1. 16. An Optimization Model for Electric Vehicle Routing with Tractor Swapping

   University essay from KTH/Matematik (Avd.)

   Author : Alexander Strid; Daniel Liu; [2022]
   Keywords : Vehicle Routing Problem VRP ; tractor swapping; electric VRP; rich VRP; heavy goods vehicles; mixed-integer linear programming MILP ; applied mathematics; ruttoptimering; traktorbyte; elektriska lastbilar; tunga lastbilar; linjär heltalsoptimering; tillämpad matematik;

   Abstract : The purpose of this thesis is to investigate how tractor swapping can be implemented in Vehicle Routing Problems (VRP) with electric heavy goods vehicles, and to evaluate how a model that allows for tractor swapping performs, in terms of schedule cost, against a model that does not. Hence, this thesis introduces a new rich VRP variant which includes tractor swapping, as well as time windows, pickup and delivery, and electric vehicles. READ MORE

4. 18. Introduction of UXV assets into naval fleet architectures through an MILP based fleet modelling tool

   University essay from KTH/Marina system

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

   Abstract : 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. READ MORE

5. 19. Open Source Grid Expansion Models for the EU Project Spine

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Akshaya Tammanur Ravi; [2021]
   Keywords : Expansion Planning; Renewable Energy Sources; Operational Variability; Representative Days; Long-term Uncertainties; Stochastic Optimization; Utbyggnadsplanering; Förnybara energikällor; Variabel driftsituation; Representativa dagar; Långsiktiga osäkerheter; Stokastisk optimering;

   Abstract : Modern power systems are at the forefront of addressing the transition towards a decarbonized energy system, with increased integration of renewable energy sources becoming the key means to achieve the same. In this context, an expansion planning problem provides a decision support framework for investments in new generation and transmission assets over a long time-frame, addressing a wide range of technical and economic criteria aligned with national policies.
