This report shows the value of knowing your processes inside a company. The methods used in to do this have been first of all through process mapping and for in depth study, process cards were used to measure the process time and total lead time. This showed the location of bottlenecks and overall process capacity. With the data collected, suggestion on how to decrease storage, throughput time and total lead time is given.The study has been conducted at Intelbras in San Jose, Santa Catarina, Brazil. Intelbras is a telecommunication company which produces telephones, security cameras and switchboards. Two production processes is studied, the Telefone Sem fio, SFL, which produce cordless telephones and Central, CAL, which produce switchboards.Through simulation this paper shows improvement suggestions on how to better handle the flow of material by introducing sequencing into the production and FIFO in the storage handling, everything in order to decrease total lead time and increasing throughput time.Process mapping has proved to be a great tool in order to understand how a production process works and integrates with other departments. In supplement of process cards, valuable data is collected and used for analysing further improvements such as making a balancing program and calculating where and how big buffers is needed at different processes. / Program: Industriell ekonomi - arbetsorganisation och ledarskap

A new approach to allocate environmental responsibility, the "value added-based responsibility" allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that - due to their position in global value chains - certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers.

Denna rapport grundar sig i Svenska Mässans planer på expansion och de krav på effektiv hantering och korta ledtider som det medför. Svenska Mässans unika förutsättningar vad gäller yta, bransch och placering medför ett komplext flöde av material. Flödet försvåras ytterligare av att lager och de hallar där eventen genomförs på ligger på olika plan. Den andra delen grundar sig i den litterära brist som finns kring den här typen av logistik. I rapporten introduceras därför ett nytt begrepp - Mässlogistik. Begreppet syftar till att beskriva de verksamhetsspecifika flöden och interna transporter som sker i en sådan speciell bransch som mässbranschen. Genom att definiering av begreppet samt identifiering och fördjupning i de ingående komponenterna, har förslag på hur just Svenska Mässan kan öka sin resurseffektivitet tagits fram. Förslagen är koncentrerade kring deras största problemområden och det som har mest negativ påverkan på flödena. Rapporten är således uppbyggd kring två frågeställningar: 1.     Hur kan lagerstrukturen i möbellagret ändras på Svenska Mässan för att uppnå en högre resurseffektivitet? 2.     Hur ska Svenska Mässan organisera sina interna transporter för att generera en högre resurseffektivitet? För att kunna ge svar på ovanstående frågeställningar har fallstudiemetoden använts där nuläget först har kartlagts för att användas som utgångspunkt och därefter analyserats. Det har gjort att en tydlig bild över problemområdena i form av ostrukturerat lager, bristande planering, hisskonkurrens och ineffektiva transporter har visat sig. Lösningarna på dessa problem har dels hämtats ur litteraturen och dels genom ett logiskt resonemang med inspiration från andra företag. Vidare har en ABC-analys genomförts, på de standardmöbler som används på Svenska Mässans event, vilket har varit en utgångspunkt för att skapa ett effektivare flöde vid in- och utleverans i lagret. Ett ytterligare led i att nå en högre resurseffektivitet, både vid lagring och transport, har varit ett förslag med specialkonstruerade vagnar som lastbärare. Genom en benchmarking på Volvo personvagnar har även kittning undersökts som alternativ för att på så vis kunna förpacka och säkerställa fyllnadsgraden i hissarna och därmed också minska konkurrensen om dessa. I dagsläget hämtar montörerna sitt material själva, vilket leder till att mycket tid används för förflyttningar mellan planen. För att motverka detta har ett förslag tagits fram med att använda sig av materialare. Tanken är att dessa ska förse montörer med allt material de behöver samt att kitta och sekvenslägga montermaterialet. Dessutom ska de ansvara för att hissarna används på ett mer effektivt sätt och därmed öka fyllnadsgraden.   Slutsatser som dragits under detta arbete är att kommunikation och planering är en av de viktigaste grundkomponenterna för att uppnå en högre resurseffektivitet i Svenska Mässans produktionsavdelning. Vidare har det konstaterats att det finns tid att spara genom effektiva transporter samt att utnyttja hissarnas kapacitet på ett mer fullständigt sätt. / This report takes it stance in the Swedish fair’s plans for an expansion and the requirements of effective handling and short lead-times that it implies. The Swedish exhibition and congress centre (SECC) and their unique set of prerequisites concerning space, industry and location results in a very complex flow of material. The complexity of the flow increases further as storage and exhibition halls are located on different floors. The report is of further interest as there is a lack of academic knowledge concerning logistics of this kind. Therefore, this report aims to introduce a new set of terms – exhibition logistics, with ambitions to describe the specific flows and internal transports existing in the exhibition hall industry. By identifying and defining the terms a proposal is given of how the SECC can increase their resource- efficiency.   The proposed advices are focused on the greatest problem areas and furthermore those areas affecting the flows to the highest extend. The report is composed around the following questions: 1.     How can the Swedish exhibition and congress centre’s storage structure and resource storage be changed in order to reach a higher resource-efficiency? 2.     How should the Swedish exhibition and congress centre organize its internal transports to generate greater resource efficiency? To be able to answer the questions above, a case study has been applied. Firstly, research have been undertaken to understand the present situation followed by an analysis of the same. This has given the authors a clear picture of the problem areas; unstructured storage, lack of planning, ineffective use of the elevators as well as inefficient transportations occurring at all times. The presented solutions have partly been collected from relevant academic literature and from an up to date discussion with inspiration from other actors in the current market place. Furthermore, an ABC – analysis have been carried out of the standard furniture’s being used during events at SECC. Proposals for using unique constructed wagons for transporting the equipment have been reported. Yet, this analysis is a further action in order to adapt a greater resource efficiency regarding storage and transportations. At the present time, the assemblers are collecting their material on their own, which results in time consuming movements between storage and working floors. In order to prevent this, the authors have presented a suggestion of using a person for preparing the material. The implication is that they should serve the assembler all material needed for completion and fit for display. Additionally, they should also be given the responsibility of making sure that the elevators are used in a more efficient manner, thereby increasing the occupancy level. The conclusions reflect the importance of two key components that must be improved in order to increase the efficiency in SECC production department - planning and communication. Moreover, it has been concluded that time can be saved by effective transportations and by using the elevators’ capacity to its maximum.

In an increasingly globalized world with more and more distributed international supply chains, sustainability studies and policies need to consider socioeconomic and environmental interactions between distant places. Studies of the global biomass metabolism investigate physical flows between and within nature and human systems, thus providing a useful basis for understanding the interrelatedness of changes in one place with impacts elsewhere. Various methodological approaches exist for studying the human-nature metabolism and estimating the land embodied in international trade flows, a core element of assessing telecouplings in the global land system. The results of recent studies vary widely, lacking robustness and thus hampering their application in policy making. This article provides a structured overview and comparative evaluation of existing accounting methods and models for calculating land footprints. We identify differences in available accounting methods and indicate their shortcomings, which are mainly attributable to the product and supply chain coverage and detail, and biases introduced by the use of monetary flows as a proxy for actual physical flows. We suggest options for further development of global land footprint accounting methods, particularly highlighting the advantages of hybrid accounting approaches as a framework for robust and transparent assessments of the global displacement of land use.

Effective implementation of resource policies requires consistent and robust indicators. An increasing number of national and international strategies focussing on resource efficiency as a means for reaching a green economy call for such indicators. As supply chains of goods and services are increasingly organised on the global level, comprehensive indica-tors taking into account upstream material flows associated with internationally traded products need to be compiled. Particularly in the last few years, the development of con-sumption-based indicators of material use also termed material footprints has made considerable progress. This paper presents a comprehensive review of existing methodol-ogies to calculate material footprint-type indicators. The three prevailing approaches, i.e. environmentally extended input-output analysis (EE-IOA), coefficient approaches based on process analysis data, and hybrid approaches combing elements of EE-IOA and process analysis are presented, existing models using the different approaches discussed, and advantages and disadvantages of each approach identified. We argue that there is still a strong need for improvement of the specific approaches as well as comparability of re-sults, in order to reduce uncertainties. The paper concludes with recommendations for further development covering methodological, data and institutional aspects.

Based upon the upper bound limit analysis, the stability numbers have been developed for a two-layered soil slope both for an associated flow rule material and for a homogeneous slope with non-associated flow rule material. The failure surface was assumed to be an arc of logarithmic spiral and it automatically ensures the kinematics admissibility of the failure mechanism with respect to the rigid rotation of the soil mass about the focus of the logarithmic spiral. The effect of the pore water pressure and horizontal earthquake body forces was also included m the analysis. For a non-associated flow rule material, the stress distribution along the failure surface was developed with the assumption of interslice forces given by Fellenius and Bishop. The stability numbers have been found to reduce appreciably with increases m the (i) horizontal inclination (β) of slope, (ii) pore water pressure coefficient, ru and (iii) horizontal earthquake acceleration coefficient (kh). The values of the stability numbers for a non-associated co-axial flow rule, with dilatancy angle ψ =0, have been found to be considerably lower as compared to the associated flow rule material. For a given height of the slope, with associated flow rule, the values of the stability numbers have been found to increase with increase in the thickness of a layer with greater value of the friction angle Φ. The results have been given in the form of non-dimensional stability charts, which can be used for readily obtaining either the value of the critical height or the factor of safety The methodology can be easily extended even for multi-layered soil slopes with different values of cohesion (c), bulk unit weight (γ) and friction angle (Φ). An attempt has also been made in this thesis to study experimentally the effect of the frequency of the excitation and the addition of non-plastic fines on the liquefaction resistance of the material Shake table studies, generating uni-axial sinusoidal horizontal vibrations, were earned out for this purpose. During the period of excitation of the material, the settlement at the surface of the sample increases continuously with time up to a certain peak value and thereafter, it becomes almost constant. For the excitation of the material with higher frequency, more number of cycles was seen to reach the final settlement. With the continuous excitation of the material, the magnitude of the pore water pressures increases up to a certain peak value and there after, its magnitude decreases till it again becomes the hydrostatic pressure as it was before the excitation of the material. The peak magnitude of the pore water pressure tends to be higher for the excitation with smaller frequency especially at greater depths from the ground surface. The addition of non-plastic fines tends to increase the magnitude of the settlement as well as the increase in the pore water pressure.

The construction industry in Sweden today is a busy market. The demand for new residences is very high and many are recruited to the industry for companies to be able to meet the demand. Generally a construction site needs temporary construction facilities for staff to manage administrative tasks and have conferences, eat, rest, shower etc. The purpose of this study is to investigate how the temporary construction site facilities can be established to better promote communication, cooperation, flow of people, flow of material, comfort and well-being. To identify problem areas and potential solutions, interviews were conducted with people from different working categories. Through interviews and own observations, the authors chose popular potential solutions and improvement opportunities and tested them on larger amount of people in a survey. By visiting a number of construction sites and their temporary facilities it was found that there are many ways to establish them. General solutions were made for bigger and smaller establishments, for example where to allocate different workspaces or how to use visual management in the best way. Suggestions were made on how to adjust furniture easier by using a system of holding strips and rails. Factors such as a relax rooms, paintings and plants were suggested to would improve comfort and well-being. Finally, conclusions could be made in different areas. More random interaction between working categories would improve communication and promote a nice working environment. An area especially made for these interactions with a strategic placed coffee machine could increase interaction. Offices should be allocated in a way that makes the ones responsible for the blue collar workers easier to reach. The ones who perform more administrative tasks throughout the day, like the site manager, should be allocated far from the entrance, to minimize the risks of disruption. Conference rooms should be placed furthest in the establishment, in that way meetings will not be interrupted. Today there is too little focus on the little things that could improve comfort and well-being. More comfortable chairs, tables that can be adjusted in height, white walls and so on are examples on what could be done differently. / I Sverige råder idag en högkonjunktur i byggbranschen. De flesta städerna har brist på bostäder, vilket leder till långa köer, och pressen att bygga nytt är stor. Allt fler rekryteras till byggbranschen för att möta behovet. Byggarbetsplatser kräver att arbetarna har utrymmen som arbetarna kan nyttja på raster, administrativa arbeten och sköta hygienen i. Vanligen är dessa utrymmen i form av bodetableringar. I denna rapport undersöks hur bodetableringar kan utformas för att främja kommunikation, flöden och trivsel. Syftet är att ta fram konkreta förbättringsförslag gällande nämnda områden. För att få en bild av nuläget och identifiera förbättringsområden har författarna besökt ett antal etableringar, både från uppdragsgivaren Skanska och från andra företag. Personer från olika yrkesgrupper har intervjuats för att ta fram åsikter och förbättringsförslag från alla som har bodarna som sin arbetsplats. Utöver intervjuer och egna observationer gjordes en enkätundersökning för att få mer tyngd i de förbättringsförslag som uppkommit. Under arbetets gång visade det sig att utformning av bodetableringar ser mycket olika ut beroende på hur stort projektet är, vilket företag som har projektet samt hur platschefens preferenser ser ut. Generella lösningar togs fram på hur mindre respektive större etableringar bör utformas för att främja kommunikation. Även vilka visuella tavlor och medel som kan användas. Förslag presenteras på hur material kan anpassas i bodarna på ett lättare sätt och därmed kunna använda samma rum till olika saker. Faktorer gällande hur bodar kan inredas för att öka trivseln tas fram. Slutsatser har kunnat dras inom många olika områden. Bland annat att mer slumpvisa möten inom bodarna skulle förbättra kommunikation och trivsel. En neutral yta, gärna i anslutning till en invändig trappa, gör det lättare för folk att mötas. Kontor och konferensrum bör placeras på ett sätt som gör arbetsledare tillgängliga för yrkesarbetare samtidigt som platschef och konferensrum ska finnas närmare slutet på etableringen då det ska vara mindre spring kring dem. Ett bärlist-system med skenor i bodarna borde införas för att de ska vara lättare att sätta upp tavlor, hyllor och möbler samt göra om ett rum om det behövs. Idag läggs för lite fokus på inredning i bodarna. Många vill se mer växter, tavlor, mattor och liknande för att öka nivån av trivsel.
