The Analysis and Evaluation of Differentiated Transit Fare Structures
TL;DR: A bi-level programming model is presented to evaluate the differentiated transit fare structures, which aims to minimize passengers’ total travel cost and is a stochastic user equilibrium transit assignment model with capacity constraints.

Model and algorithm for a liner ship fleet planning problem with uncertain container shipment demand
Abstract: This paper deals with a short-term liner ship fleet Planning (LSFP) problem with container shipment demand uncertainty. Assuming that container shipment demand between any two ports on each ship route follows a normal distribution, this paper develops an integer linear programming model with chance constraints for the LSFP problem and proposes a two-phase heuristic algorithm for solving the large-scale LSFP instances. Finally, numerical examples are used to show application of the proposed model and evaluate the performance of the two-phase heuristic algorithm.

TL;DR: In this paper, the authors investigated varying confidence in a pure subjective judgment task, and how this confidence was predicted by pre-stimulus alpha oscillations, and revealed a specific pathway underlying such linkage.
