Background of the task of the choice of combinedexperimental design in modeling the process of resourcesproducts
We solve the problem of choosing the most effective for optimizing the combined plans of the experiment the objective function in the modeling of resources. At the same time take into account theoptimi-zation criteria, which characterize a specific plan of the experiment. The object of investigation was the turbine unit for which the assessment of damage to elements of nodes under the conditions of operation and bench test requires knowledge of theirloading in different modes of operation.
