Abstract: | The mathematical modelling for optimization is a highly iterative process that implies a series of steps regarding the identification of the parameters and variables which characterize the analysed phenomenon, the definition of the evolution sets of the indices of these elements, the specification of the definition field of the variables, the elaboration of the objective function, writing the algebraical or differential relations which link the variables and the parameters and gathering data associated to the model. The design of a resistance structure supposes, on the basis of the stresses and strains produced by the actions it is subjected to during exploitation, to select the material needed for the execution, to establish the geometric form and to dimension the structural elements on the basis of the criteria of safety and reliability in exploitation, observing at the same time the criterion of economic efficiency. |
