2. 1. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

   Author : Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. READ MORE

4. 2. Languages and Tools for Optimization of Large-Scale Systems

   Author : Johan Åkesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper Machine Modeling; Plate Reactor; Languages for Physical Modeling; Compiler Construction; Dynamic Optimization; Modelica; Optimica; Manual Control; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Modeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. READ MORE

6. 4. Coordination of Heavy-Duty Vehicle Platooning

   Author : Sebastian van de Hoef; Dimos V. Dimarogonas; Simona Sacone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road freight transport; optimization; optimal control; automatic control; fuel-efficiency; match-making; off-board; intelligent transport systems; automated driving; clustering; scheduling; cooperative; large-scale; dynamic programming; trucks; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A network-wide coordination system for heavy-duty vehicle platooning with the purpose of reducing fuel consumption is developed. Road freight is by far the dominating mode for overland transport with over 60 % modal share in the OECD countries and is thus critically important for the economy.

7. 5. Numerical and Symbolic Methods for Dynamic Optimization

   Author : Fredrik Magnusson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic optimization; differential-algebraic equations; Modelica; direct collocation; block-triangular ordering;

   Abstract : Mathematical optimization is becoming increasingly important for engineering in general and control in particular. This thesis deals with numerical methods, primarily direct collocation, and symbolic methods, primarily block-triangular ordering and tearing, for numerical solution of general dynamic optimization problems involving dynamical systems modeled by large-scale differential-algebraic equations (DAE).
