APPLIED ARTIFICIAL INTELLIGENCE
Abstract
The elimination of international trade barriers, lower tariffs, and shifting centers of global manufacturing and consumption leads to new dynamics in intermodal shipping. Advanced technologies, and in particular, automated storage/retrieval systems (AS/RSs) for designing high-capacity automated container terminals, have been recently proposed as possible candidates for improving the terminal's efficiency and meeting the challenges of the future in marine transportation. In this article, the authors present an analytical statistical model for computing expected cycle time of split-platform AS/RS (SP-AS/RS), in order to reduce average handling time of this system. The accuracy of the proposed statistical model is validated by Monte Carlo simulation. The results show that the analytical model is reliable for the design and analysis of the SP-AS/RS.

World Review of Science, Technology and Sustainable Development
Abstract
This paper explores the development of long-term, close relationships that are likely to influence the relationship between Transnational Corporations (TNCs) affiliates and their local suppliers. Based on the interdependencies between six industrial foreign subsidiaries and 26 local suppliers, it is possible to conclude that the complementarity between local suppliers and their TNC clients depends on two dynamics: • on the technological trajectory created by the supplier towards the upper steps of the technological competence • on the technological trajectory created by the transmissive capacity of the TNC client that helps their suppliers on their organisational transformation. © 2008, Inderscience Publishers.

COMPUTERS & OPERATIONS RESEARCH
Abstract
This paper presents a very special cutting path determination problem appearing in a high precision tools factory, and provides two new heuristics for its resolution. Particular features of both the cutting process, and of the material to be cut, bring in a set of unusual constraints, when compared with other cutting processes, which confer additional complexity and originality to the problem. In particular, this is a matter of practical and economic relevance, since the solution methods are intended to be implemented in a real-life industrial environment. The concept of dynamic graph is exploited to deal with the arc routing problem under study, which is modelled as a dynamic rural postman problem. The constructive heuristics developed, the "higher up vertex heuristic" (HUV) and the "minimum empty path heuristic" (MEP) are tested with real data sets.

ENTERPRISE INTEROPERABILITY II: NEW CHALLENGES AND APPROACHES
Abstract
The development of information and communication technologies determined enterprises to adapt their way of undertaking business, from traditional practices to e-business. In this context, achieving seamless interoperability among heterogeneous entities becomes a critical issue. The goal of this article is to present an innovative two-layered operational infrastructure aiming at achieving seamless interoperability in shoe manufacturing up-stream segment, developed within the scope of CEC-made-shoe European Integrated Project.
