Approximate goal programming model for optimization design of submarine pressure hull structure

According to the tactical technical specification,it is the chasing first goal to the mast of the op - timal scantling and optimal mechanical property of the structure material in the optimization design of submarine pressure hull structure.Using approximate goal programming the multiple goal model can be turned into single-goal programming model under nonlinear constrained optimization.Solving the optimum solution corresponding to the continuous variables and the discrete variables,and rounding these variables to normalized variables,and at last the relative effective solution is obtained which is corresponded to full the stresses design and relative lighter the pressure hull weight.
