Vol 10, No 5, Vibration Monitoring of Rotordynamic Pumping Machinery - A Case Study - P W Ilott and A J Griffiths, Division of Mechanical Engineering and Energy Studies, Cardiff School of Engineering, University of Wales
The potential benefits from pump vibration monitoring within UK industry are often not realised due to poor system design and inadequate management consideration. With the cost of pumping within the UK industrial sector estimated at £1000 million per year, the potential for savings, estimated to be between 10% and 15% of that figure, is enormous. Two vertical spindle water pumps, providing cooling water to a blast furnace, were analysed in a case study of historical vibration data. Analysis of historical data and corrective maintenance work highlighted the potential for vast improvements to the condition monitoring system. Simple measures, such as resetting alarm points relative to machine baseline vibration levels, and improving communication routes between system operators, and maintenance personnel, would lead to increased confidence, enhanced data interpretation and more accurate fault diagnosis.

Vol 10, No 5, Diagnosing Turbo-Generator Faults with a Rule-Based Expert System - Barun Chakrabarti, National Thermal Power Corporation Ltd and Kailash Nath Gupta and Gajraj Singh Yadava, Indian Institute of Technology, India
Expert systems (ES) have emerged as one of the prominent application areas of Artificial Intelligence (AI) technology. The use of knowledge-based expert systems is being explored for many potential tasks, one of these being the diagnosis of faults in machinery. The development is described of a rule-based ES for diagnosis of faults in turbo-generator units of thermal power plants. The various issues that were considered in building up the diagnostic knowledge base have been outlined, along with some results obtained by applying the developed system to actual plant problems. The software can act as a useful diagnostic tool and training module for power plant operators.

Vol 10, No 5, Benchmarking the Human Side of Management - John Scott, Scott Hayward Limited
Benchmarking is now a well-established aspect of the philosophies of Total Quality and Continuous Improvement. But until now there has been no effective method of applying its principles to human resource management. A process will be described which fills this gap. It overcomes the basic problem - measuring non-quantifiable management practices - by using group consensus evaluations. The process provides indices of all the main dimensions of human management, together with precise indications of strengths and weaknesses and reliable pointers to the needs for managerial action. The maintenance world is already familiar with the process in another application - AMIS, which is now the international standard for benchmarking maintenance practices and the management of physical assets. The technique described applies the same process to benchmarking the management of human assets.
