The amount of data speedily proliferates. Consequently, the excessive number of extracted association greatly prohibits to better assist the decision maker. In this respect, backboned on the Formal Concept Analysis, we propose to extend the notion of Formal Concept through the generalization of the notion of itemset aiming to consider the itemset as an intent, its support as the cardinality of ...

This paper demonstrates that vertical divestiture may increase consumer welfare even when the divestiture eliminates substantial scope economies and precludes only limited sabotage. More generally, the merits of vertical divestiture are shown to vary with: (1) the type and the intensity of competition in the retail market; (2) the locus of scope economies under vertical integration; and (3) the...

Managers nowadays face challenging decisions on daily basis and must weigh a growing number of factors while making such decisions. Previously, judgments were frequently assessed solely based single criterion, as profit or cost. Cost profit, the other hand, rarely captures desirability decision option. One most common popular research domains in science theory is multiple attribute (MADM) probl...

The claim arrival process to an insurance company is modeled by a compound Poisson process whose intensity and/or jump size distribution changes at an unobservable time with a known distribution. It is in the insurance company’s interest to detect the change time as soon as possible in order to re-evaluate a new fair value for premiums to keep its profit level the same. This is equivalent to a ...

Abstract This paper examines the incentive effect of a discontinuous and nonlinear compensation scheme, using the transaction data provided by two North American auto dealerships. Under the nonlinear scheme, a salesperson’s expected daily commission revenue critically depends on his position in the pay schedule on the day. We find that a measure of varying incentive intensity has a positive eff...

In this paper, we propose a fast intensity-based registration algorithm for the analysis of contrast-enhanced breast MR images. Motion between pre-contrast and post-contrast images has been modeled by a combination of rigid transformation and free-form deformation. By modeling the conditional probability function to be Gaussian and considering the normalized mutual information (NMI) criterion, ...
