    Work Roll Cooling System Design Optimisation in Presence of Uncertainty
    (Cranfield University Press, 2009-03-31) Azene, Y. T.; Roy, Rajkumar; Farrugia, Didier; Onisa, C.; Mehnen, Jorn; Trautmann, H.; Rajkumar Roy; Essam Shehab
    The paper presents a framework to optimise the design of work roll based on the cooling performance. The framework develops Meta models from a set of Finite Element Analysis (FEA) of the roll cooling. A design of experiment technique is used to identify the FEA runs. The research also identifies sources of uncertainties in the design process. A robust evolutionary multi-objective algorithm is applied to the design optimisation I order to identify a set of good solutions in the presence of uncertainties both in the decision and objective spaces.
