Assets are categorized by their level of criticality.
In order to achieve an acceptable level of criticality and enhance the reliability of the system, some improvement actions need to be proposed or initiated for medium, high and very high critical failure modes and components.
These are distributed, real-time, embedded systems and due to the level of criticality in their operation, they require a high-integrity development and verification process.
With these features, the "coaching team" was required to assign a level of criticality for each intervention, to have some quantitative estimate of the relative importance of every one.
The control messages in smart grid can be of different levels of criticality.
Different regions of the criticality matrix represent different levels of criticality for rolling stock components.
The goal is to de-escalate the situation and get back to lower levels of criticality.
Finally, the failure modes are prioritised or classified according to their levels of criticality and some preventive actions are proposed to improve the reliability of the system.
The failure modes according to the level of their criticality are categorised into five classes, namely very low, low, medium, high and very high critical.
A careful optimization procedure between the selected operating level of sub-criticality, the safety reactivity coefficients and the possible need for additional reactivity control systems seems, therefore, advisable during the early design phase of any ADS systems in order to assure a benign transient response of the particular ADS design under investigation to typical plant transient initiators.
15 Strategic signage was placed on the booth to remind passers-by of the criticality of tasks taking place within.
