Data Science for Massive (Dynamic) Networks

Venue: University of Strathclyde, Room: TBA
Speaker: Panos M. Pardalos
Date: Friday, 10 July 2015 at 14:00 - 15:00

Registration: Please email ashwin.arulselvan@strath.ac.uk or register at eventbrite before 15th May 2015 for a guaranteed spot. This is just before Euro 2015 at Strathclyde; so places may be limited.

Data science tools, such as data mining and optimization heuristics, have been used
to analyze many large (and massive) data-sets that can be represented as a network. In these
networks, certain attributes are associated with vertices and edges. This analysis often provides
useful information about the internal structure of the data-sets they represent. We are going to
discuss our work on several networks from telecommunications (call graph), financial
networks (market graph), social networks, and neuroscience.
In addition, we are going to present recent results on critical element selection. In network
analysis, the problem of detecting subsets of elements important to the connectivity of a
network (i.e., critical elements) has become a fundamental task over the last few years.
Identifying the nodes, arcs, paths, clusters, cliques, etc., that are responsible for network
cohesion can be crucial for studying many fundamental properties of a network.

 


The Impact of Pricing Decisions in a Business-to-Business environment

Venue: Playfair Library, Old College, South Bridge EH8 9YL Edinburgh
Speaker: Christopher S. Tang
Date: Friday, 17 July 2015 at 14:00 - 15:30

Free registration here. 

Abstract: We examine the impact of pricing decisions in a B2B environment.  Because the scope is broad and relevant literature is scant, we shall examine this issue in two specific setting.  We first examine how discount pricing concessions can create the “bullwhip effect” in the MRO (maintenance, repair, and operations) industry and discuss how to mitigate the bullwhip effect.  Then, we discuss how uncertain spot price market in the ocean freight industry has triggered customers to demand carriers to offer “price matching.”  We examine the impact of price matching mechanism on the carrier.
