  • Miguel A. Garay Garcell, Marcello Sandi Pinheiro, Vanessa Teixeira Sandi Hierarchical Multilevel Approach in Hypermedia Intelligent Systems for Mathematical Modeling // Scientific article. Journal "Transactions of the TSTU", vol. 08 , Tambov. TSTU publisher house , 2002. (pdf-file)
    Abstract: Since ancient times, models have become widely accepted as a means for studying phenomena, but the processes involved in the mathematical modeling formulation continue being complex and ill-structured problem. For many years Methodologies of mathematical modeling have tended to concentrate the effort on taxonomies more than to the formulation stage of the modeling process. At the present paper, the analysis and formulation modeling stage are discussed. In this relation, a new method for problem solving based on a Hypermedia Intelligent Tutoring System is proposed. The system acts like a tutor helping students to model and solve optimization problems under complex decisional situations. In this connection, the Systems Theory and its methods for the HITS design are implemented. The system was implemented in C++ and Delphi on microcomputer.
  • Miguel A. Garay Garcell, Marcello Sandi Pinheiro, Vanessa Teixeira de Oliveira Sandi Clustering and Making Decisions Methods for Intelligent Systems // Scientific article. Journal "Transactions of the TSTU", vol. 08 , Tambov. TSTU publisher house , 2002. (pdf-file)
    Abstract: The processes involved in the classification of objects and word problems continue being a complex and ill-structured problem. In this paper, a software tool for Hypermedia Intelligent Tutoring Systems is proposed. This tool helps us to define the complexity levels for a set of proposed problems to students. In this way, the intelligent systems designers and professors can use it to organize the problem base. On the other hand, this tool constitutes an important element during training and learning process because it permits to organize the transit from simple to complex in problem solving. It uses different methods of classification, like as statistical methods, experts’ proofs and others. The evaluations of parameters can involve objective and subjective elements. In this relation, a particular version of Delphi Method is developed. The system was implemented on Delphi 4.0 for Windows.
