Daugiakriterinio vertinimo rodiklių svorių nustatymas, remiantis jų tarpusavio sąveika

When the number of the criteria used in determining the criteria weights in multicriteria evaluation is sufficiently large some problems can arise. Problem solution may be simplified by assuming that the criteria describing various aspects of the object are interrelated as the elements of the system. These relationships form the potential of each element of the system which can increase or decrease, depending on the relationships between the elements and their nature. To determine the directionality and strength of interrelationship between the system elements, it is sufficient to have an expert's judgement about the directionality and strength of the relationship between one element and all other elements of the system. Then, basing themselves on the transitivity of interrelationship between values, we can determine the directionality and strength of relationships of the remaining elements. Given the calculated and actual potential of each element of the system, the weights of the elements can be determined
