The estimation of risk measures recently gained a lot of attention, partly because of the backtesting issues of expected shortfall related to elicitability. In this work we shed a new and fundamental light on optimal estimation procedures of risk measures in terms of bias.We show that once the...

We propose a new backtesting framework for Expected Shortfall that could be used by the regulator. Instead of looking at the estimated capital reserve and the realised cash-flow separately, one could bind them into the secured position, for which risk measurement is much easier. Using this...

In this paper we provide a unified and flexible framework for study of the time consistency of risk and performance measures. The proposed framework integrates existing forms of time consistency as well as various connections between them. In our approach the time consistency is studied for a...

We propose a new class of mappings, called Dynamic Limit Growth Indices, that are designed to measure the long-run performance of a financial portfolio in discrete time setup. We study various important properties for this new class of measures, and in particular, we provide necessary and...

It is shown that the the popular least squares method of option pricing converges even if the underlying is non-Markovian, the pay-offs are path dependent and with a very flexible setup for approximation of conditional expectations. The main benefit is the increase of freedom in creating...

In this paper we provide a mathematical illustration to an empirical fuzzy phenomena known as 20-60-20 rule. In particular we show that if a random vector follows multivariate normal distribution and we split the whole population into three groups, then this fixed ratio leads to a global...

Fourth Industrial Revolution or Industry 4.0 denotes a fundamental change on how production and business in general is perceived and organized. This paper questions the role of logistics within this context and raises a claim for a central role in future. It is a revision of a current position...

Decentral production control plays a crucial role within the paradigm of Industry 4.0. Due to the fast and flexible decisions on allocation and sequencing required by this type of control, there is no baseline production schedule in advance. This creates a dilemma for efficient staff deployment...

With the application of in-house logistics automated guided vehicle (AGV) systems for transportation three different control problems arise: task assignment, empty vehicle balancing and routing. With an increasing fleet size and especially when considering requirements like flexibility and...
