In this paper, firstly, an improved penalty function method for solving the optimal design of nonlinear discrete variables is given. In the method, the initial value of the penalty coefficient is selected by the general optimization method. In order to avoid the ineffective circulation, the relevant treatment measures are given in the article. Secondly, according to the characteristics of the driving derrick structure, this paper gives the concrete steps of the discrete variable optimization design and the matters needing attention in the calculation. At the end of this paper, an example is given and compared with other substituting results to show the superiority of this method.
