Abstract
Structural design problems, which usually involve multiple conflicting criteria to
be considered simultaneously, often occur. In this paper, three objective
functions are considered, i.e. weight, displacements and von Mises criterion, in
application to sizing optimization of bending (beam) and 2-D (plane stress state)
structures. Design variables are represented by thickness parameters, and the
constraints deal directly with displacements and/or stresses. Then various
multicriteria problems are formulated. A scalarization method based on the game
theory is applied. Linear programming techniques are employed to find the
weighting coefficient
