  1. 1. Capacity Constraints in Multi-Stage Production-Inventory Systems Applying Material Requirments Planning Theory

    University dissertation from Institutionen för produktionsekonomi

    Author : Thi Thu Thuy Huynh; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Requirements Planning; Laplace transform; Net Present Value; multi-stage multi-level production-inventory planning; TECHNOLOGY Industrial engineering and economy; TEKNIKVETENSKAP Industriell teknik och ekonomi;

    Abstract : In this thesis, capacity-constrained aspects of multi-level, multi-stage productionplanning are investigated. The aim has been to extend Material Requirements Planning Theory (MRP Theory) to cover more general problems dealing with capacity constraints, in particular when non-zero lead times are present and the processes take place in continuous time.

  2. 2. Modeling Solute Transport in Fractured Rocks-Role of Heterogeneity, Stagnant Water Zone and Decay Chain

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Batoul Mahmoudzadeh; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solute transport model; Fractured rock; Stagnant water zone; Rock matrix diffusion; Radionuclide decay chain; Geological layers; Laplace transform; Simulation;

    Abstract : A model is developed to describe solute transport and retention in fractured rocks. It accounts for the fact that solutes not only can diffuse directly from the flowing channel into the adjacent rock matrix composed of different geological layers but can also at first diffuse into the stagnant water zone occupied in part of the fracture and then from there into the rock matrix adjacent to it.

  3. 3. Capacity-constrained production-inventory systems : using Laplace transforms and input-output analysis

    University dissertation from Linköping : Linköpings universitet

    Author : Zhiping Wang; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Production-Inventory Systems; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : This work is concerned with multi-level, multi-stage capacity-constrained production-inventory problems. The aim is to provide a contribution to a theoretical background for Material Requirements Planning (MRP) using the Laplace Transform approach and Input-Output Analysis. READ MORE

  4. 4. Connect Modelling Learning to Facilitate Linking Models and the Real World trough Lab-Work in Electric Circuit Courses for Engineering Students

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Anna-Karin Carstensen; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Education; Engineering Education Research; Key concepts; Labwork; Laplace Transforms; Learning; Learning of a Complex Concept; Learning to model; Modelling learning; Models; Practical Epistemologies; Threshold concepts; Variation Theory;

    Abstract : A recurring question in science and engineering education is why the students do not link knowledge from theoretical classes to the real world met in laboratory courses.Mathematical models and visualisations are widely used in engineering and engineering education. READ MORE

  5. 5. Engineering problem solving : The case of the Laplace transform as a difficulty in learning in electric circuits and as a tool to solve real world problems

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Margarita González Sampayo; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; engineering students; understanding; electric circuit theory; learning engineering; SOCIAL SCIENCES Social sciences Education; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik;

    Abstract : For engineers it is important to be able to use the ’skill’ of for example handling novel situations in powerful ways and to develop and design. They are expected to be able to understand theories and models and their connection to objects and events in the physical world and being able to apply these models and theories. READ MORE
