Abstract
The goal of this paper is to compare quality assurance in different
contractor contracts by means of multi-attribute decision-making
(MADM) and to select the best option. For this investigation, the
authors have developed the complex of quality evaluation criteria.
During experimental evaluation, the significance of criteria was
determined and the expert evaluation of template construction
contracts was performed. The complex comparison of contractor
contracts was carried out by means of the following MADM methods:
Simple Additive Weighting (SAW), Technique for Order of Preference
by Similarity to Ideal Solution (TOPSIS), Complex Proportional
Assessment (COPRAS) as well as the new Evaluation Based on Distance
from Average Solution (EDAS). MADM. method. To determine the
weights of criteria, with due consideration of uncertainty of expert
evaluation, the Fuzzy Analytic Hierarchy Process (FAHP) method was
applied. Evaluation of the data structure was performed by methods
for the determination of objective weights: an entropy method and
new criteria impact loss (CILOS) and integrated determination of
objective criteria weights (IDOCRIW) methods. Expert subjective and
objective weights were combined into aggregate weights. Based on
the investigation performed, the authors make conclusions regarding
possibilities for improving quality assurance in contractor contracts.
