Library--An Electronic Ordering System.
Peer reviewed Peer reviewed
Waldstein, R. K. – Information Processing and Management, 1986
Presents a broad overview of the components that are needed to implement the "library" command, an online system command of the Library Network which allows American Telephone and Telegraph employees to access library services remotely. Types of requests that are handled are detailed and the library network environment is described. (MBR)

Knowledge Gateways: The Building Blocks.
Peer reviewed Peer reviewed
Hawkins, Donald T.; And Others – Information Processing and Management, 1988
Discusses the need for knowledge gateway systems to provide access to scattered information and the use of technologies in gateway building, including artificial intelligence and expert systems, networking, online retrieval systems, optical storage, and natural language processing. The status of four existing gateways is described. (20 references)…

Some Approaches to Modeling Complex Information Systems.
Peer reviewed Peer reviewed
Rao, V. Venkata; Zunde, Pranas – Information Processing and Management, 1982
Brief discussion of state-of-the-art of modeling complex information systems distinguishes between macrolevel and microlevel modeling of such systems. Network layout and hierarchical system models, simulation, information acquisition and dissemination, databases and information storage, and operating systems are described and assessed. Thirty-four…

Computer Terminal Memory Performance in a Resource Sharing Distributed Supercomputing Environment.
Peer reviewed Peer reviewed
Reddi, Arumalla V. – Information Processing and Management, 1983
Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Shared Memory Performance of Multi-Computer Terminals in Distributed Information Systems.
Peer reviewed Peer reviewed
Reddi, Arumalla V. – Information Processing and Management, 1984
Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…
