This paper describes a methodology based on 40 criterions as well as a mixture of MCDM methods to evaluate different technologies applied in modern training systems. The criterions are grouped in a threedimensional (3D) model in accordance with their use and application in training processes. The proposed 3D model includes the Management (M), the(More)
The number of elderly and chronically ill patients has grown significantly over the past few decades as life expectancy has increased worldwide, leading to increased demands on the health care system and significantly taxing traditional health care practices. Consequently, there is an urgent need to use technology to innovate and more constantly and(More)
It is well known that personalized tutoring helps to improve the learning process and to obtain better results. With this aim we are developing a model including the learning styles of the students. We based our model on the Felder-Silverman Learning Styles Model. According to the student learning style, the instruction is established by a proposed set of(More)
The traditional approach for comparing heuristic algorithms uses well-known statistical tests for meaningfully relating the empirical performance of the algorithms and concludes that one outperforms the other. In contrast, the method presented in this paper, builds a predictive model of the algorithms behavior using functions that relate performance to(More)
As the use of web grows, organizations are increasingly choosing to use it to provide their services. The modeling process is a previous step in the systematization of a process. Due to the great number of modeling tools in existence, it is necessary to identify the information that tools allow to specify. A set of concepts is proposed to evaluate modeling(More)
