Now –adays the multi-criteria decision making methods are gaining importance for selection of best suited alternative among the available alternatives. Decision makers in the construction industry frequently face the problem of assessing a wide range of alternative options, and selecting one based on a set of conflicting criteria. MCDM methods are based on aggregating function representing “ cl...

Promethee II is a prominent method for multicriteria decision aid (MCDA) that builds a complete ranking on a set of potential actions by assigning each of them a so-called net flow score. However, to calculate these scores, each pair of actions has to be compared, causing the computational load to increase quadratically with the number of actions, eventually leading to prohibitive execution tim...

Green House Gas (GHG) emissions from corporate activities are gradually becoming a mainstream management issue for businesses. The GHG Protocol Scope 3 Corporate Standard has been adopted as the international standard to report a corporation’s overall emission profile of their value chain activities. Through Scope 3 Corporate Standard, companies can recognize potential emissions and associated ...

Supplier selection is an important issue in supply chain management (SCM), and essentially is a multi-criteria decision-making problem. Supplier selection highly depends on experts’ assessments. In the process of that, it inevitably involves various types of uncertainty such as imprecision, fuzziness and incompleteness due to the inability of human being’s subjective judgment. However, the exis...

Based on the characteristics of supplier selection for CALS(Continuous Acquisition and Life-cycle Support), that companies with CALS have many suppliers and suppliers are always strategic suppliers, supplier selection process is divided into two phases: pre-selection and making decision. At supplier pre-selection stage, polychromatic sets theory from Russia is introduced as the solution scheme....

Selecting a process for welding large scale equipment on site demands special expertise due to the numerous variables be considered. This paper is aims applying decision support methodology selection of 16000 cubic meter storage tank welded site. Five processes are chosen select from, namely, Gas Metal Arc Welding (GMAW), Shielded (SMAW), Submerged (SAW), Flux Cord (FCAW) and Tungsten (GTAW). T...

The paper deals with the valued comparison of intervals for decision making. Interval orders are classical preference structures where the comparison of intervals is done in an ordinal way. In this paper we focus on valued comparison where more information, especially the distance between end-points of intervals, is used in order to have more sophisticated preference relations. The generalizati...

We introduce a new multiple criteria ranking/choice method that applies Dominance-based Rough Set Approach (DRSA) and represents the Decision Maker’s (DM’s) preferences with decision rules. The DM provides a set of pairwise comparisons indicating whether an outranking (weak preference) relation should hold for some pairs of reference alternatives. This preference information is structured using...
