Comparative regional GDP analysis: case study of Croatia
Central European Journal of Operations Research - Tập 19 - Trang 319-335 - 2010
Elza Jurun, Snježana Pivac
The focus of this paper is the regional GDP analysis of Croatian Counties. It is a part of an extensive on-going scientific research about Croatian economic challenges within the global recession environment. Although, as EU accession country, Croatia is divided into three NUTS 2 regions, twenty one Croatian Counties show significant economic and social disproportions. In multiple regression model...... hiện toàn bộ
Designing performance incentives, an international benchmark study in the water sector
Central European Journal of Operations Research - Tập 18 - Trang 189-220 - 2009
Kristof De Witte, Rui C. Marques
Cross-country comparisons avoid the unsteady equilibrium in which regulators have to balance between economies of scale and a sufficient number of remaining comparable utilities. By the use of data envelopment analysis, we compare the efficiency of the drinking water sector in the Netherlands, England and Wales, Australia, Portugal and Belgium. After introducing a procedure to measure the homogene...... hiện toàn bộ
Human factors in a contemporary organization
Central European Journal of Operations Research - Tập 28 - Trang 579-587 - 2020
Krzysztof Hankiewicz, Gerhard-Wilhelm Weber
The presented paper concerns publications presented as part of XXXI International Seminar of Ergonomics. It presents basic information on ergonomics terminology. In addition, the development directions of the ergonomics research area in historical terms were shown. This is because, among other things organizing background for over 40 years International Ergonomics Seminars series in Poland. The se...... hiện toàn bộ

Robust portfolio optimization for banking foundations: a CVaR approach for asset allocation with mandatory constraints
Central European Journal of Operations Research - - 2023
Maria Cristina Arcuri, Gino Gandolfi, Fabrizio Laurini
AbstractThis paper focuses on an innovative asset allocation strategy for risk averse investors who operate on very long-time horizons, such as endowments and the Italian foundations of banking origin (FBOs). FBOs play a pivotal role in supporting economic, financial and sustainable growth in the long term. In the search for a model which optimizes FBO portfolio ch...... hiện toàn bộ
Transition towards sustainable mobility: the role of transport optimization
Central European Journal of Operations Research - - Trang 1-22 - 2023
Belma Turan, Vera Hemmelmayr, Allan Larsen, Jakob Puchinger
Although the concept of a transition towards sustainability has been introduced about 30 years ago, there is still a lack of progress. Transport emissions have not decreased in the last decade. However, they need to be reduced substantially to meet climate goals. The cornerstones of a transition can be summarized with the avoid-shift-improve paradigm: Traffic should be avoided as much as possible,...... hiện toàn bộ

Measuring carbon performance for sustainable green supply chain practices: a developing country scenario
Central European Journal of Operations Research - Tập 28 - Trang 1389-1416 - 2020
Sadia Samar Ali, Rajbir Kaur, Filiz Ersöz, Bothinah Altaf, Arati Basu, Gerhard-Wilhelm Weber
Carbon emissions due to economic activities are recognized to be global problem. Governments of all countries need to evolve environmental policies and practices for large-scale collective actions to regulate green house gas emission. Fuel quality standards for vehicles, stricter codes for construction, emission limits for industrial units and power plants are some of measures advocated to speed u...... hiện toàn bộ
Constrained Naïve Bayes with application to unbalanced data classification
Central European Journal of Operations Research - Tập 30 - Trang 1403-1425 - 2021
Rafael Blanquero, Emilio Carrizosa, Pepa Ramírez-Cobo, M. Remedios Sillero-Denamiel
The Naïve Bayes is a tractable and efficient approach for statistical classification. In general classification problems, the consequences of misclassifications may be rather different in different classes, making it crucial to control misclassification rates in the most critical and, in many realworld problems, minority cases, possibly at the expense of higher misclassification rates in less prob...... hiện toàn bộ
Modeling dependent credit rating transitions: a comparison of coupling schemes and empirical evidence
Central European Journal of Operations Research - Tập 24 - Trang 989-1007 - 2015
D. V. Boreiko, Y. M. Kaniovski, G. Ch. Pflug
Three coupling schemes for generating dependent credit rating transitions are compared and empirically tested. Their distributions, the corresponding variances and default correlations are characterized. Using Standard and Poor’s data for OECD countries, parameters of the models are estimated by the maximum likelihood method and MATLAB optimization software. Two pools of debtors are considered: wi...... hiện toàn bộ
