  1. 1. Circular production investments : What a circular production investment is and how it can be designed

    University essay from KTH/Produktionsutveckling

    Author : Lotta Bohlin; [2023]
    Keywords : Circular investments; production investments; production equipment; circularity; green design; Cirkulära investeringar; produktionsinvesteringar; produktionsutrustning; cirkularitet; grön design;

    Abstract : One of the biggest emitters of greenhouse gas in Sweden is the industry sector, and in order to reach the national and global environmental goals, a change is needed. To become an environmentally sustainable producer, the whole life cycle must be taken into consideration, from choice of resources, to production, to use, and End-of-Life treatment. READ MORE

  3. 2. Self-assessment for SMEs to address operational and environmental performance. : Combining SCOR, SustainableSCOR, and LCA methodologies in the food industry

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Franz Rothschild; [2022]
    Keywords : Supply chain management; environmental management; green supply chain management; sustainable chain management; performance measurement systems; SCOR; LCA; SustainableSCOR; SME;

    Abstract : As world population grows, so does the demand for resources exploitation and transformation. This, in turn, has an effect in the increase of the related wastes. Facing these challenges by designing and developing sustainable products and supply chains, processes, operations, and management is becoming increasingly important. READ MORE

  4. 3. Life Cycle Cost of Smart Wayside Object Controller

    University essay from KTH/Spårfordon

    Author : Filipp Zarov; [2021]
    Keywords : railway signalling system; interlocking; hardware; Object Controller; Smart Wayside Object controller; Lifecycle Cost; renewable energy sources; järnvägssignalsystem; ställverk; hårdvara; Utdelar; SWOC; livscykelkostnad; förnybara energikällor;

    Abstract : In a regional railway signalling system, object controllers are the devices responsible for controlling Track Side Equipment and act as interfaces for TSE with the interlocking computer and the Traffic control system. However, associated cabling (signal and power cabling) and civil works pose a major capital investment and it is a source of significant Capital and Operational expenses, particularly in rural areas, where accessibility andconnectivity to power grid and to the interlocking are a problem.

  5. 4. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

    Author : Daniel Kostet; [2018]
    Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

    Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

  6. 5. Probabilistic Life Cycle Costing : A Monte Carlo Approach for Distribution System Operators in Sweden

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Tim Ljunggren; [2017]
    Keywords : Probabilistic life cycle cost; investment decision; Monte Carlo simulation; Markov Chain; Probabilistisk livscykelkostnad; investeringsbeslut; Monte Carlo-simulering; Markovkedja;

    Abstract : Investments in power systems are characterized by large investment costs and uncertainties doto extended time frame. New consumption patterns in the electricity grid, as well as an aginggrid calls for modernization, new solutions and new investments. READ MORE
