Context. The problem of optimal control of flow parameters of a conveyor-type transport system containing sections with reversible conveyors is considered. The object of the stady was an analytical model of a reversible transport conveyor for synthesizing an algorithm for optimal control of the...

While hypothesis testing is a highly formalized activity, hypothesis generation remains largely informal. We propose a procedure that uses machine learning algorithms—and their capacity to notice patterns that people might not—to generate novel hypotheses about human behavior. We illustrate...

The past years have witnessed growing consumer concern about the fairness implications of the widespread adoption of AI in business contexts. To protect consumers against bias from algorithmic service decisions, regulators have introduced legislation holding firms accountable for the fairness of...

In this paper, we study the hierarchical hub network design problem with a ring-star-star structure. In this problem, the hubs are located in two layers. In the first layer, central hubs (main hubs) are located in a ring structure, and in the second layer, secondary hubs are located. Each...

We consider the robust single-source capacitated facility location problem with uncertainty in customer demands. A cardinality-constrained uncertainty set is assumed for the robust problem. To solve it efficiently, we propose an allocation-based formulation derived by Dantzig-Wolfe decomposition...

A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and, as such, is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending attacks. In This paper, we suggest a...

As algorithmic trading (AT) has become a dominant component in financial markets, it is important to understand its benefits and costs. We find that AT is positively related to future stock price crash risk and managers’ bad news hoarding behavior. Additional analyses show that the effect of...
