TL;DR: An idealized language notation for a computer system whereby both data and instructions may be logically combined and operated upon utilizing a set of micro-instructions which have desirable algebraic qualities for this structural concept of a computer language and an embodiment is given of a structured computer architecture as discussed by the authors.
Abstract: An idealized language notation is disclosed for a computer system whereby both data and instructions may be logically combined and operated upon utilizing a set of micro-instructions which have desirable algebraic qualities for this structural concept of a computer language and an embodiment is given of a structured computer architecture. This set of micro-instructions lends itself to simple hardware realizations requiring minimal levels of logic. The nature of the hardware is highly amenable to realization with large scale integration techniques and should facilitate the emulation of a wide set of more specific machine language instructions. The disclosed hardware while simple is capable of decoding and performing a relatively large number of primitive logical operations, which operations are representative of the particular micro-program which originated same and which micro-programs are further combinable to perform all normal machine operations.

TL;DR: The general system requirements and specifications along with the hardware and software required to implement those requirements and Specifications are discussed.
Abstract: An integrated manufacturing process control system has been developed and implemented in several of IBM's manufacturing facilities to control process and test equipment used in the manufacture of IBM products. Thes system architecture consists of a central, on-line, IBM 360 Data Processing System operating under OS/360 which communicates via high-speed data channels to satellite IBM 1800, 1130 and System/360 processors. These satellite processors control various types of process and test equipment. The central system serves as a common data bank and an input/output device for the satellite processors. In addition, the central system performs data analysis and management reporting on information obtained fromt he manufacturing floor. This paper discusses the general system requirements and specifications along with the hardware and software required to implement those requirements and specifications. Also discussed are problems which were encountered after initial development and plans for future development.

TL;DR: To enable a controlled and timely introduction of all systems involved, an overall architecture was developed that encompasses all processes involved with train traffic, and cover all phases, from planning to supervision.
Abstract: In order to fulfil the expected increase in train traffic demand, Nederlandse Spoorwegen is making considerable investments in both expansion of infra-structure and in development of computer systems for better command of the production process. These systems encompass all processes involved with train traffic, and cover all phases, from planning to supervision. To enable a controlled and timely introduction of all systems involved, an overall architecture was developed. This paper describes the systems architecture and its parts.

TL;DR: The new Control Centre developed by DIMETRONIC S.A., has been conceived as a system capable of integrating as much as the functions performed in a modern railway traffic running, based on Architecture based on LAN Ethernet LAN protocol, TCP/IP PA-RISC machines UNIX environment.
Abstract: The new Control Centre developed by DIMETRONIC S.A., has been conceived as a system capable of integrating as much as the functions performed in a modern railway traffic running. The main characteristics of the system are: Architecture based on LAN Ethernet LAN protocol, TCP/IP PA-RISC machines UNIX environment Integration of functions Distributed process Operator's interface based on X-Windows High availability based on duplication of LAN and computers Easily expandable Conectivity to others systems under commercial standards User tools for data base and system configuration System configuration The system architecture consists of a dual Ethernet LAN, as shown in the figure, control computers, operators desks and communications computers. The system comprises 3 subsystems: Control and supervision It is a dual computer set in hot stand-by configuration. They performs the functions or subfunctions common to all the system. This set can be expanded according to the size of the network. Transactions on the Built Environment vol 7, © 1994 WIT Press, www.witpress.com, ISSN 1743-3509

TL;DR: A new graphical user interface, a uniform data model and future-proof system architecture so that simulators can be used more quickly, more effectively and in combination with one another and so they can be properly maintained.
Abstract: Netherlands Railways has developed several simulators, each of which has a separate aim, interface often deficient and not very efficient and storage format. Now it has decided to develop a new graphical user interface, a uniform data model and future-proof system architecture so that simulators can be used more quickly, more effectively and in combination with one another and so they can be properly maintained. This article describes the conceptual ideas, the architecture and several components such as the graphical user interface and the simulation database.
