Fuzzy Group Decision Making Using Surrogate Worth Trade-Off Method
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 8
Abstract
In this paper, fuzzy theory is used in group decision making problem. Surrogate worth trade-off method is discussed and according to fuzzy aspect of human decisions, linguistic variables are applied to state the Decision makers’ opinions. Applying linguistic variables enables proposed algorithm to deal with group decision making. Fundamentals of -constraint method, surrogate worth trade-off (SWT) method and linguistic variables are surveyed as predecessors of proposed algorithm. Proposed algorithm is explained step by step and finally, computability of proposed algorithm is demonstrated with a numerical example. This study shows that it is possible to use linguistic variables in order to group decision making applying SWT.
