Modeling and coordinated control of large interconnected multi-purpose reservoirs spread across a country is usually challenging. These systems are generally characterized by coupled water quantity and quality variables and multiple control objectives. Efficient control of these systems can be achieved through appropriate and accurate modeling of reservoir dynamics in tandem with an accurate weather...
In most real-world settings, a transportation plan requires modifications during execution. A thorough evaluation of transportation planning methods thus requires testing and comparison in a dynamic environment. We give conditions on a simulation environment that follow from this requirement, and propose a multi-agent simulator meeting these conditions. In addition, we propose a new measure that captures...
One key problem for canal system control is how to select appropriate performance indicators and how to tune the controller with these indicators. A canal system is a multi-input and multi-output (MIMO) system. The judging control performance can be extremely complicated. In this paper, frequently used canal system performance indicators are evaluated. Then these indicators are used individually to...
In the evacuation problem, departure time, route, and destination instructions are optimized to increase the effectiveness of the evacuation (i.e., more arrivals at the destinations). In literature, evacuation instructions are mostly optimized for a problem without uncertainty (the so-called nominal problem): one specific scenario regarding the system, the hazard and the evacuees is assumed. In this...
When cost is the main consideration and the costs are only determined by the total length of the network, the optimal network infrastructure roll-out between several nodes is determined by minimal spanning trees and Steiner minimal trees. We explain that when capacities also play a role in the cost function a minimal Gilbert network gives the cheapest network structure. However, these kinds of networks...
Sensor and sensor networks technology are becoming an increasingly important part of information management infrastructures. Challenges related to collection, processing, analysis and user-centric presentation depending of context are of particular interest. Furthermore, design and implementation of proper respond actions to sensor based information is gaining interest in many applications. In this...
