Abstract

The software package SAPOP (Structural Analysis Program and Optimization Procedure) has been developed as an optimization procedure on the basis of various calculation methods of structural mechanics applying algorithms of the mathematical programming and the important “optimization modelling”. Besides the actual formulation of the optimization problems, the optimization model consists of the so-called “strategies”. Presuming several criteria or objective functions, various techniques of vector or multicriteria optimization will be used as a strategy. Further strategies were established and implemented for shape optimization problems and multilevel optimization techniques (decomposition strategy). The practical application and some results of the efficiency of the developed optimization procedure are shown by two examples from space research, among others the design of highly accurate radio telescopes and the shape optimization of a satellite tank.
