Resumen
The article is devoted the problem of optimization of parameters of constructions with geometric inhomogeneities, which are in the aggressive environment. For its solution the algorithm of directed search was built based on the stage principle and including the known methods, which are successfully combined to solve the intricate problems of the optimum planning of transport constructions under the aggressive environments action. As an illustration the example of optimum search of circular opening reinforcement in a plate under corrosive wear is considered.
