Hello all,
A fine greeting to all,...
I would like to know the opinion and comment from various experts who
are actively engaged in Fuzzy logic rule based modeling, about the
possibility of integrating both the spatial and temporal data in
generating a rule set and developing a fuzzy model.
I have explore some of the possibilties but i am not certain about the
procedure I have adopted. I am working on an Environmental assessment
modeling based on Fuzzy logic rule based concept. One of the parameter
I have considered as an input variable is Rainfall, which is varying
temporally ( daily, monthly, yearly ) apart from other input
parameters like landuse, soil, slope, vegetation cover etc, which vary
spatially. The problem, I have is to asses how can I integrate both
the spatial and temporal variables in developing the Fuzzy Knowledge
base, (Rules and membership function).
If someone has experience such problem and has a ideas how to handle
such problem of temporal and spatial integration in Fuzzy rule based
modeling, I would be highly thankful to get the expert feedback and
directions and comments.
Thanks in advance,
Best Regards
Truly,
Bakim |

You should say where you see any problem. Rainfall is not time dependent,
it is a value. It would be likely a fuzzy value over some numeric domain
like milliliter of water per square centimeter. That this value is the
result of some function of some place on the Earth and clock is irrelevant
to the issue, as you consider the rainfall as an input. (It could be
different, if the inputs were rather the location coordinates and clock.)
Clearly, the decision made depends on the rainfall. It does not matter
whether this water fell at 15 or 16 October, again assuming that the time
is not an input. The laws of physics do not change with the calendar.
