This article deals with the new approach of finding defuzzification / ranking index various types fuzzy sets. Traditionally, in most articles on decision making methods are not justified respect to that highest aspiration levels. study highlights an efficient (ranking) method which links between gaps defuzzified values obtained using ?-cuts and without numbers. Moreover, for a given problem dif...

The article has considered the method of vessels possible collision area constructing in problem guaranteed avoidance controlled vessel with unpredictable target-vessels. Reachable set is expanded defined safe distance, segments enlarged combine and form area, which convenient for practical use. Performed researches contribute to improvement ship’s handling methods.

We address the problem of identifying a useful set of mutually compatible separation axioms for each category T-FNS of T-neighbourhood spaces. It should contain one of T-complete regularity that characterizes T-uniformizability, as indeed we achieve here. This seems to necessitate the parameterization of most separation axioms by the triangular norm T, with the exception of the two axioms T0 an...
