This study aims to develop a novel methodology to prioritize the construction of new railway infrastructures for privatization. The private sector can cooperate to solve the capacity problems of railway networks, by the construction of new infrastructure. The purpose of this study is to answer the basic question that whether the capacity problems of the railway networks can be solved simply by ...

Capacity drop (CD) at overloaded bottlenecks is a puzzling traffic flow phenomenon with some internal and complicated mechanisms the microscopic level. not only important for theory modelling, but also significant control. A model evaluating control measures needs to be able reproduce capacity in order deliver reliable evaluation results. This paper delivers comprehensive overview on subject fr...

What is the time course of visual attention? Attentional blink studies have found that the 2nd of 2 targets is often missed when presented within about 500 ms from the 1st target, resulting in theories about relatively long-lasting capacity limitations or bottlenecks. Earlier studies, however, reported quite the opposite finding: Attention is transiently enhanced, rather than reduced, for sever...

ATM supports multiple quality of service classes for different application requirements. A Quality of Service is associated with a virtual path connection. Dynamic reconfiguration can generate an optimal virtual path connection network and maintains sufficient capacity to carry the established calls in progress. We developed a tool to present information specific to the changes of virtual path ...

The lot-sizing and production scheduling problem in a real-life multi-product yoghurt production line is addressed. A new discrete/continuous time representation mixedinteger linear programming model, based on the definition of families of products, is presented. It is mainly optimized the packaging stage while timing and capacity constraints are imposed with respect to the pasteurization/homog...

Today, various structural and non-structural solutions are used to control and reduce the negative effects of floods in investigation and executive projects. But what is certain is that the optimal solution to minimize flood damage is a combination of structural and non-structural methods (planning and response measures). It is essential to provide these solutions in a metropolis like Tehran be...

An explicit rate switch scheme monitors the load at each link and gives feedback to the sources. We define the overload factor as the ratio of the input rate to the available capacity. In this paper, we present three overload based switch schemes which provide MCR (minimum cell rate) guarantees for the ATM (asynchronous transfer mode) ABR (available bit rate) service. The switch schemes propose...
