Industrial network flow involves three domains: infrastructure, individual subjects of movement, and planning and control of the movement. Examples include supply chain and intelligent transportation. These traditionally isolated domains can be digitally connected to enhance their performance. Digitization of the infrastructure provides real-time data to facilitate its operation, while digitally connecting the subjects to the infrastructure allows for tailored services and support to particular subjects. Connection of both to the enterprise information systems enables adaptive control for the application (e.g., logistics) at a global optimization level. Previous results in the field cover separate aspects of planning/routing, real-time monitoring, and trip support. Toward this end, a new highway-based Subject-Infrastructure-Enterprise information integration model using digital connection is proposed to the field of industrial network flow control for application to intelligent transportation and supply chain management. The SIE model supports industrial network flow control in a way comparable to an adaptive control panel administering an automated material handling system. In this metaphor, the global infrastructure becomes “controllable ” similar to factory conveyors and automated guided vehicles. The paper presents a conceptual design substantiated with information requirements analysis. An empirical experiment at locations in New York State shows the technical feasibility of the digital connection envisioned.

Research has shown that market-style selfscheduling is a promising approach to achieving real-time online resources allocation. However, the field still lacks sufficient results in areas such as control, inter-operation of heterogeneous data semantics, and qualitative performance measurement, to satisfy large scale distributed operations, especially today’s information enterprises. We propose a new agent-based, peer-to-peer publish and subscribe model for enterprise resource allocation under the above conditions. We use the proven industrial exchange technology to develop a full-fledged artificial market to self-schedule information tasks (resources offerings and requests) across a potentially extended enterprise, with a comprehensive performance-feedback-reallocation mechanism. New results also include an Agent-Base for creating and managing large number of custom agents online, a peer-to-peer negotiation method, and an open common schema design, to enable the model. It also provides an implementation scheme for developing the basic architecture, the pricing model, and the data interchange required of the artificial market.

Heterogeneous Distributed Database Management Systems (HDDBMS) involve the interoperability of data sources. One approach to achieve this type of integration is to build interfaces between the different databases being integrated. This approach holds, for a particular case, at a specific point in time. In this case however, the database structures need to be adapted. Such adaptation is not advisable since the local systems are usually important for their organizations. Therefore, an integration model that assures flexibility and scalability must be based on some knowledge of the underlying model of the different local databases. One solution is the use of the metadata concept, as a means to describe the logical and physical data characteristics. The metadata concept leads to the development of a Metadatabase system, which is viewed as a knowledge base about the local systems. The Metadatabase work at Rensselaer Polytechnic Institute (Troy, New- York) [11] and Universit'e Laval (Ste-F...

Abstract. The paper introduces the concept of software agent-oriented frameworks for global query processing in an interoperable environment. Such an environment is developed for the purpose of making cooperative interactions between several systems. These latter are distributed on networks and may present several incompatibilities. The global query processing is applied to the SIGAL project which aims at developing an interoperable environment for georeferenced digital libraries. This environment provides users with services that will free them from worrying about information distribution and disparities.

The advancement in computer network domain and the globalization of economy have forced enterprises to adopt a distributed structure which, in turn, implies a distribution of resources of those enterprises, particularly their information systems. Therefore, it is important to provide enterprises with integration tools to consolidate the information available throughout the distributed information systems and databases. One original approach to the integration problem that assures flexibility and scalability is the use of the metadata concept. This concept has led to the development of a Metadatabase system, that is, a knowledge base containing both logical and physical data characteristics of local systems. The Metadatabase may be seen as a specialized information warehouse which stores information about information systems, the data structures they use, and the mechanisms used to actually process and store the information. Based on the Metadatabase, a software infrastructure, the Rule...

Abstract: A truly natural language interface needs to be feasible for actual implementation. We developed such a new approach for database query and tested it successfully in a laboratory environment. The new result is based on metadata search, where the metadata grow in largely linear manner and the search is linguistics-free (allowing for grammatically incorrect and incomplete input). A new class of reference dictionary integrates four types of enterprise metadata: enterprise information models, database values, user-words, and query cases using an ontology-based meta-structure. The layered information models allow user-words to stay in original forms as users articulated them, as opposed to relying on permutations of individual words contained in the natural input. These properties make the approach scalable to the number of users and the size of the database. A graphical representation method turns the dictionary into searchable graphs representing all possible interpretations of the input. A branch-and-bound algorithm then identifies optimal interpretations, which lead to SQL implementation of the original queries. Query cases enhance the metadata and the search of metadata, as

Research Article “Digitally connected enterprises ” refers to e-business, global supply chains, and other new business designs of the Knowledge Economy; all of which require open and scalable information supply chains across independent enterprises. Connecting proprietarily designed and controlled enterprise databases in these information supply chains is a critical success factor for them. Previous connection designs tend to rely on “hard-coded ” regimes, which do not respond well to disruptions (including changes and failures), and do not afford these enterprises sufficient flexibility to join simultaneously in multiple supply chain regimes and share information for the benefit of all. The paper develops a new design: It combines matchmaking with global database query, and thereby supports the interoperation of independent databases to form on-demand information supply chains. The design provides flexible (re-)configuration to decrease the impact of disruption, and proactive control to increase collaboration and information sharing. More broadly, the papers results contribute to a new Information System design method for massively extended enterprises, and facilitate new business designs using digital connections at the level of databases.

Abstract. On-demand business/service and other emerging models for service enterprise integration all involve on-demand information exchan-ge. The best practices in the eld tend to rely on homogeneous semantics, which is dicult to achieve for independent databases owned by indepen-dent enterprises. Otherwise, the exchange tends to be limited at the level of le transfers. To overcome these limits and achieve on-demand pull of information resources at the global database query level, we develop a new information exchange model to extend previous global query results and cover independent databases. The new model provides a four-schema architecture to allow enterprises to oer the information that they wish to share with others (query for users), as well as request what they want (query for data). A central element is information matching; which has to unify the representation and processing of both oering and requesting queries, and integrate them with traditional global database query re-sults. We develop such a new information matching model in this paper.
