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

    Författare :Thi Thu Thuy Huynh; Robert Grubbström; Ludvik Bogataj; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Requirements Planning; Laplace transform; Net Present Value; multi-stage multi-level production-inventory planning; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : 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.

  3. 2. Studies on the competitiveness of wood : - market segmentation and customer need assessments

    Författare :Ragnar Jonsson; Roger Cooper; Växjö universitet; []
    Nyckelord :wood; building material; material substitution; end-consumer; floorcovering; customer needs; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Sammanfattning : Over the last decades, wood has encountered increasing competition from other building materials. Hence, it is relevant to study the underlying factors of material substitution. The market for repair and remodelling (R&R) is growing in importance. LÄS MER

  4. 3. Modelling and simulation of welding and metal deposition

    Författare :Andreas Lundbäck; Jesper Hattel; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Material Mechanics; Materialmekanik;

    Sammanfattning : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. LÄS MER

  7. 5. Affordances and Constraints of Intelligent Decision Support for Military Command and Control : Three Case Studies of Support Systems

    Författare :Ola Leifler; Henrik Eriksson; Patrick Lambrix; Bartel Van de Walle; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decision Support; planning; machine learning; information management; Command and Control; Computer science; Datalogi;

    Sammanfattning : Researchers in military command and control (C2) have for several decades sought to help commanders by introducing automated, intelligent decision support systems. These systems are still not widely used, however, and some researchers argue that this may be due to those problems that are inherent in the relationship between the affordances of technology and the requirements by the specific contexts of work in military C2.
