1. 1. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

   Detta är en avhandling från Karlstad : Karlstads universitet

   Författare :Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Per Engstrand; [2018]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER

3. 2. A generic construction process modelling method

   Detta är en avhandling från Institutionen för fastigheter och byggande

   Författare :Vesa Karhu; [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

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

   Detta är en avhandling från Karlstads universitet

   Författare :Stefan Heyne; [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; process modelling; performance indicators; biomass; energy systems; synthetic natural gas; gasification;

   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

7. 5. 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; Paul Johannesson; Anders G. Nilsson; [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; Computer and Systems Sciences; data- och systemvetenskap;

   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
