Abstract: Model design and implementation by means of computer technology and methods has been a fo-cus of multiple researches in Artificial Intelligence, Operations Research, Decision Support and Management Sys-tems at the last years. Case based reasoning techniques and methods are used frequently in problem solving. They help model builders to identify and design optimization models improving their cognitive skills and knowledge in modeling process. At the present paper, it is proposed a new approach based on application of case based reasoning in model building. The problems associated to construction of optimization models by means of computer are dis-cussed from theoretical and practical point of views. Finally, a new intelligent system is proposed and described. It has as objectives to help professional (specialists, professors, students and others) in model building and implemen-tation on Internet. The fast rise of information and telecommunication networks, and particularly Internet and its rapid diffusion, implementation and introduction into universities, professional training and postgraduate institu-tions, have highlighted the need to define the most effective ways of realizing the teaching and learning potential. Electronic learning (e-Learning) as it has come to be known, makes use of the Internet and digital technologies to deliver instruction synchronously or asynchronously to anyone who has access to a computer and an Internet con-nection. Taking into account this reality and necessity it was proposed a new e-learning platform for Operations Research’s teaching and learning. The system has been implemented in .net technology using C# computer lan-guage and web services. At the present time, it has been testing and improving at Havana Institute of Technology.
