Vol 12, No 1, Maintenance Management Systems: Objectives and Solutions - Norman Eason, Resource Management Systems Limited
This paper examines many of the topics which must be addressed in the selection process leading up to the installation of maintenance management systems. Whereas many other papers have covered salient areas such as functional capability, maintenance strategy and technology, the focus here is on the less obvious aspects such as system integration, the procurement environment, system evolution and specials. These often lack the consideration given to the more obvious areas and this paper was therefore written with the aim of promoting their inclusion in the check lists of procuring organisations.

Vol 12, No 1, A Decision Support System Prototype for Maintenance Management - Einar Lihovd and Christian Steinebach, MARINTEK and Magnus Rasmussen, Norwegian University of Science and Technology (NTNU), Trondheim, Norway
A concept for a next generation Decision Support System (DSS) for maintenance management is presented. Such a system will integrate information from other systems dedicated to process control, condition monitoring, diagnosis, maintenance planning, and production planning. The main challenge is to support a maintenance planner in the compilation of task schedules, where the focus is on condition-based maintenance tasks and on the optimal merging of these stochastic tasks with periodic maintenance and other pending tasks. A tree-based approach for decision analysis under uncertainty is presented, and a prototype implementing the methodologies is described. The prototype is developed using an agent-based approach for integrating distributed networked systems. The work is part of a strategic research project funded by the Norwegian Research Council, two oil companies, and MARINTEK.

Vol 12, No 1, Assessing the Effectiveness of a Maintenance Programme - Kari Laakso, VTT Automation, Industrial Automation, Finland
A model has been developed for aiding evaluation of the effectiveness of existing test and maintenance programmes of industrial plant. It combines analysis of the historical data on faults and repairs with analysis of the history of functional testing and preventive maintenance programmes. Using the method, the periodic tests and preventive maintenance actions during which the faults were detected are pinpointed. The two analyses are combined by calculating simple indicators of test and maintenance effectiveness.
The present model has been developed via pilot analyses of the effectiveness of maintenance of motor-operated closing valves and automatic protection systems in Finnish and Swedish nuclear power plants. The application has resulted in verification of the preventive action programmes and justification of changes in them from the point of view of system reliability and maintenance cost. The recommended changes are adjustment of the preventive action intervals and introduction of better actions. The analytical model can be adapted for other applications, such as to other technical systems or other types of power plant.

Vol 12, No 1, The Management of Assets: Stackers and Reclaimers at BHP, Newcastle, Australia - Craig Croxton and Clive McIntosh, BHP (Long Products Division), Australia
Large bulk material handling machines (such as stackers and reclaimers), which are exposed to external environments, deteriorate structurally as they age. The application of an asset management plan has provided the framework to review the condition and design of seven such machines in the sinter plant at BHP Newcastle. Anticipated in the business plan is the need to provide a safe working environment and to maintain the primary assets of the business. The scope of the activity and decision-making needed to manage the implementation of the plan was carried out by a small dedicated core team who ensured quality and cost-effective performance. Five major activities that have been undertaken include: structural repair, redesign and replacement; fatigue life evaluation; review of past and future operational requirements and review of operational and maintenance practices.
At a total cost of $700,000 the implementation of the asset management plan has provided assurance to BHP that the machines will be capable of providing reliable service for a further six years.
