In this study space truss systems were design optimized by using fuzzy sets. For this aim l formulation was applied. The analysis of the truss system is made with respect to matrix-displacement method. The algorithm of multi-objective fuzzy optimization was formed using the macros of Ms-Excel. A number of design examples are presented to demonstrate the(More)
