The problem of discrete analysis of logistic information situation is studied. A method of clear interval functions for situation analysis is proposed. The content of the situational task is revealed. The method is an alternative to fuzzy interval situations. Interval functions are described. In fact, the solution of a discrete optimization problem is given. The difference between physical and parametric interval situations is shown. The aim of the work is to develop a new discrete optimization method. A new concept of interval situation is introduced. The solution of the problem is given in three variants for three optimization criteria. The method is heuristic and is shown with an example. The necessity of replacing the term «global optimality» with the term «local optimality» or «expedient solution» is shown. The method allows you to solve a situational problem for any number of criteria including criteria.
Key words: situational problem, interval function, logistics, logistic situation, discrete optimization, expedient solution, local optimization, heuristics.
