摘要:

Maintenance management has always required the manipulation of large amounts of data, and the development of more cost-effective processing, storage and database systems has brought the use of computers to the fore in this area. This article considers the evolution of specialised equipment maintenance, the capabilities of today's computer-aided maintenance systems and the emerging expert systems technology.

摘要:

Astec 3 is a general-purpose analogue electronic circuit simulation package developed in France and available on IBM and DEC VAX computers. Designed for DC, AC and transient analysis, the system stands as a rival to the widely used SPICE. This article, the first of two on the system, outlines the general features of the Astec 3 simulation language.

摘要:

This second article on Astec 3 deals with the system's powerful modelling facilities. In particular, it describes how Astec 3 allows the description of sub-circuits or processing elements, in the form of models, which can be used independently or nested within more complex models to simulate sophisticated systems associated with signal processing or control. Examples are given of functional and transfer function modelling, demonstrating how a high-resolution graphics terminal can be converted into an investigative tool capable of presenting experimental results in a manner similar to the familiar CRO and spectrum analyser.
