The use of Information Systems in Fault Diagnosis
نویسندگان
چکیده
Excessive downtime remains a problem for many organisations, particularly those using complex capital intensive manufacturing processes. To counter this, many use computerised management systems to support various aspects of their maintenance activities including breakdown diagnosis. This paper describes research that has been undertaken to investigate the effectiveness of maintenance information systems to support activities during machine breakdown. A survey has been conducted to investigate computerised management system applications from the user perspective. The survey was designed to solicit user opinion on effective maintenance user support and the usefulness of existing IT systems to various personnel. The combined survey results and literature review are used to inform the development of a pilot maintenance information system that will be evaluated in a future study.
