Title:    Decision Making under Uncertainty - Stochastic Programming and Modeling

Lecturer:    Prof. Stein Wallace (Norway, currently visiting the Chinese University of Hong Kong)

Time:    2008年4月18日（星期五），2: 00 - 4: 05pm

Place:    4教4304

Format:    2 lectures, 1 hour each with 5 minutes break in between

### About the two lectures ###

Lecture 1 - Why sensitivity analysis does not work? (1 hour).

The purpose of this talk is to set the scene for why a stochastic program, complicated as it is in terms of formulation, data collection and solution time, might in fact be needed. In particular, we show why such as sensitivity analysis and what-if analysis will not suffice.

Lecture 2: Modeling in stochastic programming: Stage structures. (1 hour)  
The purpose of this talk is to characterize stochastic programs in terms of inherent stage structure, and indicate how one might model the information part of the problem dependent on the inherent stage structure. Examples are given.

### Brief C.V. of Prof. Stein Wallace ###

Stein W. Wallace is professor of quantitative logistics at Molde University College, Norway. He holds a dr.scient in informatics from the University of Bergen (1984). His main interest is on decision-making under uncertainty, with an emphasis on Sochastic programming. He has published three books (among them the world's first textbook in stochastic programming) and more than 50 articles in scientific journals. He is associate editor of INFORMS J. on Computing, Optimization and Engineering and the stochastic programming e-print series. He has chaired the Committee on Stochastic Programming, and held elected and appointed positions in INFORMS and The Mathematical Programming Society.  He has held visiting positions in the USA, Sweden, Switzerland, France, Iceland and presently Hong Kong.
