New model for the selection of effective wall solutions for residential buildings

Currently, the construction sector is facing requirements for higher quality and efficiency standards as well as objectives related to value creation. In construction, rational decision-making problems often involve creating a unique complex of criteria, which must consider multiple requirements and conditions. The paper presents the developed model for the selection of multi-layered external walls of a residential building. The model considers the following aspects and parameters: time, cost, quality, environmental conditions, aspects of sustainable development, and problemsolving benefits received from the assessment of alternatives and the development of the model. Game theory was used to calculate the defining rational decision. For the calculations was used game theory: Bayes, Wald’s rule, Savage criterion, Laplace’s rule. This study presents the developed model for the selection of multi-layered external walls of a residential building and calculation results based on game-theory rules, which are effective tools for rational decisionmaking.
