1. 1. En fallstudie om svenska flottans utövande av uppdragstaktik

   Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

   Författare :Pauline Pihlsten; [2023]
   Nyckelord :Uppdragstaktik; fartyg; besättning; tillämpning; militär verksamhet;

   Sammanfattning : Mission command is broadly known and used in military organisations all over the world, and a lot of research has been done about its practical use in different nations armed forces. Although mission command is widely used and well-spoken for, its usage in a naval context is practically unresearched. LÄS MER

3. 2. Evaluation of IMO second-generation intact stability criteria and examination of different fishing vessel designs to dead ship condition and excessive acceleration failure mode

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Pavlos Liatsis; [2023]
   Nyckelord :Ship Design; Second Generation Intact Stability Criteria; Excessive Acceleration; Fishing Vessels; Skeppsdesign; andra generationens intakt stabilitetskriterier; kraftiga acceleration; fiskefartygsskrovs;

   Sammanfattning : The main objective of this project is to investigate the applicability of the IMO second-generation intact stability criteria in enhancing the process of designing fishing vessels, which often face stability challenges due to their narrow hulls and harsh operating environments. The study involves analyzing the impact of these criteria, specifically focusing on dead ship conditions and Level 1 and Level 2 excessive acceleration criteria, on the design of three fishing vessels.

4. 3. At the Heart of the Critical Vulnerability : Exploring Organizational and Technological Flexibility in Coastal Defense Anti-Ship Missile Warfare

   Master-uppsats, Försvarshögskolan

   Författare :Jan-Erik Linell; [2022]
   Nyckelord :Anti-Ship Missile; Coastal Defense; Naval Tactics; Anti-Surface Warfare; Organizational Flexibility; Technological Flexibility; Redundancy; Versatility; Balance; Missile Salvo Model;

   Sammanfattning : In coastal defense operations, anti-ship missile (ASM) attacks on amphibious assault high value targets (HVT) constitutes a window of opportunity with decisive potential. However, in war, the availability and performance of ASM-forces is uncertain and most likely less than ideal. LÄS MER

5. 4. Survivability Prediction and Analysis using Interpretable Machine Learning : A Study on Protecting Ships in Naval Electronic Warfare

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Sidney Rydström; [2022]
   Nyckelord :Electronic warfare; machine learning; statistics; Artificial Neural Networks; ANN; multi-layer perceptron; multi-task learning; interpretable machine learning; Shapley values; kernel SHAP;

   Sammanfattning : Computer simulation is a commonly applied technique for studying electronic warfare duels. This thesis aims to apply machine learning techniques to convert simulation output data into knowledge and insights regarding defensive actions for a ship facing multiple hostile missiles. LÄS MER

7. 5. Introduction of UXV assets into naval fleet architectures through an MILP based fleet modelling tool

   Master-uppsats, KTH/Marina system

   Författare :Sjoerd Jan Sinnema; [2021]
   Nyckelord :Numerical cost optimization; Naval fleet modelling; UXV integration; MILP programming; Maritime engineering; Numerisk kostnadsoptimering; flottmodellering; UXV -integration; MILP -programmering; sjöfartsteknik;

   Sammanfattning : The problem of fleet design and fleet modelling; for decades problems regarding determining fleet sizes and optimized routing problems have formed the groundwork into the fleet design and fleet optimization for a wide range of business sectors. In most of these problems only single entities or fixed design resources are optimized for a certain route and delivery objective based on minimizing operational costs. LÄS MER
