Abstract This paper focuses on managing product data in a distributed information infrastructure for a virtual enterprise. It exploits the emerging STEP standards as a common representation for exchanging product data within this infrastructure. A set of STEP services is defined that provide the capability for engineers to retrieve and edit parts or a product model and to integrate those edited parts back into the product model. A demonstration of these services as part of a National Industrial Information Infrastructure Protocols Consortium demonstration is then described. The paper ends by discussing lessons learned from this demonstration. It also discusses future plans for development of the STEP services.

Abstract Capturing design process is becoming an important topic of feature-based modeling, as well as in product data exchange, concurrent design, and cooperative design. Three critical issues on the modeling of design process are considered in this paper, namely, feature concepts, feature evolution, and the semantic consistencies of the states of product models. A semantics-based product model is introduced to facilitate the description of both conceptual and detailed models, and to maintain the semantic consistencies of product states. The process is represented by feature states and their evolution records. Feature type variation and prototype-based design are proposed to support feature evolution. A conceptual description of the design process and an example are given.

Abstract The ability to exchange and share product data between and within enterprises is essential for implementing the concepts of concurrent engineering as well as operating in a global market economy. STEP, the STandard for the Exchange of Product Model Data, is an international effort to standardize product information. Product information is used by manufacturing enterprise to design, produce, and maintain a product. The purpose of STEP is to prescribe a neutral mechanism capable of completely representing product data throughout the life cycle of a product. Data sharing can only be discussed in the context of a specific application. The scope of STEP data sharing architecture has progressed from a single shared facility to sharing multiple distributed facilities. This paper discusses the lessons learned from a prototype implementation of the mechanical part design process(es) captured in a network of heterogeneous computers and database management systems to allow for data exchange and sharing between and within an enterprise.

: Italy was the first western nation affected by the pandemic and was observed as a pilot case in the management of the new coronavirus epidemic. The outbreak of COVID-19 disease has been very difficult in Italy, on June 25, 2020 there are 239,821 total cases of which 33,592 deaths nationwide. Three lessons emerged from this experience that can serve as a blueprint to improve future plans for the outbreak of viruses. First, early reports on the spread of COVID-19 can help inform public health officials and medical practitioners in effort to combat its progression; second, inadequate risk assessment related to the urgency of the situation and limited reporting to the virus has led the rapid spread of COVID-19; third, an effective response to the virus had to be undertaken with coherent system of actions and simultaneously.

ISO19156 Observations and Measurements (O&M) provides a standardised framework for organising information about the collection of information about the environment.  Here we describe the implementation of a specialisation of O&M for environmental data, the Metadata Objects for Linking Environmental Sciences (MOLES3).MOLES3 provides support for organising information about data, and for user navigation around data holdings. The implementation described here, “CEDA-MOLES”, also supports data management functions for the Centre for Environmental Data Archival, CEDA. The previous iteration of MOLES (MOLES2) saw active use over five years, being replaced by CEDA-MOLES in late 2014. During that period important lessons were learnt both about the information needed, as well as how to design and maintain the necessary information systems. In this paper we review the problems encountered in MOLES2; how and why CEDA-MOLES was developed and engineered; the migration of information holdings from MOLES2 to CEDA-MOLES; and, finally, provide an early assessment of MOLES3 (as implemented in CEDA-MOLES) and its limitations.Key drivers for the MOLES3 development included the necessity for improved data provenance, for further structured information to support ISO19115 discovery metadata  export (for EU INSPIRE compliance), and to provide appropriate fixed landing pages for Digital Object Identifiers (DOIs) in the presence of evolving datasets. Key lessons learned included the importance of minimising information structure in free text fields, and the necessity to support as much agility in the information infrastructure as possible without compromising on maintainability both by those using the systems internally and externally (e.g. citing in to the information infrastructure), and those responsible for the systems themselves. The migration itself needed to ensure continuity of service and traceability of archived assets.

This chapter describes the key elements in the application of GERAM to the analysis of the virtual enterprise of a ship maintenance consortium, the ANZAC ship alliance. The ANZAC ship project built 10 ANZAC class guided missile frigates for the Royal Australian Navy and the Royal New Zealand Navy. The ships have a service life of 25 to 30 years in which changes are required to keep up-to-date with latest warfare. In this study, VERA was adopted as the generic enterprise reference architecture to guide the systematic study of the anatomy of the virtual enterprise. The issues of creating and managing the logistics and information infrastructure that are necessary to support successful operation of the virtual enterprise are examined. Particular models were created according to GERAM for the timely support of the projects as the virtual enterprise grew.

Management Approaches

The support of real collaborative virtual enterprise (VE) scenarios sets forward particularly interesting challenges in terms of distributed information management, regarding the proper sharing and exchange of information among preexisting autonomous enterprises. In order to address these challenges, it is necessary to achieve a comprehensive analysis of advanced information management approaches that can be applied in VE platforms. In this context, this chapter provides a representative survey of several VE-related information management standards, technologies, and existing approaches that can be applied to support future VE infrastructures.
