Future Meetings

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 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.

Tutorial on Vehicle Routing

Venue: Project Room 1.06, 50 George Square, Edinburgh EH8 9LH
Speaker: Gilbert Laporte
Date: Monday, 07 September 2015 at 08:30 - 17:30

The operational management of fleets of vehicles in many application areas including the transportation of merchandise and the provision of public services such as waste collection is increasingly challenging with the rise of big data and smart online retailing systems amongst other things. Planners and schedulers of transportation routes for vehicles are often faced with many practical challenges including the combinatorial nature of routing and scheduling problems. Although significant progress has been made on the design of computationally efficient optimal methodologies and algorithms, it remains that the sizes of the problems to be solved in practice tend to favour the use of heuristics approaches and methods.

This World Class Workshop attempts to open the black box of exact and heuristic solution methods for both node and arc routing problems. The objective of this workshop is to enhance our understanding of why certain solution approaches and methods perform very well in some cases, but behave poorly in others. It should also initiate the discussion on future research directions by looking at a number of past and present-day problems. The workshop is primarily designed for researchers (e.g. PhD students, post-docs, and faculty members) in the fields of routing, scheduling and logistics.

This workshop is delivered by a renowned expert Professor Gilbert Laporte from the CIRRELT Research group, to present recent research on routing problems with applications in the area of transportation.
