Prof. Guy Latouche

Guy Latouche received the Ph.D. degree in Mathematics from the Université Libre de Bruxelles (ULB) in 1976.  He has mostly taught classes on stochastic processes and their applications at ULB, and he has extensively visited colleagues abroad: at the University of Adelaide, Bellcore, Central South University, the University of Delaware, the University of Melbourne, the University of Pisa, and the Tokyo Institute of Technology.

His research activity includes various aspects of computational probability: he has participated in the development of matrix-analytic methods for the analysis of Markov models, with applications in queueing theory, telecommunication systems, fluid queues, branching processes and ruin theory. He has also shown a minor, but recurrent, interest for nearly completely decomposable systems.

He has co-authored three books, edited ten monographs, and has more than 100 scientific papers published in the refereed literature; he has successfully supervised 10 PhD students and been co-chair of the programme committee for several international conferences of high standing.

Keynote Speech 1: A network model for financial systemic risk

Speaker: David D. Yao, Columbia University, New York, USA.

Abstract: We study default and contagion dynamics in a financial system modeled as a high dimensional dynamic complementarity problem, also known as Skorohod problem. An algorithm that solves the Skorohod problem will generate all possible default times over any given horizon, along with the evolution dynamics of each bank's asset values, liabilities and payment flows. The results inform the development of new risk measures for default clustering and contagion concentration.

It is known that the contagion effect during a financial crisis materializes through two mutually enhancing channels of interconnectedness. The first one is the direct connection among the banks via their respective on- and off-balance-sheets activities. The second channel for contagion arises from the banks' interconnectedness indirectly through the market. Fire sales at a distressed bank to raise cash to meet debt obligations will create a serious negative externality for the rest of the system. The last financial crisis (of 2007-09) shows that the two channels of contagion may form a vicious circle to reinforce each other leading to systemic catastrophe. Our dynamic network model clearly brings out the prominence of the market effect, which makes the financial network qualitatively different from say, social networks --- the market can spread contagion much faster and wider than the diffusion through neighboring nodes that is typical in social networks.

Keynote Speech 2: Trilogy on computing maximal eigenpair

Speaker: Mu-Fa Chen, Beijing Normal University, China

Abstract: The eigenpair here means the twins of eigenvalue and corresponding eigenvector. The talk introduces the three steps of our study on computing the maximal eigenpair. In the first two steps, we construct efficient initials for a known but dangerous algorithm, first for tridiagonal matrices and then for the irreducible matrices, having nonnegative off-diagonal elements. In the third step, we present two global algorithms which are still efficient and work well for a quite large class of matrices, even complex for instance.

Keynote Speech 3: A matrix-analytic approach to Markov-modulated Brownian motion

Speaker: Guy Latouche, Université Libre de Bruxelles, Belgium

Abstract: Ramaswami has shown in 2013 that standard Brownian motion is the limit of a family of two-phase fluid queues with increasing rates of transition from one phase to the other. This has motivated us to investigate Markov-modulated Brownian motions (MMBMs) from a matrix-analytic point of view, starting from a Markov-regenerative approach and using fast-switching fluid queues as a tool to determine the required characteristics.

Fluid queues, are a particular family of MMBMs characterized by the fact that the evolution is piecewise linear without Brownian noise. A key consequence is that stochastic fluid queues are amenable to Kolmogorov-type analysis. We present here a summary of the idea behind the technique and of the results obtained so far.

Keynote Speech 4: A two-threshold optimal sleeping policy for a single server queue with bursty traffic

Speaker: Zhisheng Niu, Tsinghua University, Beijing, China

Abstract: Making idle servers sleep is considered to be a key approach to reduce energy consumption of various information and communication systems. Optimal sleeping policies for a single server have been derived only for non-bursty traffic in prior work. In this talk, for the first time, we study the optimal sleeping policy for a single server queue with bursty traffic. Key factors including switch-over energy consumption as well as delay performance are considered. We formulate the problem as a POMDP (partially observable Markov decision process), and show that it can be solved by observing the time elapsed since the last arrival (TESLA). The optimal sleeping policy is shown to be a wait-and-see two-threshold policy and the simulation results show the effectiveness of the policy. Numerical results also show that traffic burstiness can help to enhance the system performance in terms of weighted sum of the energy-efficiency and delay.
