1. 1. Optimisation methods for solving a large-scale avionics scheduling problem

   Författare :Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

   Sammanfattning : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

4. 3. Cluster Scheduling and Management for Large-Scale Compute Clouds

   Författare :Mina Sedaghat; Erik Professor; Omer Rana; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cloud computing; Scheduling; Resource Management;

   Sammanfattning : Cloud computing has become a powerful enabler for many IT services and new technolo-gies. It provides access to an unprecedented amount of resources in a fine-grained andon-demand manner. To deliver such a service, cloud providers should be able to efficientlyand reliably manage their available resources. LÄS MER

5. 4. Coordination of Heavy-Duty Vehicle Platooning

   Författare :Sebastian van de Hoef; Dimos V. Dimarogonas; Simona Sacone; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. Five papers on large scale dynamic discrete choice models of transportation

   Författare :Oskar Blom Västberg; Anders Karlström; R. Daniel Jonsson; Marcus Sundberg; Karin Brundell-Freij; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Sammanfattning : Travel demand models have long been used as tools by decision makers and researchers to analyse the effects of policies and infrastructure investments. The purpose of this thesis is to develop a travel demand model which is: sensitive to policies affecting timing of trips and time-space constraints; is consistent with microeconomics; and consistently treats the joint choice of the number of trips to perform during day as well as departure time, destination and mode for all trips.
