"My problem is: that I have several events. Each event separately
are not dangerous. But some combination are known to be
dangerous. What I want to do is to setup a knowledge base
containing what is safe and what is unsafe, supply information at
a time 'T' and check if it is dangerous or not. It it is neither
dangerous nor safe, then ask for an expert to click on YES it is
dangerous or NO it isn't. Update the bases for the next try.

Is it possible to do this using fuzzy logic ?"

Yes, it is, but fuzzy logic may not be necessary. If you simply
want to fill out what is essentially a big grid of all the
possible combinations of events and the events are fairly clearly
present or absent, then you just need to make an array that
covers all the possible combinations and fill them in as you go.
Recall from the array is straightforward (simply read the
contents in the appropriate cell) and only bother the expert for
information when the cell is empty. Keep in mind that such a
grid may become quite large, depending on the number of events in
question. Now, if your information on the presence/absence of the
events is vague then fuzzy logic may be called in to attack the
uncertainty.
