Web site usability is a critical metric for assessing the quality of a firm’s web presence. A measure of usability must not only provide a global rating for a specific web site, ideally it should also illuminate specific strengths and weaknesses associated with site design. In this paper we...

We investigate an online edge-weighted bipartite matching problem with general capacity constraints. In this problem, the resources are offline and non-replenishable with different capacities. Demands arrive online and each requests a certain amount of resources. The goal is to maximize the...

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...

This article introduces two sequential heuristics that are designed to overcome some of the practical limitations of the Entropy Pooling (EP) method. Both of these heuristics repeatedly apply the original EP method to sequentially arrive at the posterior probability and usually lead to...

The paper investigates how the availability heuristic of individual stocks affects equity returns, where the availability heuristic is measured by the irrational signal in the fractal dimension. Our evidence support that the availability heuristic can positively predict the short-term expected...

The primary objective of this paper is to provide small retail traders with a heuristic model in the form of a derivative trading strategy. It is an effort to design an easy and effective derivative trading strategy for retail traders who often lose money in the stock market as a result of...

Using micro data on managerial expenditures, we uncover heuristics in capital budgets, such as nominal rigidity, anchoring, and sharp reset deadlines. Such heuristics engender managerial opportunism and erode investment efficiency. Managers with a budget surplus increase investment sharply...
