Evaluation of Planned Construction Projects Using Fuzzy Logic

The study presents a model for the evaluation of construction projects from the point of view of the client (e.g. developer company). the problem lies in choosing the best solution from the point of view of many criteria. the proposed model is based on a multi-criteria comparative analysis using fuzzy logic. the first part of the paper presents a selection of criteria describing the construction project along with their description. the set of attributes describing the analysed object was determined on the basis of the synthesis of specific proposals for the parameters of construction projects. the set of criteria has been divided into two groups: technical,technological and organisational criteria and separately the economic criteria. then,the number of variables describing the observations was checked using principal component analysis (pca). course of action was presented in the event of multiple criteria analysis using the fuzzy set theory. both the weights and the evaluations of individual criteria were modelled using membership functions due to the fact that when describing a construction project,or the validity of the criteria of describing variables,they are approximate. an analysis of the correlation of selected project criteria was presented. the proposed decision support model of assessing a construction project makes possible to compare various variants based on 11 factors identified. the use of fuzzy logic has enabled more accurate description of the phenomenon analysed when the exact parameters of the project in the planning and preparation stage of the project are not known. © 2017,the author(s).
