, bem como não tratam dos processos de montagem e desmontagem. As limitações nos requisitos considerados em diversas fontes e a falta de métodos para verificar a conformidade dos SPP aos requisitos das normas (e outros requisitos relevantes) criam dificuldades para as partes interessadas, tais como órgãos governamentais de fiscalização, empresas construtoras, e os próprios operários encarregados pela execução dos SPP. O objetivo deste trabalho é propor um conjunto de requisitos de desempenho para sistemas temporários de proteção periférica. Estes requisitos foram identificados a partir de várias fontes de evidencia, tais como regulamentos, observações diretas de operações de montagem e desmontagem dos SPP em obras, análise de projetos de SPP, e entrevistas com especialistas. Deste modo, foi identificado um conjunto de 33 requisitos: 15 relativos à segurança, 12 à eficiência e 6 à flexibilidade. Com base nos referidos requisitos, foram avaliados 9 tipos de SPP, em 26 canteiros de obra. Estes SPP foram agrupados em três categorias de acordo com os materiais constituintes: metálicos, madeira e mistos. As principais contribuições deste estudo referem-se ao desenvolvimento de um conjunto amplo de requisitos, à análise das relações entre estes requisitos, indicando se estes podem reforçar-se mutuamente ou estar em conflito, e a proposição de um protocolo que torna claro as premissas adotadas em cada etapa da avaliação. / In the construction industry falls from height are one of the most frequent types of serious accidents. There are a number of factors that contribute for such falls, such as the lack of training for workers, layout constraints, and the lack of fall protection barriers. Although the use of temporary edge protection systems (TEPS) is an important measure to prevent falls from height in construction sites, the literature does not present a comprehensive set of requirements for those systems. Safety and health standards in construction, both in Brazil and abroad, have several requirements to which the SPP should meet. However, most of those standards are limited to structural strength and geometric configuration requirements, neglecting efficiency and flexibility, as well as do not address the assembly and disassembly processes. The limitations of requirements considered in several sources, and the lack of methods to verify the conformance of TEPS to the requirements established in standards (and other relevant requirements) create difficulties for stakeholders, such as government supervisory bodies, construction companies, and the workforce involved in the installation of TEPS. The aim of this study is to propose a set of performance requirements for temporary edge protection systems. These requirements have been identified from various sources, such as standards, direct observation od assembly and disassembly operations, analysis of TEPS design, and interviews with specialists. Thus, a set of 33 requirements were identified: 15 related to safety, 12 to efficiency and 6 to flexibility. Based on those requirements 9 TEPS solutions were evaluated in 26 construction sites. Those solutions were divided into three categories according to the materials used: metal, wood and mixed. The main contributions of this investigation refers to the development of a broad set of requirements, the analysis of the relationships between those requirements, indicating that these can either reinforce each other or be in conflict, and the proposal of a protocol that makes it clear the assumptions made at each evaluation stage.
