Research Areas

Flexible Operations Strategy
(De Meyer, Holweg, Scholtes)

This area focuses on a firm's ability to manage diverse demand and supply and respond to unfolding uncertainties or unforeseen circumstances. Holweg's award-winning work on the implementation of responsive manufacturing strategies in the global motor industry involved research at vehicle manufacturer and supplier plants in Europe, USA, South America, Korea, Japan, China and Australia. De Meyer's work focuses on the management of projects under uncertainty, based on case studies combined with mathematical modelling. Scholtes researches on flexible engineering design in collaboration with MIT and on the economics of collaborative innovation with practical applications, e.g., through his involvement in structuring a flexible, industry award-winning co-development alliance between Cambridge Antibody Technology and AstraZeneca.

Theory and Applications of Mathematical Modelling
(Jiang, Ralph, Scholtes)

Ralph and Scholtes continue their analytical work and algorithm development for mathematical programmes with equilibrium constraints (MPEC). A recent major breakthrough was the establishment of the conditions for convergence of a standard optimisation algorithm when applied to MPEC models. Jiang has recently proposed the first efficient column generation method for the uncapacitated task allocation problem, which sets a benchmark in the field in terms of solution quality and time. Steinberg's leading role in editing Combinatorial Auctions (MIT Press 2006) has established him as a key figure in this growing field.
