The following problems are solved: the substantiation of the method of choosing the optimal place for the forced landing of an aircraft on the water surface, developing a method of the optimal route calculating for carrying out the evacuation operations, estimating the factors influencing the forced landing, evacuation and the process of further survival. Methods. In order to assess the degree of the factors of influenced, the method of expert evaluations is used. The task of optimizing the evacuation route is solved using the methods of the graph theory. Results. The article outlines the results of an expert survey aimed at identifying the factors that have the greatest impact on the process of ditching and further survival rate. The isolated complex factors (Landing Conditions, Evacuation Time and Eligibility of the Settlement, for Victims Assistance) are explored. The factors like Landing Conditions and Eligibility of the Settlement, for Victims Assistance are estimated by the experts, their impact is expressed in terms of weight, reflecting their danger. The task of reducing the time of evacuation is solved by applying the methods of graph theory. Conclusions. The research describes and justifies the method of selecting the optimal place of ditch. This method can be used by flight crews during the situations on board, which prompts to perform the forced landings.

For successful management of the banks’ deposit activity it is important to understand how to change the deposit attraction programme if the time structure of deposits has suddenly changed. The existing studies are mainly devoted to the analytical calculations of attracting programmes under conditions when the time structure of deposits is described by the continuous functions. There are scientific researches in which a methodology for calculating the deposit attraction programme are developed, provided that the time structure of deposits is discrete, which made it more similar to the problems that arise in each bank practice. However, in reality, the deposits attraction are outraged by random processes. Purpose. Therefore, the bank faces the task of assessing or forecasting a programme for attracting deposits under conditions of incomplete information (stochasticity). Methods. The task of evaluating the programme for attracting deposits under conditions of Gaussian noise is solved with the Kalman filtering procedure. Since the equation describing the discrete changes in the deposit attraction programme is a Voltaire difference equation of the convolution type, the Z-transformation is used to bring it to the standard representation in the state space. The scheme of the non-stationary Kalman filter is implemented in the form of a "predictor-corrector". Results. The algorithm for evaluating the programme for deposits attraction in the case of a random Gaussian process is developed. The equations for the non-steady-state Kalman filter are obtained. The numerical results clearly demonstrate the stable operation of the implemented filtering algorithm. Conclusion. The developed algorithm for estimating a discrete programme for attracting deposits in the presence of a random Gaussian process is useful for software developers at the banking institutions. Its usage helps to improve the decision-making system for banks’ deposit management. For future research, it is necessary to consider the random distortions described by Gaussian color or shot noise, when there are the rare but significant outliers of the balances on the bank’s correspondent account.
