A major reason behind crowding in emergency departments (ED) is non-urgent patients' visits to ED. In this paper we investigate how non-urgent ED visits are influenced by patients' imperfect perception of their urgency and their self-interested choice, and we explore interventions that can...

This paper analyses the decision-making processes of heterogeneous agents, when both individual preferences and group actions are taken into account. Under the assumptions of certain topologies of interactions and assuming cognitive and informational restrictions, an agent-based model is...

The technologically intensive nature of the predictive maintenance (PdM) method restricts its use to companies with higher turnover. This research is aimed to propose a PdM model for an N-component repairable system by integrating non-homogeneous Poisson process (NHPP) models and a system...

This paper proposes a predictive maintenance policy using modified failure mode effect and criticality analysis (Mod-FMECA) technique. FMECA is used to identify failure modes, reasons, effects and criticality of the system (machine/plant) but in Mod-FMECA in addition to the analysis carried for...

It is a stylized fact of formal mathematical modeling that a 'space' cannot be described by attempts at parameterization of distances or areas (under or above curves) that feasibly could occur within the space. Tools for parameterization of mathematical spaces, such as Set Theory, Connectedness,...

Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition,...

We build an analytical framework to model the strategic interactions between a firm and hackers. Firms invest in security to defend against cyber attacks by hackers. Hackers choose an optimal attack, and they share information with each other about the firm's vulnerabilities. Each hacker prefers...

The complexity of the world oil market has increased dramatically in recent years and new approaches are needed to understand, model, and forecast oil prices today. Many models have been explored and most of the papers and modeling projects referenced in this paper identify their own...

This paper presents a mathematical model to evaluate the risks of arbitration in contractual disputes to decide whether or not to raise an arbitration case for a claim. It adds the ingredient of a regret theory approach for taking that decision, if an amicable settlement amount is not agreed....

We develop a nonparametric approach to test for monotone behavior in optimizing agents and to make out-of-sample predictions. Our approach could be applied to simultaneous games with ordered actions, with agents playing pure strategy Nash equilibria or Bayesian Nash equilibria. We require no...
