Meter Placement for State Estimation in distribution networks

With the increasing environmental concerns, the world is moving towards rapid decarbonization, and to meet the growing energy demand, more renewable energy sources like solar, Wind are getting added to the existing Distribution grid. The addition of new loads like Electric vehicles (EV), Heat pumps, etc. is putting additional pressure on the...

Heuristic-Based Approach for Near-Optimal Response to Water Distribution Network Failures in Near Real Time

This paper proposes a new method to identify the near-optimal response to failures in water distribution networks in near real time. The response method is formulated as a two-objective optimization problem with objectives being the minimization of failure impacts and related operational costs. The new heuristics-based method is developed and...

The use of systematic and heuristic methods in the basic design cycle: A comparative survey of students' method usage

In the present paper, we study the reported use of systematic and heuristic methods for 304 students enrolled in a master-level course on design theory and methodology. What to teach design and engineering students about methods is an important topic for discussion. One reason for this is that the experiences of design educators when using...

A Solution Method for Vehicle Routing Problems with Time-Dependent Travel Times

The goal of this thesis is developing an efficient method that produces good quality solutions to real-life Vehicle Routing Problems with time-dependent travel times. The Time-Dependent Vehicle Routing Problem (TDVRP) is one of the most challenging combinatorial optimisation problems and belongs to the category of NP-hard problems. Therefore,...

What is on the machine's mind? Models for reasoning with incomplete and uncertain knowledge

In this thesis, which consists of two parts, two different subjects are discussed. In the first part of the thesis a logic for reasoning with inconsistent knowledge will be described. The second part of the thesis contains a proposal for to view a reasoning process as a process of constructing a partial model of the world we are reasoning about....

Report 88-25 (Reviewed) TUD Faculty of Technical Mathematics and Informatics Heuristic reasoning

In this paper a model for heuristic reasoning with uncertain knowledge is presented. This model is a generalisation of the approach proposed by Clancey (Cla-84, Cla-85). We offer a clear semantics for the model, showing that the heuristic reasoning process can be given a clear probabilistic interpretation.
