The traditional structure optimization modeling methods require higher capability to designers,the existing auxiliary optimization modeling tools lack of flexibility,and hence it is very difficult to build an engineering optimization model for complex problems. Therefore, a strongly universal auxiliary optimization modeling method is proposed. The idea of the Design Structure Matrix( DSM) is introduced into the building process of optimization modeling. The advantages of DSM structure form and algorithms are utilized,and the optimization model and rational optimization process can be easily and effectively extracted from complex engineering problems. An auxiliary optimization modeling tool is developed by the Excel VBA language,which can automatically map the optimization modules to an optimization flow chart by the interface program of the optimization software Isight. The optimization design problem of a gas turbine support structure is used to verify the auxiliary optimization modeling tool,which shows good effect.
