While studies of the subject show that an environmental friendly supply chain is considered a success factor for many companies, there is a lack of interest from them to invest in order to obtain it. The question this dilemma raises is what a company can do in terms of reducing its impact on the environment without making big investments. The purpose of this thesis is to investigate how, from a company perspective, efficient logistics solutions for the distribution of products can reduce transportation costs as well as the environmental impact from a company. To gather data the authors will conduct a qualitative single case study in the form of interviews at a company to create the deep understanding needed to comprehend a company’s distribution system. The result of the analysis shows that areas considering fill rate and selection of transportation mode are findings that would increase the efficiency, which would reduce the cost of transportation and the environmental impact. Also benefits from the option to outsource the logistics function regarding the distribution of the product to a TPL have been found. The conclusion suggests that for a company to become as efficient as possible, while at the same time reduce their negative impact on the environment they should try to maximize the fill rate, which brings along that as much goods as possible is being distributed with as limited amounts of transportations as possible.

Navettage et épuisement professionnel selon la région et le moyen de transport : les résultats de l'étude SALVEO

Barreck, Annie 02 1900 (has links)
L’objectif principal de ce mémoire est l’étude de la relation entre le navettage, soit le fait de faire la navette quotidiennement entre le domicile et le travail, et l’épuisement professionnel. Plus précisément, les rôles de modération du moyen de transport et de la région du milieu de travail, tant distinctement que simultanément, sur la relation entre la durée et la distance de navettage et l’épuisement professionnel sont examinés. L’épuisement professionnel a été mesuré grâce au MBI-GS (Maslah Burnout Inventory – General Survey). Les données proviennent de l’étude SALVEO menée au Canada par l’Équipe de Recherche sur le Travail et la Santé Mentale (ERTSM). Les données ont été recueillies entre 2009 et 2012 dans 63 milieux de travail selon un taux de réponse de 71.3 %, équivalent à 2162 employés. Les multiples analyses de régression effectuées sont pamis lespremières à lier significativement le navettage à l’épuisement professionnel. En effet, les navetteurs qui travaillent en grandes régions urbaines sont significativement plus épuisés émotionnellement que les travailleurs des petites régions urbaines ou des régions rurales. Il existe une relation curvilinéaire entre la durée de navettage et la dimension du cynisme. Une relation curvilinéaire existe également entre la durée de navettage et la mesure globale de l’épuisement professionnel. Enfin, le moyen de transport ainsi que la région dans laquelle se situe l’établissement de travail modèrent simultanément la relation entre la durée de navettage et la dimension de l’efficacité professionnelle. Globalement, les résultats suggèrent que le stress de navettage provient de l’ajustement quotidien des travailleurs à leurs conditions de navettage, qui se répercute en emploi. Les organisations devraient donc s’intéresser au développement de pratiques de gestion en ressources humaines misant sur l’amélioration des conditions de navettage de leurs employés. Ces pratiques RH pourraient moduler la relation entre le navettage et les problèmes de santé mentale au travail. / The main goal of the thesis was to study the relationship between commuting and burnout. Specifically, we assessed the moderation effect of both the mode of transportation and the workplace areas, distincly and simultaneously, on the relationship between commuting duration and distance with burnout, Burnout was measured using the MBI-GS (Maslah Burnout Inventory-General Survey). Data was collected during the SALVEO Canadian study by the Équipe de Recherche sur le Travail et la Santé Mentale (ERTSM) between 2009 and 2012 in 63 workplaces. 2,162 employees participated, resulting in a response rate of 71.3%. The multiple regression analysis performed are among the firsts to significantly associate commuting to burnout. Indeed, commuters who work in large urban areas are significantly more emotionally exhausted than workers in small urban or rural areas. There is a curvilinear relationship between commuting time and dimension of cynicism. A curvilinear relation also exists between commuting time and the overall measure of burnout. Finally, the means of transport as well as the workplace area simultaneously moderate the relationship between commuting time and dimension of inefficacy. Overall, results suggest that the stress of commuting comes from the daily adjustment of workers to their commuting conditions, which is reflected in employment. Organizations should therefore be interested in the development of human resources management practices focusing on improving their employees' commuting conditions. These HR practices could modulate the relationship between commuting and mental health problems at work.

Hyperloop in Sweden : Evaluating Hyperloops Viability in the Swedish Context / Hyperloop i Sweden : Utvärdering av Hyperloops Möjligheter i den Svenska Kontexten

Magnusson, Fredrik, Widegren, Fredrik January 2018 (has links)
Transportations role in society is increasingly important and today it has a prominent role in business, citizens lives as well as in the world economy. The increasing globalization and urbanization puts significant pressure on the existing transport system, with increasing demand for high-speed travel. However, this comes with implications on the environment, and the environmental concerns constitutes one of the biggest pressures in transport. And as the contemporary modes are bound by their technologies, enabling marginal rather than radical improvements, a possible window of opportunity for new radical technologies to enter the market can emerge. One new technology emerging within transportation today is called hyperloop, a technology that could prove to meet demand for faster, cheaper, safer and more environmentally efficient transportation. However, the technology is still in an early stage of development and hence surrounded by major uncertainties. Further, the nature of the technology necessitates overcoming several obstacles before it can reach commercial practice. And this together with a limited knowledge of the concept in Sweden makes it difficult to predict if hyperloop can become a viable transport alternative on the Swedish market. Which condensed lays the foundation to the purpose of this paper: "To give an overarching understanding of the Swedish transport market dynamics, together with a comprehensive evaluation of the hyperloop concept. And hence contribute to more inclusive knowledge and understanding of hyperloop’s viability in the Swedish context." Since the phenomenon has not been comprehensively studied previously, the elected research design is that of an exploratory case study, with an inductive, qualitative approach. To address the purpose, a literary review of the theoretical field was conducted. Looking in to previous research on disruptive innovation, diffusion of innovations, technical transitions, transformational pressure as well as window of opportunity. The empirical material gathered during the research process was derived from two main channels. Firstly, an extensive review of scientific articles about the hyperloop technology was conducted, providing insights on the technology and its surroundings. This was complemented by qualitative interviews to obtain material on the dynamics of the Swedish transport market as well as for understanding hyperloop in the Swedish context. The empirical study was further accompanied by a review of news articles and websites to map the most recent progress in the hyperloop development. By analyzing the empirical material through three frameworks; Characteristics of Diffusion, the Multi-Level Perspective (MLP) and Technology Readiness Level (TRL), interesting findings and conclusions were drawn. These together points towards that hyperloop, if the technology reaches its predicted performance, will have significant relative advantages and observable effects in the relation to the contemporary modes of transportation. Further, a noticeable window of opportunity, sprung from capacity shortages and pressure towards environmental sustainability, seems to exist on the Swedish market. A window which could be capitalized upon and justify hyperloop in the Swedish context. The current state of the technology does however come with implications as it so far is insufficient to decrease uncertainty amongst the potential adopters. Factors that likely will prolong the adoption of the technology in Sweden relates to the relative complexity of the system, its limited compatibility with existing practices and the low maturity of the technology. Hence, the hyperloop companies must prove the concept feasible and increase the maturity to gain sufficient acceptance and recognition. This paper contributes to the academic community by assessing the compatibility of hyperloop on the Swedish market, as well as if hyperloop could become a viable alternative transport solution in Sweden. It provides insight to specific perspectives of the Swedish market, its requirements and the demand for alternative transport solutions. Hence, this paper is considered to make both an analytical contribution in terms of evaluating the viability of disruptive technologies. And an empirical contribution by shedding light on new important insights for the potential diffusion of hyperloop. Insights that are significant for hyperloop actors as well as for dominant actors on the Swedish transport market. / Transporters roll i samhället blir allt viktigare och de har idag en framträdande roll inom näringsliv, medborgares liv samt världsekonomin. Den ökande globaliseringen och urbaniseringen sätter dock ett betydande tryck på det existerande transportsystemet, med ökande efterfrågan för höghastighetsalternativ. Detta medför implikationer för miljön, och oron kring transporters miljöpåverkan är ett av de största bekymren för transportsektorn. Eftersom de existerande transportalternativen är bundna av sin teknik, vilket begränsar dem till inkrementella snarare än radikala förbättringar, kan en möjlighet för nya transportsätt att komma in på marknaden öppna sig. En kommande ny teknik som utvecklas inom transport idag kallas hyperloop, en teknik som kan visa sig möta efterfrågan för snabbare, billigare, säkrare och mer miljösmarta transporter. Tekniken är dock i ett tidigt utvecklingsskede och är därav omgärdad av stora osäkerheter. Vidare kräver teknikens natur att flertalet hinder kommer att behöva överkommas innan tekniken kan nå kommersiellt bruk. Detta tillsammans med den begränsade kunskap som finns kring konceptet i Sverige gör det svårt att förutspå om hyperloop kan bli ett möjligt transportalternativ på den svenska marknaden. Kondenserat ligger detta till grund för syftet med den här uppsatsen: "Att ge en övergripande förståelse av dynamiken på den svenska transportmarknaden, tillsammans med en djupgående utvärdering av hyperloop konceptet. Och därav bidra till en mer inkluderande kunskap och förståelse kring hyperloops möjligheter i den svenska kontexten." Eftersom detta fenomen inte tidigare har studerats i större utsträckning valdes en forskningsdesign i form av en undersökande fallstudie med ett induktivt, kvalitativt tillvägagångssätt. För att adressera syftet gjordes en litterär översyn av det teoretiska fältet. Med inblickar i tidigare forskning kring disruptiv teknik, diffusion av innovation, tekniska övergångar, transformationstryck samt möjlighetsfönster. Det empiriska materialet till studien samlades in genom två kanaler i huvudsak. Först, genom en djupdykning i tidigare forskning och vetenskapliga artiklar relaterade till hyperlooptekniken, för att generera insikter kring tekniken och dess omgivning. Detta kompletteras med kvalitativa intervjuer för att erhålla material om dynamiken på den svenska transportmarknaden samt för att ge en förståelse av hyperloop i den svenska kontexten. Den empiriska studien kompletterades ytterligare med en översyn av nyhetsartiklar och webbplatser för att kartlägga de senaste framstegen i hyperlooputvecklingen. Genom att analysera det empiriska materialet med hjälp av tre ramverk; Egenskaper för Spridning av Innovation, Perspektiv i Multipla Nivåer (MLP) och Teknisk Mogenhetsnivå (TRL), kunde flertalet intressanta upptäckter och slutsatser dras. Vilka tillsammans pekar mot att hyperloop, om tekniken lyckas uppnå den predikterade prestandan, kommer att ha betydande relativa fördelar och synliga effekter i förhållande till dagens transportsätt. Vidare kan ett märkbart möjlighetsfönster, sprunget ur kapacitetsbrist och tryck mot miljömässig hållbarhet, identifieras på den svenska marknaden. Detta fönster skulle kunna kapitaliseras på och motivera hyperloop i den svenska kontexten. Teknologins nuvarande tillstånd har emellertid konsekvenser, eftersom den hittills inte är tillräcklig för att minska osäkerheten hos potentiella adopterare. Faktorer som sannolikt kommer att förlänga processen att adoptera tekniken i Sverige härstammar från systemets relativa komplexitet, dess begränsade kompatibilitet med befintliga metoder samt teknikens låga mogenhet. Därav är det essentiellt för hyperloopbolagen att bevisa konceptet möjligt och öka mogenheten för att få tillräcklig acceptans och erkännande. Detta arbete bidrar till det akademiska samhället genom att bedöma kompatibiliteten mellan hyperloop och den svenska marknaden, samt om hyperloop kan bli ett genomförbart transportalternativ i Sverige. Arbetet bidrar med insikter i specifika perspektiv på den svenska marknaden, dess krav samt efterfrågan för alternativa transportlösningar. Därav kan denna uppsats anses utgöra både ett analytiskt bidrag genom dess utvärdering av genomförbarheten av disruptiv teknik. Samt ett empiriskt bidrag genom att belysa viktiga insikter för den potentiella spridningen av hyperloop. Insikter som är viktiga för såväl hyperloopaktörer som de dominanta aktörerna på den svenska transportmarknaden.
