Fuzzy Possibilistic Optimistic Criterion-A New Approach
نویسنده
چکیده
In this paper we consider decision making under uncertainty when the probability of the states of nature is not known a priori and the outcomes of each alternative are characterized only approximately. The fuzzy approach is very useful to handle such situations. Here we take into consideration both the best and the worst consequences of a decision problem. An optimist expects the best to occur and the worst not to occur. Based on this attitude of the decision maker a new fuzzy optimistic criterion (3-FOC) is constructed. This criterion is more realistic and it has been proved that when clear ranking of alternatives is not possible using the existing criterion it is always possible to clearly rank the alternatives using 3-FOC. Example is given to illustrate the same. AMS subject classification:

Resilient Supplier Selection in a Supply Chain by a New Interval-Valued Fuzzy Group Decision Model Based on Possibilistic Statistical Concepts
Supplier selection is one the main concern in the context of supply chain networks by considering their global and competitive features. Resilient supplier selection as generally new idea has not been addressed properly in the literature under uncertain conditions. Therefore, in this paper, a new multi-criteria group decision-making (MCGDM) model is introduced with interval-valued fuzzy sets (I...
متن کاملJournal of Uncertain Systems, Vol1 No3, 2007, August, World Academic Union (World Academic Press)
Conventional Fuzzy regression using possibilistic concepts allows the identification of models from uncertain data sets. However, some limitations still exist. This paper deals with a revisited approach for possibilistic fuzzy regression methods. Indeed, a new modified fuzzy linear model form is introduced where the identified model output can envelop all the observed data and ensure a total in...
متن کاملCREDIBILITY THEORY ORIENTED PREFERENCE INDEX FOR RANKING FUZZY NUMBERS
This paper suggests a novel approach for ranking the most applicable fuzzy numbers, i.e. $LR$-fuzzy numbers. Applying the $alpha$-optimistic values of a fuzzy number, a preference criterion is proposed for ranking fuzzy numbers using the Credibility index. The main properties of the proposed preference criterion are also studied. Moreover, the proposed method is applied for ranking fuzz...
متن کاملFormulation of general possibilistic linear programming problems for complex industrial systems
The current models and methods for PLP are usually restricted on some special types and usually the same type of possibilistic distribution. This paper focuses on linear programming problems with general possibilistic resources (GRPLP) and linear programming problems with general possibilistic objective coe cients (GOPLP). By introducing some new concepts of the largest most possible point, the...
متن کاملAssessment of Green Supplier Development Programs by a New Group Decision-Making Model Considering Possibilistic Statistical Uncertainty
The assessment and selection of green supplier development programs are an intriguing and functional research subject. This paper proposes a group decision-making approach considering possibilistic statistical concepts under uncertainty to assess green supplier development programs (GSDPs) via interval-valued fuzzy sets (IVFSs). Possibility theory is employed to regard uncertainty by IVFSs. A n...
