Abstract. Standard representation of manufacturing capability information is a necessity for efficient configuration of loosely-coupled supply chains. ManuTerms is a formal thesaurus that provides a set of standard vocabulary that can be used for description of manufacturing capabilities. In this paper, a method is proposed for supplier characterization and classification guided by ManuTerms. The tools developed in this work use the capability narrative of manufacturing suppliers as the input and extract key concepts that refer to certain aspects of manufacturing capabilities in order to characterize and classify manufacturing suppliers. Through an experimental study, the supplier classification method was validated with respect to the level of agreement with human judgment.Keywords: supply chain interoperability, manufacturing capability, thesaurus, supplier characterization.
IntroductionEffective configuration and operation of distributed supply chains highly depends on the ability to meaningfully exchange engineering information among the supply chain members. The main body of research in supply chain information interoperability has been focused on information exchange among the supply chain participants after the supply chain is configured [1]. However, information interoperability in preconfiguration stages is equally important as it improves the quality of communication among suppliers when searching for appropriate manufacturing counterparts [2]. A significant portion of the information exchanged and consumed during the supply chain pre-configuration stages is related to the manufacturing capabilities that different suppliers can offer. Manufacturing capability of a supplier refers to the aggregate abilities, skills, and expertise a supplier can provide to the customers enabled by its internal and external resources. The existing models for manufacturing capability representation are often proprietary and unstructured or semi-structured without well-defined semantics. This has resulted in information loss and information ambiguity in supply chain communications. In order to streamline information exchange in the early stages of supply chain lifecycle, it is imperative to develop
