An ontological approach to logistics

In today’s global market, the competitiveness of enterprises is strongly dictated by their ability to collaborate with other enterprises. Ontologies enable common understanding of concepts and have been acknowledged as a powerful means to foster collaboration, both within the boundaries of an individual enterprise (intra-enterprise) as outside these boundaries (inter-enterprise). This paper argues that the use of ontologies can be beneficial for enterprise interoperability in the logistics domain, to improve communication and foster knowledge reuse, to facilitate the integration of existing systems and to support the development process of software solutions. Our experience shows that the development of ontologies for logistics is not a trivial task, and guidelines and best practices are necessary in this domain, especially to bridge the gap between theory and practice. On the one hand, proper theoretical and methodological support for ontology engineering is necessary in order to deliver precise, consistent and well-founded solutions to the market. On the other hand, solutions to practical issues should be provided and not take too long to be produced in order not to be detached from the original real market needs. This paper proposes an ontological approach for logistics that balances the trade-off between precision and pragmatism, by combining top-down and bottom-up practices for ontology engineering. From a top-down perspective, we promote the reuse of existing general-purpose (upper) ontologies and specialize them for the purpose of logistics. From a bottom-up perspective, we reuse code lists and classifications that already exist in logistics to support the creation of instances of our upper level concepts. The paper also presents a representative fragment of our core ontology for logistics and identifies areas for further work in ontology engineering for logistics.
