Multi-Criteria Optimization Software LEVI-4.0 a Tool to Support Design and Management in Construction

Multi-criteria decision making is used in many areas of human activities. Criteria can to be qualitative and quantitative. They usually have different units of measurement and different optimization direction. The normalization aims at obtaining comparable scales of criteria values. In the new program LEVI 4.0 version the following normalization methods are possible: vector, linear scale, non-linear and new logarithmic techniques. This software considers the main positions of two-sided game problems. The strategic principles are used as follows: Wald's rule, Savage criterion, Hurwicz's rule, Laplace's rule, Bayes's rule, Hodges-Lehmann rule. This program is demonstrated with a real case study involving 4 evaluation criteria of external walls of the individual residential buildings, now in use.
