Mitigating the adverse effects of uncertainty in appointment systems, arising from heterogeneous patient needs and preferences, is critical to the effective use of scarce medical resources and patient satisfaction. This study addresses an online scheduling problem with multiple servers and...

Information and communication technologies (ICT) for health or eHealth solutions hold great potential for generating systemic efficiencies by strengthening five critical pillars of a health system: human resources for health, supply chain management, health care financing, governance and service...

The objective of this study is to evaluate the costs and benefits of different demand risk sharing rules for road infrastructure concessions, from the point of view of the economic attractiveness of the projects for the concessionaire and the price reduction for users. The traffic trajectory of...

In this paper, we explore a dynamical version of by Aoki and Yoshikawa model (AYM) for an economy driven by demand. We show that when an appropriate Markovian dynamics is taken into account, AYM has different equilibrium distributions depending on the form of transition probabilities. In the...

In this paper, the authors explore a dynamical version of the Aoki and Yoshikawa model (AYM) for an economy driven by demand. They show that when an appropriate Markovian dynamics is taken into account, the AYM has different equilibrium distributions depending on the form of transition...

This paper investigates the conditions under which a dynamic, stochastic macroeconomic model with many interacting agents will exhibit the ‘small shocks, large shocks’ property that is often said to characterize observed time series: small shocks have a transient impact on the system,...

This paper presents a new stochastic multidimensional scaling procedure for the analysis of three-mode, three-way pick any/ J data. The method provides either a vector or ideal-point model to represent the structure in such data, as well as “floating” model specifications (e.g., different...

In this paper we review some applications of the path integral methodology of quantum mechanics to financial modeling and options pricing. A path integral is defined as a limit of the sequence of finite-dimensional integrals, in a much the same way as the Riemannian integral is defined as a...
