Structural synthesis using the MINLP optimization approachKravanja, StojanThis paper presents a structural synthesis using the Mixed-Integer Non-LinearProgramming (MINLP) approach. The MINLP is a combined discrete/continuous optimization technique, where discrete binary ... 0-1 variables are defined for optimization of discrete alternatives and continuous variables for optimization of parameters. The MINLP optimization to a structural synthesis is performed through three steps: i.e. the generation of a mechanical superstructure, the modelling of an MINLP model formulation and the solution of the defined MINLP problem. As the discrete/continuous optimization problems are usually non-convex and highly non-linear, the Modified Outer-Approximation/Equality- Relaxation (OA/ER) algorithm is selected to be used for the optimization. The accompanied Linked Multilevel Hierarchical Strategy (LMHS) is developed to accelerate the convergence of the above-mentioned algorithm. Some examples are presented at the end of the paper.Source: Computer aided optimum design in engineering IX (Str. 75-84)Type of material - conference contributionPublish date - 2005Language - englishCOBISS.SI-ID - 9628694
