Paretooptimal solutions of the inverse problem of gravimetry with indeterminate a priori information
© T.N. KishmanLavanova, 2015
The paper discusses theoretical aspects of solving the nonlinear inverse problem of gravimetry with uncertainty of a priori
information. The a priori information is described by fuzzy sets. Specialpurpose geophysical problem with uncertain a priori information
is transformed into a multiobjective optimization problem. One of the criteria is the membership function of a fuzzy set of possible solutions.
Solution of the problem is a set of Paretooptimal solutions, which is constructed in the parametric space applying a threestep search
algorithm. The advantage of the proposed method is that it provides a possibility of including the wide range of non probabilistic
a priori information in the inversion procedure and can be applied to the solution of highly nonlinear problems. This reduces the number
of direct computing problems by selective modeling of sample points in the parametric space. A test example has been given of the
algorithm applied to the inverse problem of gravimetry for a single contact surface.
Key words: inverse problem of gravimetry, indeterminate a priori information, Paretooptimal solution.
