Abstract. In this research we try to consider the problem of applying the Nonhomogeneous Poisson process to trends of economic development. More specifically, a modified Nonhomogeneous Poisson process is derived when the intensity rate is considered as a solution of stochastic differential equation which satisfies the geometric Brownian motion. The mean and the variance of the modified process ...

Ethanol is mainly produced from sugar cane (Brazil) and corn or other cereals (US), but these sources induced criticisms as for social sustainability, being directly competitive with the food and feed chain. Therefore, a second generation concept was introduced for biofuels, by developing processes for their production from waste biomass or energy crops not competitive with agriculture. However...

Since little attention has been devoted to multiattribute control charts in the literature, in this research a new methodology is developed to employ the multivariate exponentially weighted moving average (MEWMA) chart for multiattribute processes. Moreover, since the variable sample size and sampling interval (VSSI) MEWMA charts detect small process mean-shifts faster than the traditional MEWM...

This article presents a short review of dual-process and dual-system theories from social and cognitive psychology and comments on their relevance for research on economic behavior. We view dual-process theories as a theoretical scaffolding which helps structure and interpret experimental results and can deliver important insights on human behavior in economic contexts. Dual-process ideas and c...

For effective decision making, individuals must be able to form subjective values from many types of information. Yet, the neural mechanisms that underlie potential differences in value computation across different decision scenarios are incompletely understood. Here, we used functional magnetic resonance imaging (fMRI), in conjunction with the machine learning technique of support vector machi...

Knowledge management often generates theories that are too general or abstract to be easily testable. In some cases, simulation modeling can help. In this paper we develop an agent based simulation model derived from a conceptual framework, the Information Space or ISpace and use it to explore the differences between a neoclassical and a Schumpeterian information environment. After introducing ...

Although the importance of flexibility has long been recognized in the service industry, scholars and practitioners alike still struggle to express the value of flexible services in economic terms. We perceive that many service providers tend to strive for very flexible service processes no matter in which ecosystem they are embedded. They invest huge amounts of money in flexibilization project...

We review some approaches to the understanding of fluctuations in some models used to describe socio and economic systems. Our approach builds on the development of a simple Langevin equation that characterises stochastic processes. This provides a unifying approach that allows first a straightforward description of the early approaches of Bachelier. We generalise the approach to stochastic equ...

The article discusses building models based on the reconstructed attractors of the time series. Discusses the use of the properties of dynamical chaos, namely to identify the strange attractors structure models. Here is used the group properties of differential equations, which consist in the symmetry of particular solutions. Examples of modeling engineering systems are given.
