This is an attempt to do a fuzzy calculator with statistical analysis
capabilities. Please send your comments to=20

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)=20
"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"=20
(left bound of the 1-cut=3Dmodal 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), >=3D(a,b)...=20
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.=20
We would be very grateful if you test this program and feedback any
comment about it.
