This paper investigates bilevel optimization models for demand response management, and highlights the often overlooked consequences of a common modeling assumption in field. That is, overwhelming majority existing research deals with so-called optimistic variant problem where, case multiple optimal consumption schedules consumer (follower), chooses an schedule that is most favorable electricit...

This paper describes the use of syntactical data fusion to computing possibilistic qualitative decisions. More precisely qualitative possibilistic decisions can be viewed as a data fusion problem of two particular possibility distributions (or possibilistic knowledge bases): the first one representing the beliefs of an agent and the second one representing the qualitative utility. The proposed ...

 Recently, Khodabakhshi and Aryavash have introduced a ranking method [Applied Mathematics Letters, 25 (2012) 2066-2070.], which is based on an optimistic-pessimistic approach of data envelopment analysis (DEA). This method ranks all decision making units according to a combination of their minimum and maximum possible efficiency scores which are determined by solving two linear programming mo...

The present study applies explanatory style theory and the content analysis of verbatim explanation (CAVE) technique toward examining the leadership behaviors and effectiveness of key Civil War generals. The results of our study suggest that relatively optimistic explanatory styles may lead to aggressiveness and risk taking while relatively pessimistic explanatory styles may lead to passivity a...

This paper proposes axiomatic foundations of expectation formation rules, by which deviating players anticipate the reaction of external players in a partition function game. The axioms single out the projection rule among the rules that depend on the current partition and the pessimistic rule among the ones that are independent of the current partition. This analysis suggests that the projecti...

Scientific realism, the position that successful theories are likely to be approximately true, is threatened by the pessimistic induction according to which the history of science is full of successful, but false theories. I aim to defend scientific realism against the pessimistic induction. My main thesis is that our current best theories each enjoy a very high degree of predictive success, fa...

Binary possibilistic utility unifies two previously proposed qualitative decision models: optimistic and pessimistic utilities. All these decision models have been axiomatized in a von Neumann-Morgenstern setting. These axiomatizations have shown the formal similarity of these qualitative utilities and expected utility. Unfortunately in this framework, the representation of uncertainty has to b...
