1. 6. Effect Oriented Planning in Military Mission Support Systems : Models and Heuristic Approaches

   Författare :Kristian Lundberg; Kaj Holmberg; Torbjörn Larsson; Stefan Engevall; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Today there are many aspects of model based planning, probably much more than for just 20 years ago. Today data is not the problem, data is everywhere, but the big issue is to understand how to gain advantage of data in decision making - a growing focus is now on modeling!This work is devoted to this task and can be seen as a three part study.

3. 7. Robust Verification and Identification of Piecewise Affine Systems

   Författare :Jakob Roll; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise affine systems; Verification; Robustness; Identification; Mixed-integer programming;

   Sammanfattning : iecewise affine systems constitute an important subclass of hybrid systems, and consist of several affine dynamic subsystems, between which switchings occur at different occasions. As for hybrid systems in general, there has been a growing interest for piecewise affine systems in recent years, and they occur in many application areas. LÄS MER

4. 8. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

   Författare :Nilsson Olof; Lennart Söder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... LÄS MER

5. 9. Supply chain optimization in the forest industry

   Författare :Helene Gunnarsson Lidestam; Mikael Rönnqvist; Jan Lundgren; Eldon Gunn; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supply chain; logistics; forestry; optimization; modelling; transportation; mixed integer programming models; försörjningskedjor; logistik; optimering; modellering; transportplanering; blandade heltalsproblem; skogsindustrin; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : The scope of this thesis is modelling and solving large-scale planning problems in the supply chain within the forest industry. Five research papers are included, the first three of which focus on the modelling, and the last two on the solution methods. LÄS MER

7. 10. Optimal Coordination of Flexible Manufacturing Systems, with Automatic Generation of Collision- and Dealock-Free Working Schedule

   Författare :Avenir Kobetski; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Visibility Graphs; Scheduling; A*; Mixed Integer Linear Programming; Discrete Event Systems; Velocity Balancing.; Robot Coordination; Supervisory Control Theory; Deterministic Finite Automata; Flexible Manufacturing;

   Sammanfattning : The ever more rapidly changing markets pose high demands on the modern industry, often making it necessary to have varied and frequently updated product portfolios. As a consequence, modern industrial systems need to be easily adaptable to different kinds of products, which makes the use of flexible manufacturing systems (FMS) increasingly popular. LÄS MER
