Design your monitoring system to get real benefits

You’re thinking of installing a new monitoring system – how do you decide what it needs to do?

The application of Health and Usage Monitoring Systems (HUMS) to Land Vehicles is a comparatively recent development. Although HUMS has been widely used on aircraft for many years and has proven to be effective, the lower repair costs and safety implications resulting from an unplanned failure on a land vehicle mean that it can be harder to make a case for HUMS on purely financial grounds. However, other factors such as the impact of HUMS on vehicle availability, spares holdings etc. may also be important criteria in evaluating the investment decision.

In order to help one of our customers decide on how (or even whether!) to fit a HUMS to their land vehicles, Avenca developed a Combined Operational Effectiveness and Investment Appraisal (COEIA) model. This model used information on how they operated, maintained, and supported their vehicles, as well as information on failure modes, potential monitoring and communication technologies, and financial data to produce a range of Key Performance and Financial Indicators. The customer was then able to use the model to rapidly evaluate a range of “what if” scenarios, in order to make an informed decision about the optimum solution to their particular monitoring system requirements.
