Moderate to excellent entantio- and stereoselectivities (ee’s 54-100%) were observed in PLE catalyzed hydrolysis of (±)-ethyl 5-oxo-endo-tricyclo[5.2.1.02,6] deca-8-ene-2-carboxylate 5 and the structurally related open chain bicyclic structures (±)-ethyl 3-acetylbicyclo[2.2.1]hept-5-ene-2-carboxylates 7, 9 and (±)-ethyl 3-propanoylbicyclo[2.2.1]hept-5-ene-2-carboxylates 8, 10. A pronounced pref...

The aim of this paper is to study the integration of multiplicative preference relation as a preference representation structure in fuzzy multipurpose decision-making problems. Assuming fuzzy multipurpose decision-making problems under di4erent preference representation structures (ordering, utilities and fuzzy preference relations) and using the fuzzy preference relations as uniform representa...

In these notes, I will summarize the basic ideas in choice theory, which you must be familiar with from 14.121. I will describe three ways of modeling individual choice, namely choice function, preference, and utility maximization. I will present the conditions under which one can use each model. One can always use choice functions in modeling a decision maker’s choice at a given situation. In ...

In this paper, we investigate group decision making problems with multiple types of linguistic preference relations. The paper has two parts with similar structures. In the first part, we transform the uncertain additive linguistic preference relations into the expected additive linguistic preference relations, and present a procedure for group decision making based on multiple types of additiv...

Computational methods for discovering the preferences of individuals are useful in many applications. In this paper, we propose a method for learning valued preference structures, using a natural extension of so-called pairwise classification. A valued preference structure can then be used in order to induce a ranking, that is a linear ordering of a given set of alternatives. This step is reali...
