Implementation of a business intelligence (BI) system requires considerable resources. Although, the BI market appears vibrant and the importance of BI is widely accepted, few studies have investigated the Critical Success Factors (CSF) that affects its successful implementation. There is an imperative for a CSF approach to enable BI stakeholders to focus on the key issues that lead to successf...

this paper proposes a bi-objective model for the facility location problem under a congestion system. the idea of the model is motivated by applications of locating servers in bank automated teller machines (atms), communication networks, and so on. this model can be specifically considered for situations in which fixed service facilities are congested by stochastic demand within queueing frame...

conclusion our study suggests that breast mri findings of igm have a wide spectrum. rim enhancement patterns are frequently seen on contrast enhanced images, but the imaging findings are nonspecific and cannot be used definitively to distinguish between benign and malignant lesions. patients and methods a retrospective analysis was conducted on 20 patients with igm who had been diagnosed by nee...

s at ICCAM 2008 CR Variants of Hybrid Bi-CG Methods for Solving Linear Systems with Nonsymmetric Matrices Kuniyoshi Abe Gifu Shotoku University 1-38, Nakauzura, Gifu, 500-8288 Japan [email protected] Joint work with: S. Fujino By Krylov subspace methods, we are solving a large sparse linear system Ax = b, where A stand for an n-by-n matrix, and x and b are n-vectors, respectively. The Bi-C...

l(bi, b + i , b − i ) = max ( 0, ρ+H(bi, b + i ))−H(bi, b − i )) ) , (1) whereH(·, ·) is the Hamming distance between hash codes, ρ is a margin between the Hamming distances of withincluster code pair {bi, b+i } and between-cluster code pair {bi, bi }. The hinge loss is a convex approximation to the 0-1 ranking error, which measures the network’s violation of the ranking order specified in the ...

Photoluminescence (PL) and excitation spectra of Bi melt-doped oxide and chalcogenide glasses are very similar, indicating the same Bi center is present. When implanted with Bi, chalcogenide, phosphate and silica glasses, and BaF2 crystals, all display characteristically different PL spectra to when Bi is incorporated by melt-doping. This indicates that ion implantation is able to generate Bi c...

Business intelligence and analytics (BI&A) has emerged as an important area of study for both practitioners and researchers, reflecting the magnitude and impact of data-related problems to be solved in contemporary business organizations. This introduction to the MIS Quarterly Special Issue on Business Intelligence Research first provides a framework that identifies the evolution, applications,...

Business-Intelligence-Systeme stellen durch ihre Unterstützung bei der Entscheidungsfindung für Unternehmen eine wichtige Rolle dar. Mit einer stetig dynamischeren Unternehmensumwelt geht daher die Anforderung nach der agilen Entwicklung dieser Systeme einher, so dass in der BI-Domäne zunehmend erfolgreich agile Methoden und Vorgehensmodelle eingesetzt werden. Die Weiterentwicklung und Anpassun...

There has been some confusion as to whether KM is part of BI or BI is part of KM. The lack of clarity is seen to be, in part, dependent on how the two concepts are defined. Both concepts promote learning, decision-making, and understanding. Yet, KM can influence the very nature of BI itself, especially since BI models often ignores the impact of tacit knowledge. Hence, this paper explains the n...
