The purpose of this article is to develop and improve systemic methods for constructing solutions to engineering problems. The article provides a methodological approach to solving complex engineering problems based on the application of the system analysis method. The need for a preliminary assessment of the completeness of the initial data for the construction of a mathematical model of the problem is shown.
At the stage of the problem statement, the problem statement is concretized in order to establish the research goal. As a result of a systematic analysis of the functional characteristics of the object under study, the main parameters and their relationship are determined, and the values of these parameters characterizing the initial state of the object under study are established. It is necessary to clarify the essence of the problem and formulate it so that the solution found is effective and can be obtained using existing means and in real terms. Based on the data of the analysis, the goal of solving the engineering problem is determined and the corresponding formulation is formulated in the following form: initial data; parameters; quantities to be determined.
The functional connections between the main parameters of the object and the factors acting on it are established, they are described by mathematical relations and equations included in the mathematical model, taking into account the determining influence of the parameters of the problem on the state of the object. Thus, we obtain a mathematical formulation of the problem, the construction of the solution of which allows us to establish the parametric dependence of the state of the object for various values of the parameters. The reliability of the results obtained and the suitability of the chosen method, the decision should be confirmed by their testing and careful analysis.
On the basis of the formulated approach, assessments have been carried out and the corresponding technological operations have been proposed for solving the engineering problem of removing the tanker «Delfi» from the aground in the water area of the Odessa coast of the Black Sea. The expediency of further improvement of the technology of application of the proposed approach for design tasks and industrial development of software and hardware complexes has been determined.
