The methods of multi-attribute analysis were tested in many fields and applied to different disciplines as well as to solving many specific problems. In spite of these facts, multi-attribute analysis is not sufficiently developed, the methods are not perfect, and scientists constantly raise the question, “Which is the best method for a given problem?” Most of the methods enable us to determine the priority rank for comparing the alternatives, not allowing, however, to establish the level at which one alternative can be better than another. The members of EWG-ORSDCE have created a series of new optimization methods, which were successfully applied in different fields:

The successful cooperation between the stakeholders during the construction life cycle results a smooth flow of construction processes. However, the fact that construction environment is usually uncertain, unstable and therefore unpredictable should be taken into account. Technical solutions and managerial decisions made in such environment should be substantiated by proper methods, which let to process not complete and expressed in certain ranges (intervals) data. The correct methodological approach let to avoid unwanted disputes and other undesirable obstacles that impede the construction process and led to delays. To process the uncertain data expressed in intervals the members of EWG-ORSDCE introduced the modifications of earlier created methods:

For rational dispute resolution Keršulienė, V., Zavadskas, E. K. and Turskis, Z. in 2010 offered the Step-wise weight assessment ratio analysis (SWARA) method. In 2008 a new logarithmic normalization method was presented. In 2006 FARE (Factor Relationship) method, allowing to determine the weights of a large number of criteria based on the relationship between one of them and the others was presented by Ginevičius R.

Uncertainty and imprecision involving multiple criteria, the intersection of goals and constraints could result the necessity to use the fuzzy logic in decision making. Fuzzy logic is an extension of the traditional logic to intermediate and approximate values that capture the meaning of words, human reasoning, and decision making. For multi-attribute selection of an alternative under uncertainty conditions E.K.Zavadskas, L.Ustinovičius, Z.Turskis, F.Peldschus and D.Messing created and in 2002 announced the software LEVI–3.0 based on different methods for attributes normalization and optimal variant selection. The application of these methods increases the accuracy of determining an optimal decision. With new software it is possible to find solution of rational strategy problem using different methods under risk and uncertainty and to compare the results. To process the fuzzy data the members of EWG-ORSDCE introduced the methods:

By applying the methods of multi-attribute analysis to different cases the authors of research papers noticed the regularities and pointed the statements that should be considered in further applications. For example, for the reason to make the efficient decision it is purposeful to use not large number of attributes including their weights. Considering the large number of attributes and ignoring their weights the less important attributes have high influence on final result. Therefore, the risk exists that irrational decision could be selected. Moreover, when the variants are characterized by large number of attributes rated in 10 points scale with the accuracy of calculation is 0,5 point, or 5% the attributes with significance less than 5% have less influence of final result than the values of possible errors and could be eliminated from decision-making matrix
