and Applied Analysis 3 by Fujimoto 3 and Liu and Chen 4, 5 with the functional analysis approach. As for b , in case X is convex compact, and S is convex compact-valued with and without the upper hemicontinuous condition, it has also been studied by Liu and Zhang 6, 7 with the nonlinear analysis methods attributed to 8–10 , in particular, using the classical RogalskiCornet Theorem see 8, Theore...

During the last two decades, the labour demand structure in Germany and other OECD countries has experienced a decrease in the demand for low skilled and a rise in the demand for highly skilled employees. The adoption of modern technologies in the production process as well as the growth of international trade are often regarded as the main driving factors behind this change. On the other hand,...

Purpose – to model demand-driven chain networks on basis of multiple Customer Order Decoupling Points (CODPs). Design/methodology/approach – literature study and a case study in dairy industry, based on in-depth expert interviews. Findings – four main underlying factors of CODP diversity are addressed and modelled. Research limitations/implications – the proposed multiple CODP models provide th...

In Italy, the transformation of government procurement began in 2000 with the model developed by Consip SpA (a public company owned by the Ministry of Economy and Finance) for all public agencies across the nation. The paper is aimed to reconstruct the path taken by the public procurement reform in Italy gradually evolving from a supply-driven to a demand-driven approach. The Italian procuremen...

The current methods of the development and implementation of a Data Warehouse (DW) don’t consider the integration with the business-processes (organizational-processes and theirs respective data). In addition to these current methods, based on demand-driven, data-driven and goal-driven, we will introduce in this paper a new approach to DW development and implementation. This new approach will b...

Collaborative tagging allows users to assign arbitrary keywords (or tags) describing the content of objects, which facilitates navigation and improves searching without dependence on pre-configured categories. In large-scale tagbased systems, tag recommendation services can assist a user in the assignment of tags to objects and help consolidate the vocabulary of tags across users. A promising a...
