1. Production line performance analysis within a MTS/MTO manufacturing framework: a queueing theory approach
Abstract Paper aims Mixing the Make-To-Stock (MTS) and Make-To-Order (MTO) strategies to benefit from the both manufacturing systems in an environment with impatient customers. Originality This is the first research article which uses the queuing theory to find the best place of the Order Penetration Point (OPP) in a production line with impatient custom

2. Desenvolvimento de um ambiente para simulação da manufatura baseado em features e realidade virtual / Development of environment for simulation of manufacturing based on features and virtual reality
Nowadays with the diversification of products demanded, manufacturing systems have become increasingly complex and with difficult operation. Hardly the person responsible for the manufacturing area has all the information necessary to anticipate the details for their implementation. On the other hand, companies don\ t have the time or resources to test alter

3. Arquitetura escalável de alto desempenho para atualização, acesso e recuperação de informações em bancos de dados de aplicações embarcadas
O gerenciamento remoto de múltiplos sistemas tais como máquinas operatrizes, veículos, aviões, dentre outros, demanda um fluxo bastante intenso de dados entre eles e o sistema gerenciador. Pesquisas têm sido desenvolvidas na concepção e implementação de arquiteturas escaláveis que atendam essas demandas levando a questões interessantes de desempen

4. Um estudo de métodos de solução do modelo hipercubo de filas para sistemas de grande porte / A study of hypercube queueing model solution methods for large scale systems
The planning of public and private service systems is essential to assure the quality of the services realized by these systems. A model that has been widely used for planning server-to-customer service systems is the Hypercube Queueing model. The Hypercube Queueing model is an analytical stochastic model that allows the evaluation of different configuration

5. Data traffic dimensioning for 1xEV-DO cellular systems. / Dimensionamento de tráfego de rede de dados para sistema celular 1XEV-DO.
Research regarding voice and data dimensioning models applied to Telecommunication Networks. For circuit switched voice networks dimensioning, the Erlang formulas are used. When it comes to newer data networks, a packet based dimensioning is required, and the complexity is significantly increased due to the diversity of applications and its multiple features

6. Otimização da configuração e operação de sistemas médicos emergenciais em rodovias utilizando o modelo hipercubo.
The purpose of this study is to develop effective methods to analyze the configuration and operation of the emergency medical systems (EMS) on highways. Due to the stochastic nature of these systems, especially in the arrival and assistance processes of the emergency calls, we apply the Hypercube Queuing Model to evaluate the performance measures of the syst

8. Self-organized queuing and scale-free behavior in real escape panic
Numerical investigations of escape panic of confined pedestrians have revealed interesting dynamical features such as pedestrian arch formation around an exit, disruptive interference, self-organized queuing, and scale-free behavior. However, these predictions have remained unverified because escape panic experiments with real systems are difficult to perfor
