Abstract The rotating shallow water model is a simplification of oceanic and atmospheric general circulation models that are used in many applications such as surge prediction, tsunami tracking ocean modelling. In this paper we introduce class which stochastically perturbed order to incorporate uncertainty into the underlying system. stochasticity chosen judicious way, by following principles l...

We consider the problem of preparing for a disaster season by determining where to open warehouses and how much relief item inventory preposition in each. Then, after each disaster, prepositioned items are distributed demand nodes during post-disaster phase, additional procured as needed. There is often uncertainty level, affected areas’ locations, items, usable fraction post-disaster, procurem...

In this article we give theoretical results for different stochastic orders of a log-scale-location family which uses Tsallis statistics functions. These describe the inequalities moments or Gini index according to parameters. We also compute mean in case q-Weibull and q-Gaussian distributions. The paper is aimed at analyzing order between survival functions, Lorenz curves (as consequences) tog...

The multi-armed bandit problem forms the foundation for solving a wide range of on-line stochastic optimization problems through a simple, yet effective mechanism. One simply casts the problem as a gambler that repeatedly pulls one out of N slot machine arms, eliciting random rewards. Learning of reward probabilities is then combined with reward maximization, by carefully balancing reward explo...

an integrated model considers all parameters and elements of different deficiencies in one problem. this paper presents a new integrated model of a supply chain that simultaneously considers facility location, vehicle routing and inventory control problems as well as their interactions in one problem, called location-routing-inventory (lri) problem. this model also considers stochastic demands ...
