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.

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.

Abstract
Economic factors and developments of information and communication technologies have forced SMEs to engage in new organizational structures. The emergent process oriented collaborative networks require integration between distributed and heterogeneous infrastructures. The aim of this article is to present the approach for business process integration and management developed for the footwear sector within the scope of an EU project. Lessons learned and an agenda for future research work are then described. A brief overview of relevant enabling technologies is also made.

Abstract
E-business has emerged as a key enabler for information integration and interoperability in collaborative networks. This paper presents a service-oriented approach towards creating an ICT platform for the footwear industry, which has been tested for specific business scenarios and answers industry requirements. Other related works are discussed and analyzed, emphasizing the innovative aspects and advantages of this initiative.

Abstract
The Digital Business Ecosystem paradigm emerged worldwide as an approach supporting the adoption and development of interoperable infrastructures among SMEs, supporting them to achieve their goals efficiently. The aim of this article is to present a novel three-layered approach towards the creation of a digital business ecosystem for the shoe manufacturing domain, following ebXML scenario and framework, and using open-source software. Relevant related works are also discussed, emphasizing the innovative aspects and advantages of this novel approach.

Abstract
The goal of achieving full interoperability is still not achieved, despite the high number of tools and infrastructures developed. The objective of this article is to present a framework aiming at supporting seamless interoperability in a business collaborative networked environment. An implementation example from the footwear sector validating the framework proposed is also described.
