A Robust-Solution Based Methodology to MO Problems

Robustness is a very important concept present in diverse areas related to MCDM. In general words we can say that robustness is an attribute related to the “ability of a subject to cope well with uncertainties” [8], more precisely the uncertainties that accompany the input of a system. In this work we are particularly interested in the concept of robust solution in optimisation and its application to find the final set of alternatives in Multiple-Objective problems (MOP). The application of robustness described here is framed in a specific “Released when Completing blocking” (RCb) bi-objective hybrid flowshop scheduling problem, but the methodologies studied can be adapted to other classes of problems.
