A New Synthesis Method of Structural, Technological and Safety Decisions (Symad-3) / Naujas Konstrukcinių, Technologinių Ir Saugos Sprendimų Sintezės Metodas (Symad-3)

Abstract

Abstract. The paper provides a new synthesis method of multiple attribute decisions (SyMAD-3 -Synthesis of Multiple Attribute Decisions using three methods) intended for combining multi-stage and multiple attribute decisions into a single common estimate. The method is applied for selecting a construction project on the basis of its structural, technological and safety decisions. To increase the reliability of the decision, three multiple attribute decision-making methods based on quantitative measurements were applied to help the person making a decision to monitor the results of a relevant decision obtained employing three methods of the same class. The algorithm of the proposed method includes methods for identifying the integrated significances of attributes and multiple attribute decision-making methods (SAW -Simple Additive Weighting, TOPSIS -Technique for Order Preference by Similarity to Ideal Solution, and COPRAS -COmplex PRoportional ASsessment) based on quantitative measurements.

Information Technology Applications in Construction Safety Assurance

“…10. Worker's visibility at different locations (A, B, and C) close to equipment (Teizer et al 2010) A synthesis method for multiple-attribute decisions has been proposed to increase the correctness of the rendered decisions by assessing alternative construction, technological and occupational safety solutions in uncertain jobsite conditions (Simanaviciene et al 2012(Simanaviciene et al , 2014. Also, a multi-stage decision model reflecting a set of available combinations of alternatives has been developed to evaluate the effect of each criterion and its interaction with other criteria, which in turn assists with choosing appropriate solutions for structural design, construction technology and work safety challenges at hand (Liaudanskiene et al 2012).…”

Selecting a Location for a Liquefied Natural Gas Terminal in the Eastern Baltic Sea

“…SAW is the oldest, most widely known and practically used method. The idea of qualitative multi-criteria methods is well demonstrated by the SAW method (Hwang, Yoon 1981;Palevičius et al 2013;Simanavičienė et al 2012;Yazdani-Chamzini et al 2013;Chen 2012).…”

An Integrated Multi-Objective Optimization Model for Solving the Construction Time-Cost Trade-Off Problem

“…Fourth, aside from TCTP, several studies have considered the quality, environment, and productivity at the same time (Hsieh, Liu 2004;Balling et al 2004;Huang et al 2009;Jiang et al 2011;Liu et al 2012;Simanaviciene et al 2012). El-Rayes and Kandil (2005) tried to solve the time-cost-quality trade-off problem in highway construction.…”
