"Tutorial":
We are sorry this release of our program is in Spanish, but please
consider it is a pre-alpha
version.
As an example, follow the next steps to do a fuzzy arithmetic computation:
1- Click on "Archivo"
2- Click on "Nuevo"
3- One can choose several types of fuzzy numbers. By now, select (i.e.,
e.g. double click on)
"Numero difuso trapezoidal" for a trapezoidal fuzzy number or "Numero
difuso
triangular" for a triangular fuzzy number.
4- You must write a name (without blanks, but you can use underscores) in
the box "Nombre"; it
will be the name of your fuzzy number.
5- The parameters of the fuzzy number are: "Izquierda" (left bound of
support), "Moda izquierda"
(left bound of the 1-cut=modal interval), "Moda derecha" (right ...) and
"Derecha" (right bound
of support).
6- Repeat the previous steps to introduce one more fuzzy number.
7- To perform a calculation, click on "Ver" and "Consola". There you can
type any expression
including the names of fuzzy numbers you defined and the operators:
+,-,*,/ and functions: log,
log10, exp, sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, >(a,b),
<(a,b), >=(a,b)...
8- If you want to see a graphical display of the result, click on "Ver"
and "Visor de
resultados".
9- In "Opciones" menu, you are able to change "Discretizacion"
(discretization level) and "Tolerancia" (tolerance level, that is, the
maximum difference value to consider equal two floating point numbers).
10- There are some other capabilities of the fuzzy calculator you can try,
but up to now, they
are not fully implemented (we hope to finish this application before
September).
This program will run under Windows95 OSR 2 or Windows NT 4.0.
We would be very grateful if you test this program and feedback any
comment about it.
