  1. 1. Optimization of process integration investments under energy market uncertainties

    Författare :Elin Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; scenario-based modelling; investment planning; process integration;

    Sammanfattning : The increased climate concern in society puts pressure on industries to decrease their energy use in different ways, and a number of studies show that there is a large potential for improved energy efficiency in the energy-intensive industry, for example through process integration. Uncertainties about future energy prices and policy instruments make it, however, difficult to evaluate and compare different kinds of energy-saving measures with respect to net present value as well as reduction of CO2 emissions.

  3. 2. Optimization of Investments for Strategic Process Integration and Pulp Mill Biorefinery Projects under Uncertainty

    Författare :Elin Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pulp and paper industry; investment planning; biorefinery; scenario-based modelling.; stochastic programming; Process integration;

    Sammanfattning : Energy-intensive industrial plants operate in a changing, uncertain environment. Long-term changes are expected in energy prices, political regulations and technology development. Pulp and paper companies, like many other industries, are under strong pressure to respond to these changes. LÄS MER

  4. 3. Vehicle-in-the-loop validation of autonomous cars

    Författare :Angel Molina Acosta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backward reachability; scenario-based testing; multi-agent systems; Model Predictive Control;

    Sammanfattning : Validation of autonomous driving (AD) cars is a difficult task because of the complexity that results from the integration of multiple systems and the variety of operating conditions. To this end, testing with real vehicles is crucial to ensure a thorough validation of AD cars. LÄS MER

  5. 4. Modelling and Analysing Hospital Surgery Operations Management

    Författare :Marie Persson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; Simulation; Management; Healthcare; Mathematical programming;

    Sammanfattning : With an increasing proportion of elderly and an increasing demand for healthcare, managerial efforts are needed in order make the best use of resources and to keep cost under control. One of the most critical and expensive resources in a hospital is the operating theatre. LÄS MER

  7. 5. Draw control strategy for sublevel caving mines : A probabilistic approach

    Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Matthias Wimmer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control; sublevel caving; probability models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER
