Reliability of electrical transmission systems is presently managed by applying the deterministic N-1 criterion, or some variant thereof. This means that transmission systems are designed with at least one level of redundancy, regardless of the cost of doing so, or the severity of the risks they mitigate. In an operational context, the N-1 criterion(More)
This paper brings the preliminary results of interviews with Scandinavian managers and engineers asking questions regarding their previous experiences and knowledge on diverse continuous education methods and further encourages them to gaze into the crystal ball to identify requests and expectations to future methods of continuous education. The interviews(More)
In these presentation records we propose a procedure to increase robustness of production plans embedded in a modelling approach based on integrated multi-scale optimization models and solution methods for planning and scheduling of a make to order production process under uncertain and varying demand conditions. As an inspiration we have a large real world(More)
The objective of the paper is to simulate behavior of economic agents with a special emphasis on the use of the time resource in economic processes. The case studied, is brought from the fishing industry. With an aid of simulations, the study analyzes behavior of economic agents as they lead their processes through time. The paper estimates the value of(More)
This paper presents the use of genetic algorithms (GA) for solving the dual bin packing problem using fuzzy objectives. In bin packing problems, a list, L of items is to be packed into a minimum number of bins. In dual bin packing the items are packed into a maximum number of bins, assuring a minimum weight for each bin. We consider a class which we call(More)
This paper introduces a probabilistic reliability management approach and describes a pilot test planned by the Icelandic transmission system operator, Landsnet, in early 2017, as part of the EU GARPUR project. The pilot test will assess the viability of the approach and criteria proposed by GARPUR, in the context of real-time system operation. The(More)
