Mapping Economic Activity in the European Union: Do Ownership, Industry and Location Matter?
2020
The paper proposes a new method for analysing the structure and dynamics of economic activity undertaken by locally owned and foreign-owned companies within the European Union. We employ an unsupervised learning algorithm that generates a neural network depicted on Kohonen maps and offering a clustering of companies with a different ownership (local and foreign) from various industries and countries of the European Union during 2009–2016. The research methodology, based on a self-organizing map (SOM) algorithm, belongs to a class of neural networks trained to organize data so that unknown patterns may be discovered, thus leading to results that cannot be attained by more traditional cluster…
Assessing Cloud Infrastructure Costs in Communications-Intensive Applications
2012
By deploying cloud infrastructure services, companies strive at achieving faster time to market, improved scalability, lower up-front costs, and lower IT management overhead, among other benefits. However, in longer term, the use of cloud infrastructure may incur significant costs; furthermore, these costs depend both on the required infrastructure resources and on the mode of infrastructure deployment. Therefore, the choice of a particular deployment mode should be justified with a systematic analysis of the associated costs. In this paper, a model for assessing the costs of alternative cloud infrastructure deployment scenarios is introduced. This model decomposes the infrastructure costs …
Back-Propagation Artificial Neural Network for ERP Adoption Cost Estimation
2011
Published version of a chapter in the book: Enterprise information systems, vol 220, part 2, 180-187. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-24355-4_19 Small and medium size enterprises (SMEs) are greatly affected by cost escalations and overruns Reliable cost factors estimation and management is a key for the success of Enterprise Resource Planning (ERP) systems adoptions in enterprises generally and SMEs specifically. This research area is still immature and needs a considerable amount of research to seek solid and realistic cost factors estimation. Majority of research in this area targets the enhancement of estimates calculated by COCOMO family models.…
Cost analysis for a future helicopter for passenger transport
2015
Purpose - This paper aims to identify the parameters that influence the cost competitiveness of helicopter services for scheduled passenger transport on a regional area. Design/methodology/approach - The approach used is based on an analysis of demand and on a bi-level model (modal split model - service supply optimization model) optimization. Performance optimization in the supply of helicopter transport services is obtained by a sensitivity analysis on the recognized cost factors. Findings - The identification of the variation margins in the cost factors that might make an helicopter competitive for scheduled passenger services. Research limitations/implications - The inability to conside…
