We present about an examination on the design method to optimize some kind variables. It is considered that microstructural design of composite material by using beam model. In the case that additional reinforcements are inserted to a base structure, topology, location or cross-sectional shape of reinforcements will be considered as design variables. In order to construct a design system for simultaneous design of both layout and cross-sectional size, differences of each solution which can be obtained by different design procedures for the multiple types of design variables are investigated. In this time, a cantilever with a slit at the center is optimized by using the steepest descent method as one of the simplest example. The results show a difficulty of the design and a necessity of the design method which can search the optimum solution stably with lower computational cost.
