  1. 1. A generic construction process modelling method

    Detta är en avhandling från Institutionen för fastigheter och byggande

    Författare :Vesa Karhu; KTH.; [2001]
    Nyckelord :process; modelling; generic; method; database; view;

    Sammanfattning : A variety of modelling methods has been used to modelconstruction processes and projects, either during normalproject planning or for process re-engineering efforts orresearch. One common method, which is widely used byconstruction industry practitioners, is scheduling. LÄS MER

  2. 2. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance

    Detta är en avhandling från Chalmers University of Technology

    Författare :Stefan Heyne; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; synthetic natural gas; biomass; gasification; energy systems; performance indicators; process modelling;

    Sammanfattning : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest. LÄS MER

  3. 3. Model-Driven Process Design Aligning Value Networks, Enterprise Goals, Services and IT Systems

    Detta är en avhandling från Stockholm : Department of Computer and Systems Sciences, Stockholm University

    Författare :Erik Perjons; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; business process design; e-process design; model-driven methods; enterprise modelling; business modelling; enterprise goals; services; value networks; business-IT alignment; design science; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. LÄS MER

  4. 4. Simulations of Evaporation Plants in Kraft Pulp Mills: Including Lignin Extraction and Use of Excess Heat

    Detta är en avhandling från Chalmers University of Technology

    Författare :Marcus R. Olsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemisk process- och produktionsteknik; Chemical process and manufacturing engineering; Energy-efficient evaporation; simulation; heat integration; process integration; excess heat; lignin extraction; energy saving; modelling; kraft pulp mill.;

    Sammanfattning : In this thesis, evaporation plants at kraft pulp mills are simulated with the purpose of making them more energy efficient. The work is important since energy saving is assumed to be one of the major solutions for handling the world's energy demand in the future. LÄS MER
