1. A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems. A

2. DETERMINING PRODUCTION AND INVENTORY PARAMETERS: AN INTEGRATED SIMULATION AND MAVT APPROACH WITH TRADEOFF ELICITATION
ABSTRACT This study puts forward a multi-attribute decision model that determines good production and inventory parameter settings in make-to-stock (MTS) environments controlled by the Conwip (constant work-in-process) method. This model uses a discrete event simulation to evaluate the performance of a system in relation to work-in-process and a finished goo

3. DECISION WITH ARTIFICIAL NEURAL NETWORKS IN DISCRETE EVENT SIMULATION MODELS ON A TRAFFIC SYSTEM
ABSTRACT This work aims to demonstrate the use of a mechanism to be applied in the development of the discrete-event simulation models that perform decision operations through the implementation of an artificial neural network. Actions that involve complex operations performed by a human agent in a process, for example, are often modeled in simplified form w

4. ANALYSIS OF SHIP ARRIVAL FUNCTIONS IN DISCRETE EVENT SIMULATION MODELS OF AN IRON ORE EXPORT TERMINAL
ABSTRACT This work evaluates the results of different distribution functions of ships arrivals in the simulation of an iron ore export terminal under implementation. The system adopted for the analysis applied a real case designed for installation of a Brazilian company terminal. The analysis was carried out by a discrete event simulation model. Variations o

6. 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

8. Development of a discrete event simulation Kernel for manufacturing systems with 3D visualization / Desenvolvimento de um núcleo de simulador de eventos discretos para sistemas de manufatura com visualização 3D
The need of knowledge and control of the manufacturing environment is continuously growing. Over the last century and the beginning of this, several tools and procedures were designed in order meet those necessities. Among them, simulation is a decision support tool widely used, mainly in the manufacturing industry. Virtual reality can be used in those simul

9. Controle supervisÃrio da cadeia produtiva do biodiesel da mamona baseado em redes de Petri / Supervisory control of castor bean biodiesel suppy chain based on Petri nets
Nowadays many countries present critical problems related to energy demand-supply equilibrium. The reserves of petroleum-based products are unable to face future demand for the next decades. So, the search for alternative sources of energy has been strongly directed to biodiesel. Several fruit oils can be used as a source for biodiesel production and the cas
