Engenharia de Automação
A vazão, medida através de um sensor do tipo placa de orifício que fornece valores contínuos da grandeza medida, deve ser monitorada numa planta industrial. O projeto deve medir a vazão em 19 pontos distintos e verificar o estado de 15 sensores de fim de curso que fornecem os valores discretos verdadeiro e falso. O orçamento é limitado de forma que se deve comprar o mínimo necessário de equipamentos para o projeto. Sabe-se que um CLP será utilizado para o monitoramento e que cartões de aquisição de dados analógicos (CA) para esse CLP são mais caros que cartões de entradas digitais (CD).
Considerando-se que cada cartão tem 8 entradas, o número de cartões CA e CD, que atendem aos requisitos técnicos e de orçamento, são

Engenharia de Automação
Equipamentos modernos são conectados em redes e transmitem tanto sinais de entradas e saídas digitais como sinais analógicos e diagnósticos, oferecendo opções de redes para controle e monitoramento desde níveis gerenciais até o chão de fábrica. Muitos fios e mangueiras são necessários para ligação dos diversos componentes nesse tipo de controle. A junção de válvulas eletromagnéticas com unidades de entradas e saídas de sinais digitais e analógicas, associada a um controlador, reduz consideravelmente as quantidades de mangueiras e fios permitindo um manuseio mais fácil e econômico, além de facilitar a manutenção. Essa junção combina, em um só elemento, os universos da pneumática, elétrica e redes.

Model copes with chaos to deliver relief
Computer program helps responders transport
supplies in tough conditions
By Rachel Ehrenberg Science News, Web edition: Monday, February 21st, 2011
WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.

The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.
