Supply vessels provide offshore installations with necessary supplies on periodic basis from an onshore base according to weekly sailing plans. Each plan is built for a certain time horizon to guarantee required level of service to offshore installations at least cost. In a sailing plan several voyages are assigned to each vessel. The execution of sailing plans is affected by stochastic weather...

The limited availability of local climatological stations and the limitations to predict wind speed (WS) accurately are significant barriers expansion energy (WE) projects worldwide. A methodology forecast WS at scale can be used overcome these barriers. This study proposes a with high-resolution long-term horizons, which combines Fourier model nonlinear autoregressive network (NAR). Given nonl...

The idea of cyclic scheduling is commonly utilized to address short-term scheduling problems for multiproduct batch plants under the assumption of relatively stable operations and product demands. It requires the determination of optimal cyclic schedule, thus greatly reducing the size of the overall scheduling problems with large time horizon. In this paper a new cyclic scheduling approach is p...

In this paper, we propose an alternative approach to estimate long-term risk. Instead of using the static square root method, we use a dynamic approach based on volatility forecasting by non-linear models. We explore the possibility of improving the estimations by different models and distributions. By comparing the estimations of two risk measures, value at risk and expected shortfall, with di...

This paper uses the term structure of interest rates to explain the variations of stock prices and stock returns. It shows that interest rates have an important impact on stock returns, especially at long horizons. The hypothesis that expected stock returns move one-for-one with ex ante interest rates, which has been rejected in other studies using short horizon nominal asset returns, is suppor...

The angular ADM reduction of the BTZ spacetime yields a Liouvilletype theory. The analysis of the resulting Liouville theory naturally leads to identification of the stretched horizon. The dynamics associated with the stretched horizon has a feature that seems consistent with the unsmooth horizon; the quantum gravity effects are essential for the unsmoothness. We show that the “anomaly” term in...

The short- and medium—long-term effects of management hillside position on soil organic carbon (SOC) changes were studied in a centenary Mediterranean rainfed olive grove. One way to measure these is analyze the quality, as it assesses degradation degree attempts identify practices for sustainable use. In this context, SOC stratification index (SR-COS) one best indicators quality assess from co...

Models for long-term planning often lead to infinite horizon stochastic programs that offer significant challenges for computation. Finite-horizon approximations are often used in these cases but they may also become computationally difficult. In this paper, we directly solve for value functions of infinite horizon stochastic programs. We show that a successive linear approximation method conve...
