Professor Stein W. Wallace

Formerly at Lancaster University

Current Teaching

MSCI 535 Optimization (MRes - part of STOR-i)

MSCI 574 Logistics (which includes MSCI 544) (MSc in logistics and Supply Chain)

Current Research

I am particularly focussed on how uncertainty affects optimal solutions in stochastic integer programs. Just now I am working on stochastic network design and facility layout.

I am also starting to look into energy problems, partly by creating contacts with UK companies and organizations, partly by re-establishing Norwegian ties.

Research Interests

Decision-making under uncertainty

  • Stochastic programming
  • Stochastic network design
  • The art of modelling
  • Multi-item newsvendor models with dependencies
  • Energy modelling


  • PhD in Informatics, 1984. University of Bergen, Norway
  • MSc in Mathematics, 1981, University of Bergen
  • BSc in Mathematics, Informatics, and Economics, 1979, University of Bergen

Professional Role

I am strongly involved in STOR-i, our EPSRC funded Doctoral Training Centre, and The LANCS Initiative, a major EPSRC programme to strengthen OR in the UK.

Research Grants

Grant from the Grant Council of Hong Kong on the importance of uncertainty in air-freight forwarding. (With L. Leung of The Chinese University of Hong Kong and YV Hui of The City University of Hong Kong.) 2011-12.
