Development of a Cost Benefit Analysis Method for Monitoring the Condition ofBatch Process Plant Machinery

摘要

While it is self-evident that large potential cost benefits exist for highcapital cost-high consequential loss plant, the scope for achieving realistic cost benefits for lower value, batch process equipment is less obvious and is also difficult to quantify. The results presented in this paper represents an attempt to determine a suitable basis for establishing cost benefits for plant machinery typified by that utilized for the manufacture of pharmaceutical products. In this preliminary investigation, a mathematical model has been devised for pump operation throughout the whole plant. It is based on actual data obtained over a five year period in which a maintenance cost prediction is established and the advisability of utilizing condition-based maintenance strategy is decided.
