Selected Aspects of Multi-Criteria Analyses Supporting Assessment of Construction and Material Solutions in Buildings and Building Structures

Abstract

Decisions concerning planned buildings and building structures are made as early as the stage of planning development investments. Different variants of construction solutions and materials are evaluated, which entails reviewing numerous physical, chemical or maintenance factors. The more factors are involved, the more difficult it is to make a decision. While analysing alternative solutions, the decision-making process can be supported with a variety of methods. A possible approach is to employ a multi-criteria decision analysis method. Such methods will differ from one another in the way data are processed for analyses, in the methodology of analyses and in the form of an output. Moreover, every method may be burdened with errors. This article presents various problems connected with an analysis of data accomplished according to the MCE, AHP and Indicator Method, and arising during the interpretation of results.
