Abstract: In construction, the selection of effective construction alternatives is based on decision according to technological and economical analysis. The choice and analysis must be made independent of any preferences or interests and must be supported by a precise calculation of significant criteria such as economic benefit, workability of alternatives and investments. The comparison of normalised dimensionless criteria values, using particular optimal solution methods, is one of the basic stages in evaluation process. Therefore, normalisation method must be chosen according to the objectives so as to meet special requirements, with regard to possible inaccuracy or uncertainty threats and influence on the final ranking of the alternatives or even the final decision.

Keywords: normalisation methods; uncertainty influence; multicriteria decision making; MCDM; decision support systems; DSS; game theory; construction alternatives; dimensionless criteria; construction industry.
