1. Metodologia para implementação de controle supervisório modular local em controladores lógicos programáveis / Methodology for implementation of supervisory control local modular in programmable logic control
Currently, manufacturing automation has assumed an increasingly important role within the industry and the problems of automated control systems have become increasingly complex. Thus, the traditional use of empirical methods heavily base on the experience of the programmer can lead to inappropriate or ineffective solutions. In this case, the Supervisory Con

2. Modelo adaptativo fuzzy genético, preditivo e multiobjetivo para despacho de AGVs
Nos últimos anos, mais empresas aplicam técnicas de automação industrial com o objetivo de aumentar sua eficiência. Cada vez mais Veículos Auto Guiados (AGVs) são usados para tarefa de transporte em indústrias e armazéns. O gerenciamento desses AGVs é a chave para um sistema de transporte eficiente. Um dos principais problemas encontrados no gerenc

3. Programa computacional (PROIRRIGA) para avaliaÃÃo da uniformidade em irrigaÃÃo por gotejamento e sua validaÃÃo
The uniformity in trickle irrigation systems is affected by factors hydraulic, air, lack of maintenance and poor quality of irrigation water resulting in poor distribution of water, either excessive or insufficient, causing loss of productivity. Considering the increased use of automated drip irrigation on farms based on the Family Farm, this work establishe

5. Intelligent systems for welding process automation
This paper presents and evaluates the concept and implementation of two distinct multi-sensor systems for the automated manufacturing based on parallel hardware. In the most sophisticated implementation, 12 processors had been integrated in a parallel multi-sensor system. Some specialized nodes implement an Artificial Neural Network, used to improve photogra

7. Um método para modelagem de controle de AMS usando redes de Petri virtuais / A modeling method for AMS control using virtual Petri Nets
An Automated Manufacturing System (AMS) is a production system where a discrete number of raws is processed and assembled by controlled machines and/or robots. Controlling AMS is a complex task, due to the several sub-systems that compose it and the need for attending strategic production issues and market. The AMS control complexity increases with the neces

8. A Fuzzy classifier model for the production sequencing. / Um método de análise de cenários para sequenciamento da produção usando lógica nebulosa.
Production planning in automated manufacturing environments is a complex task which comprehends, among other activities, the production sequencing. One of the techniques used to determine the best production sequencing is the simulation. All possible sequences can be simulated and, right after that, the sequences with the best performance are verified, accor

10. Sistema interativo de modelagem e simulação de sistemas flexiveis de manufatura-sisma
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 te
