Quantitative models and software architecture, facing student Desertion and Permanence
The development of multi-tier architecture based on knowledge and model driven for the competitiveness is discussed in Higher Education; the engine are Mathematical and Computational Models for dynamic and structural analysis of the academic governance given the student high dropout. The problem is characterized by the high social and economic costs; the layers mentioned, mainly are: Institution issues, Users (3-student levels, Faculty Teachers and Parents) and the data and knowledge, enabling management of multiple piece inter-connected environments, focusing on the governance with its sustainability impact into quality, productivity and competitiveness. Data architecture gives several figures on desertion, costs (families, institutions). The period of observation, the student's retention figures were increased significantly and the desertion control was also improved.
Handbook on Enterprise Architecture
This handbook is about methods, tools and examples of how to architect an enterprise through considering all life cycle aspects of Enterprise Entities.Itis based on ISO15704:2000, or the GERAM Framework.A wideaudience is addressed, as the handbook covers methods and tools necessary to design or redesign enterprises, as well as those necessary to structure the implementation into manageable projects.
Solving fuzzy equations in economics and finance
Abstract In this paper we apply our new solution procedure for solving fuzzy equations (linear, non-linear, differential) to three problems in economics and finance. The three applications are: (1) Leontief's input-output model; (2) the internal rate of return; and (3) a dynamic supply-demand model where price and supply are governed by a system of differential equations.
