The Minimum Circuity Frontier and the Journey to Work

Levinson, David; El-Geneidy, Ahmed - Networks, Economics and Urban Systems Research Group … - 2007

In an urban context people travel between places of residence and work destinations via transportation networks. Transportation studies that involve measurements of distances between residence and work locations tend to use Euclidean distances rather than Network distances. This is due to the...

Network architecture, barter exchange and the diffusion of ideas

Cowan, Robin; Jonard, Nicolas - In: International Journal of Agricultural Resources, … 6 (2007) 2, pp. 165-178

We model knowledge diffusion as agents exchanging ideas through a barter process. The model builds on empirical observations of informal knowledge trading among competing agents. The process takes place on a network substrate in which agents are nodes, and can trade only with those to whom they...

Optimizing complex networks for resilience against cascading failure

Ash, J.; Newth, D. - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 673-683

Our modern society has come to depend on large-scale infrastructure networks to deliver resources to our homes and businesses in an efficient manner. Over the past 10years there have been numerous examples where a local disturbance has lead to the global failure of systems. In this paper, we use...

Peer Effects and Social Networks in Education and Crime

Calvó-Armengol, Antoni; Patacchini, Eleonora; Zenou, Yves - C.E.P.R. Discussion Papers - 2005

This paper studies whether structural properties of friendship networks affect individual outcomes in education and crime. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Bonacich centrality measure....

Safety Stock Positioning in Supply Chains with Stochastic Lead Times

Simchi-Levi, David; Zhao, Yao - In: Manufacturing & Service Operations Management 7 (2005) 4, pp. 295-318

We study the safety stock positioning problem in single-product multistage supply chains with tree network structures, where each stage controls its inventory using an installation continuous-time base-stock policy. External demands follow independent Poisson processes, and unsatisfied demands...

Social network structure and performance of improvement teams

Luo, Jar-Der - In: International Journal of Business Performance Management 7 (2005) 2, pp. 208-223

There is a kind of knowledge, possessed by groups, that is more than the aggregation of individual knowledge. Nahapiet and Ghoshal call it intellectual capital. How does social structure, in a project team, influence collective knowing capability? In this study, several conclusions are made....

Local Network Effects and Network Structure

Sundararajan, Arun - EconWPA - 2004

This paper presents a model of local network effects in which agents connected in a social network each value adoption by a heterogeneous subset of others, and have incomplete information about the structure and strength of adoption complementarities between all other agents. I show that the...

Impact of network structure on the capacity of wireless multihop ad hoc communication

Krause, Wolfram; Glauche, Ingmar; Sollacher, Rudolf; … - In: Physica A: Statistical Mechanics and its Applications 338 (2004) 3, pp. 633-658

-critical-node effect the end-to-end throughput capacity sensitively depends on the underlying network structure, resulting in differing … way. A performance indicator is the end-to-end throughput capacity. Various models, generating differing ad hoc network … structure via differing transmission power assignments, are constructed and characterized. They serve as input for a generic …
