  1. 1. Modeling Lateral Transshipments and Perishable Items in Inventory Systems

    Författare :Fredrik Olsson; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Teknik; Dynamic programming ; Inventory ; Perishable items ; Lateral transshipments ; Pooling ; Batch ordering ; Optimal policies ; Stochastic ;

    Sammanfattning : This thesis deals with two main areas in the field of stochastic inventory theory; ateral transshipments and perishable items. In the first part of this thesis we give an introduction to the field of inventory theory, and discuss some previous literature connected to the research presented in this thesis. LÄS MER

  3. 2. Lithium-ion batteries for off-grid PV-systems

    Författare :Fabian Benavente; Göran Lindbergh; Anders Olof Lundblad; Saul Cabrera; Daniel Abraham; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; aging; partial cycles; DVA; EIS; NCA; stationary energy systems; PV systems; rural electrification.; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis provides a comprehensive and detailed analysis on the effect ofthe battery operation strategy on the lifetime of commercial lithium-ionbatteries and on the economics of off-grid photovoltaic (PV)-batterysystems.Lithium-ion batteries play a key role in the transition to a fossil-freesociety.

  4. 3. Analysis of Lateral Transshipments in Inventory Systems

    Författare :Stefan Vidgren; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Queueing theory; Inventory control; Stochastic; Lateral transshipments; Optimization;

    Sammanfattning : This thesis is based on two scientific papers. In these papers we study how one can approximate the inventory level of probabilities and the transshipment rates for inventory systems that apply lateral transshipment policies. LÄS MER

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

    Författare :Zhiping Wang; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Production-Inventory Systems; Computer science; Datavetenskap;

    Sammanfattning : 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. LÄS MER

  7. 5. Coordinated Multi-Stage Inventory Systems with Stochastic Demand

    Författare :Jonas Andersson; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Management of enterprises; Produktionsteknik; Production technology; Nash Equilibria; Multi-Echelon; Coordination; Stochastic; Supply Chain; Inventory Control; Företagsledning; management;

    Sammanfattning : This thesis is based on six scientific papers providing different methods for coordinated inventory control in supply chains. The main focus is on supply chains in connection with distribution of products to customers. Two different problem areas are considered. LÄS MER
