Review of Optimization Strategies for System-Level Design in Hybrid Electric Vehicles

The optimal design of a hybrid electric vehicle (HEV) can be formulated as a multiobjective optimization problem that spreads over multiple levels (technology, topology, size, and control). In the last decade, studies have shown that by integrating these optimization levels, fuel benefits are obtained, which go beyond the results achieved with...

Ensemble-based methods for well drilling sequence and time optimization under uncertainty

One of the main activities in the (re-)development of large hydrocarbon fields is the drilling of new wells. The drilling process may involve a large number of wells and take several years to complete. Challenges include the selection of a limited set of wells from many possible well paths, and the scheduling of the drilling itself....

Optimal Placing of Wind Turbines: Modelling the Uncertainty

When looking at the optimal place to locate a wind turbine, trade-offs have to be made between local placement and spreading: transmission loss favours local placements and the correlation between the stochastic productions of wind turbines favours spreading. In this paper steps are described to determine the locations of new wind mills that...

Energy management in hybrid electric vehicles: Benefit of prediction

Hybrid vehicles require a supervisory algorithm, often referred to as energy management strategy, which governs the drivetrain components. In general the energy management strategy objective is to minimize the fuel consumption subject to constraints on the components, vehicle performance and driver comfort. Typically, we have to deal with two...

Designing robust road networks: A general design method applied to the Netherlands

Maaike Snelder heeft een ontwerpmethode opgesteld waarmee op basis van expertkennis en geavanceerde modelleringtechnieken kan worden bepaald op welke locaties in het wegennetwerk het best welke robuustheidsmaatregelen kunnen worden getroffen. Voorbeelden van maatregelen zijn het ontvlechten van wegen en het creëren van een samenhangend...

Embedding multiple self-organisation functionalities in future radio access networks

Wireless network operators today allocate considerable manual effort in managing their networks. A viable solution for lowering the manual effort is to introduce self-organisation functionalities. In this paper we discuss the challenges that are encountered when embedding multiple self-organisation functionalities into an overall self...

Stochastic modelling of the ES-2 dummy for robust design

Physical crash test dummies of one type, such as the ES-2 side impact dummy, are not perfectly reproducible due to production and certification tolerances. This means that similar crash tests with various ES2 dummies will have varying results, called experimental scatter. New car designs should be insensitive to this scatter, thus the design is...
