RESUMO

Inside the current complexity of the highly automated, computer-controlled manufacturing systems, even the most careful analytical planning sometimes fails to prevent major blunders. This fact has caused organizations to increasingly turn to simulation for dynamic analysis of these systems prior to any implementation. However, simulation modelling studies tend to be a low productivity work, consuming a great deal of time and effon. Most of the times, the computer is used mainly for execution of the model, while construction, design of experiments and analysis of results are shouldered by the user. These facts are ones of the main motivations of research activities on simulation. In this work, a modelling and simulation software applied to flexible manufacturing systems and specially designed to non-programmer users is described. The software is an integrated modelling, simulation and analysis system with a graphic user-friendly interface. It has a schematic capture editor for cell layout description, animation of simulation performance, statistical analysis, mouse suppon and context sensitive help. The design and implementation of the system were based on the object-oriented paradigm. The elements available for building a manufacturing cell were implemented as autonomous objects which communicate through message passing. Operations sequencing control is performed by a dedicated simulation kemel. The system was written in Object-Oriented Turbo Pascal and runs under DOS on PC-compatible microcomputers. Tests were performed with a printed circuit board assembly application. Results have shown that the implemented prototype can be improved in order to be used as a powerful tool in industrial applications Resumo Abstract
