2. 1. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle

   Author : Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

   Abstract : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. READ MORE

4. 2. Scheduling Algorithms For Fault-Tolerant Real-Time Systems

   Author : Risat Pathan; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Online Scheduling; Partitioned Scheduling; Rate-Monotonic Scheduling; Multiprocessors; Uniprocessor; Task-Splitting Algorithms; Periodic Task Scheduling; Real-Time Systems; Fault-Tolerant Scheduling;

   Abstract : This thesis deals with the problem of designing efficient fault-tolerant real-time scheduling algorithms for independent periodic tasks on uni- and multiprocessor platforms. The well-known Rate-Monotonic (RM) scheduling algorithm is assumed as it is widely used in many commercial systems due to its simplicity and ease of implementation. READ MORE

5. 3. A real-time simulation-based optimisation environment for industrial scheduling

   Author : Marcus Frantzén; Philip Moore; David Stockton; Amos Ng; Stephen Newman; Riham Khalil; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling system; Simulation; Scheduling; simulation-based optimisation; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Abstract : In order to cope with the challenges in industry today, such as changes in product diversity and production volume, manufacturing companies are forced to react more flexibly and swiftly. Furthermore, in order for them to survive in an ever-changing market, they also need to be highly competitive by achieving near optimal efficiency in their operations. READ MORE

6. 4. Short-term Underground Mine Scheduling : Constraint Programming in an Industrial Application

   Author : Max Åstrand; Mikael Johansson; Christian Schulte; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; mining; mine; underground; constraint programming; cp; large neighborhood search; lns; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The operational performance of an underground mine depends critically on how the production is scheduled. Increasingly advanced methods are used to create optimized long-term plans, and simultaneously the actual excavation is getting more and more automated. READ MORE

7. 5. Short-term Underground Mine Scheduling : An Industrial Application of Constraint Programming

   Author : Max Åstrand; Mikael Johansson; Mats Carlsson; KTH; []
