This paper proposes the way to slove the optimization problem of random variable cross- sectional beams and different boundary conditions by strength and stiffness critris. The optomization problem is solved by lagrange multiplier method. The procedure of calculation of optomization process is established and implemented by MathCad calculation programming software.
