This paper considers the main positions of one‐sided and two‐sided problems. For one‐sided problems only the method of solution “the distance to the ideal point” is discussed in the actual version. For two‐sided problems a distinction is made between games with rational behaviour and games against nature. The main strategic principles are as follows: simple min‐max principle, extended min‐max principle, Wald's rule, Savage criterion, Hurwicz's rule, Laplace's rule, Bayes's rule, Hodges‐Lehmann rule. Questions of transforming the decision‐making matrix are considered. The article gives the description of a software as well as an example of an investment variant estimation.

The new method for the construction of partial order on the set of multicriteria alternatives is presented. This method belongs to the family of Verbal Decision Analysis methods and gives a more efficient means of problem solution. The method is based on psychologically valid operations for information elicitation from a decision maker: comparisons of two distances between the evaluations on the ordinal scales of two criteria. The information received from a decision maker is used for the construction of a binary relation between a pair of alternatives which yields preference, indifference and incomparability relations. The notion of a method decisive power is introduced. The illustrative example is given.
