With the increase of offshore wind farm size, use classical analytical reliability methods becomes computationally intractable. This paper proposes a holistic approach combining multi-state Markov processes and universal generating function for availability assessment radial large-scale farms. The proposed model combines turbine output, reliability, inter-array cable models to assess output at ...

Stochastic programming problems with simple recourse belong to problems depending on a random element only through the corresponding probability measure. Consequently, this probability measure can be treated as a parameter of the problem. In this paper the stability with respect to the above mentioned parameter will be studied for generalized simple recourse problems.

Abstract Geotechnical structures are being increasingly employed, in Europe as all around the world, to exchange heat with ground and supply thermal energy for heating cooling of buildings de-icing infrastructure. Most current practical applications related piles, but embedded retaining walls now also adopted. However, analysis design methods these new dual use foundations exchangers currently ...

Co-production systems, in which multiple products are produced simultaneously in a single production run, are prevalent in many industries. Such systems typically produce a random quantity of vertically differentiated products. This product hierarchy enables the firm to fill demand for a lower-quality product by converting a higher-quality product. In addition to the challenges presented by ran...

Stochastic optimization, especially multistage models, is well known to be computationally excruciating. In this paper, we introduce the concept of semi-complete recourse in the context of stochastic programming as a less restrictive condition compared to complete recourse and propose methods for approximating multistage stochastic programs with risk constraints and semi-complete recourse. We e...

The influence of lattice-melt-induced resistivity gradients on the transport of mega-ampere currents of fast electrons in solids is investigated numerically and experimentally using laser-accelerated protons to induce isochoric heating. Tailoring the heating profile enables the resistive magnetic fields which strongly influence the current propagation to be manipulated. This tunable laser-drive...

in his collection north, heaney mythologizes the contemporary history of the people of northern ireland through conflating the mythological history of the people of ireland, with the 1960s troubles in northern ireland. used by the modernist poets, the method of representing the contemporary history through recourse to mythology have been also favored by poets who have experienced colonial and p...

We consider the online MST and TSP problems with recourse. The nodes of an unknown graph with metric edge cost appear one by one and must be connected in such a way that the resulting tree or tour has low cost. In the standard online setting, with irrevocable decisions, no algorithm can guarantee a constant competitive ratio. In our model we allow recourse actions by giving a limited budget of ...

Mixed-integer two-stage stochastic programs with fixed recourse matrix, random recourse costs, technology matrix, and right-hand sides are considered. Quantitative continuity properties of its optimal value and solution set are derived when the underlying probability distribution is perturbed with respect to an appropriate probability metric.
