Networks are the backbone of modern HPC systems. They serve as critical infrastructure, tying together applications, analytics, storage and visualization. Despite this importance, we have not fully explored how evolving communication paradigms and network design will impact scientific workloads. As networks expand in the race towards Exascale, a principled approach should be taken to reexamine ...

However, what constitutes good practice or bad solutions depends on the context. Therefore, there is no definite recipe for success. In this paper, the emphasis is on high quality public transport that is able to replace car use as a significant measure to create a more sustainable and environment friendly city region on a long-term basis. In most urban regions in the developed world, this is a...

This paper proposes a practical methodology for the problem of designing a metro configuration under two criteria: population coverage and construction cost. It is assumed that a set of corridors defining a rough a priori geometric configuration is provided by the planners. The proposed algorithm consists of fine tuning the location of single alignments within each corridor. This is achieved by...

In a circular city model, I consider network design and pricing decisions for a single fast transport connection that faces competition from a slower but better accessible transport mode. To access the fast transport network individuals have to make complementary trips by slow mode. This fact has interesting implications on the location decisions. I show that in the presence of competition the ...

Infrastructure networks – in communication and transport – are a key feature of an economy. The functionality of these networks depends on the connectivity and sizes of different components. However, these networks face a variety of threats ranging from natural disasters to intelligent attacks (carried out by human agents). How should networks be defended and designed to ensure connectivity? We...

In this paper, we study the network design problem with relays considering network survivability. This problem arises in telecommunications and logistic systems. The design problem involves selecting two edge-disjoint paths between source and destination node pairs and determining the location of the relays in the network to minimize the network cost. A constraint is imposed on the distance tha...

Conceptual aircraft design and the network routes that they travel on are inextricably linked to passenger driven demand. Decisions made in the acquisition and subsequent allocation of aircraft assets to serve chosen links translate to latent passenger observations of ticket pricing and routes served between origin-destination (OD) pairs. It is proposed that such latency gives rise to a reflexi...

Abstract – Brain-Like Stochastic Search (BLiSS) refers to this task: given a family of utility functions U(u,), where  is a vector of parameters or task descriptors, maximize or minimize U with respect to u, using networks (Option Nets) which input  and learn to generate good options u stochastically. This p...

Effective supply chain distribution network design needs to consider various performance dimensions and product characteristics. Recently, researchers have begun to realize that the decision and integration effort in supply chain design should be driven by a comprehensive set of performance metrics and also product characteristics. In this paper, we relate product characteristics to optimizing ...
