    The author explains the basics of system level design and discusses the evolution of design methods. A system complex enough to require system-level design tools is characterised typically by one or both of the following factors: concurrency within the system and randomness of input and output. He discusses randomness and concurrency then gives examples of systems that meet the criteria. He outlines the four key steps of system design: specifying the system; elaborating the design; evaluating design alternatives; and verifying that the design defined so far will produce the intended results. Finally, the author describes the features of Zycad Ltd.'s Endot range of system level tools View full abstract»

    The sequence of procedures that should be adopted are discussed. The first step is to carry out a feasibility study. This involves consultation with end-users, demonstrations, benchmark tests, and consideration of: future system upgrades, and enhancements; system obsolescence; enhancement of existing systems; software packages; and staffing. Once the feasibility study is complete and a budget approved, a detailed requirements specification can be drawn up. An invitation to tender (ITT) should then be drawn up. The elements a vendor should supply in their tender document are noted. The vendors are then shortlisted based on a technical evaluation, cost comparisons and consideration of contractual arrangements. Once an agreement has been reached with the vendor the system can be ordered, installed and acceptance tests carried out. Training and maintenance then become important View full abstract»

    Highlights one company's experiences in the use of off-the-shelf microcomputer-based equation-solving and spreadsheet packages, as well as customised programs written in FORTRAN and BASIC in order to assist the mechanical design and analysis of its products. Brown Brothers & Co. Ltd., based in Edinburgh, is involved in the design and manufacture of medium to heavy engineering mechanical systems for marine and offshore applications. These include ship stabilisation and steering-gear equipment, as well as motion compensators for use in offshore, oil-production platforms and vessels View full abstract»

    Describes a programme for technology transfer into four small companies. A Teaching Company Scheme, MIDAS, forms the vehicle to enable Associates to transfer or implement computer technology in manufacture in the companies. The companies associated with MIDAS (Manufacturing Industries Development Association in Surrey) are Vestec Ltd., Anthony H. Croucher Ltd., S.H. Muffett Ltd., and Pathtrace Ltd View full abstract»

  • Methods for the development of man-machine interfaces with application to CIM

    Publication Year: 1989 , Page(s): 59 - 64
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (480 KB)  

    CIM has the aim of integrating the design, development, planning, manufacturing and marketing processes by providing comprehensive information and user-specific solutions. The author examines the state of the art in the design and development of good user interfaces and highlights some of the features of the Papillon Prototype system developed under the ESPRIT research programme. The Papillon tool sets support both the development of CIM applications and the automatic generation of configurable, portable and friendly user interfaces View full abstract»
