We consider three M/D/1 models with retrial calls in terms of aircraft landing. In model I, which has been analyzed by L. Lakatos, dwell time on the orbit is constant, a discipline service is first in, first out. In model II, which has been investigated by E.V. Koba, an assumption about the cited discipline is violated. In model III these assumptions are extended only to delayed aircraft. And what is more, dwell time on the orbit can not be less than the constant value T.

It is shown, that Bayesian approach is the basis of constructing inductive inference procedures. Issues of application of this approach in inductive logic, Bayesian networks and information theory are discussed.

We consider the problem of determination of quantitative indexes of competence of group members relative to a problem, which is under decision making. The coefficient of similarity of keywords of the subject under discussion with basic keywords is introduced and a method for determination of this coefficient is suggested. The method for calculation of estimate of competence of a group member with respect to a basic keyword is grounded on integration of self-estimate, mutual estimate and estimate on the basis of documental data. We suggest also methods for determination of these components for competence estimate.

We propose a variety of approaches to solving the classes of search problems by example a series of the problems of signals search in a multichannel system by a single searching device. The mathematical apparatus of the theory of Markovian and semi-Markovian random processes is used.

We present results of investigation of the averaged equations for optimal with respect to velocity orbit-to-orbit transfers, which were obtained by authors before. We obtain analytical solutions in elementary functions of the problem for maneuvers of changing shape and size of the elliptic orbit with simultaneous alteration of one of the angles, which define its location in space.
Describing of a Case of Purposeful Behavior of Living System in Which There Is No Contradiction Between Purposefulness and Physical Causality (or Cybernetics Does Live, Yes, It Lives!)

Institute of Psychology of Academy of Psychological Sciences of Ukraine, Lugansk, Ukraine
This article is a response to the opened in the Journal discussion about "rational theoretical basis for existence of cybernetics". A mental experiment is described, in which a living system "demonstrates" behavior characterized by absence of contradiction between "determinism by goal" and physical determinism. It is shown, that a correct analysis of such a case and its consequences becomes possible only if it includes some assertions of semiotics and if this analysis highlights in the goal-orienting process another process of signifying with at least two sides, semantic and syntactic.
