The paper deals with discussion of discrete optimization problem in structural space-truss design. The cross-sectional areas of truss bars are taken as design variables. A catalogue of circular hollow sections for truss bars and a numbers of the series of types of cross-sections of bars are taken as discrete decision variables. The stress, local stability, displacement (design) constraints as well as technological and computational constraints are taken into account. The mass of truss bars including mass of joints as well as exploitation and maintenance costs are chosen as optimization criteria. A numbers of the series of types of cross-sections of bars t is also taken as a criterion of optimization. The sets of non-dominated (efficient) and compromise (Pareto optimal) solutions and the preferable solution for space truss are found. The results are presented in the form of diagrams.
