Análise de ferramentas computadorizadas para suporte a modelagem computacional - estudo de caso no domínio de dinâmica dos corpos deformáveis

Abstract

In this work, computer tools are analyzed regarding their support to computational modeling activities. Those tools aim to solve problems such as the lack of reuse of obtained results, the integration of tasks that compound the experiments, and the management of the various steps of the modeling process. The concept \Scientific Workflow" designates the collection of tasks that shapes an experiment in computational modeling. Tools called Scientific Workflow Systems are responsible for automating the execution of these processes. Scientific Workflow Systems are not very spread yet. This is, in part, due to the effort necessary to learn the new techniques involved. Such tools implement a great number of nunctionalities, many of them using recent and unknown technologies to most researchers in computational modeling. This work is intended to provide a detailed study of such functionalities and an evaluation of their applicability to solve the di culties we have mentioned. The approach to carry out the study of functionalities is to build a taxonomy of concepts and functions, in the context of Scientific Workflow Systems. The evaluation of such tools is done by developing a computational modeling case study in the domain of Dynamic Systems, using the Scientific Workflow System named Kepler. The criteria used for choosing this tool will also be discussed. The main aspects of the evaluation are the efficiency in the definition of models and the performance of their execution. To those functionalities that do not couple with our expectations, we will provide developing guides or software artifacts that will improve them.
