Multiple criteria assessment of pile-columns alternatives

Abstract

The paper presents the process of selection the pile-columns instalment alternative, which have to be the most appropriate and effective. The selection is based on a set of criteria: Mass, Cost of instalment, Labour expenditures, Machinery expenditures, Earthwork amount and Instalment tolerance. The criteria for evaluation are selected by taking into consideration the interests and goals of the client as well as factors that influence the efficiency of construction process. Their weights were determined by applying entropy method. The entropy is described as the casual value of the uncertainty which makes it more valuable in comparison wiThother factors. The solution of problem was made by applying Additive Ratio ASsessment (ARAS) method. The proposed technique could further be applied to substantiate the selection of effective alternative of structures, technologies, investments, etc.
