The study presents the results of research aimed at the construction of
a model of the relationship between the physical properties of metal and
the types of toughening treatment and modifiers used in the modification
of BA1044 alloy.
Samples of melts were subjected to four variants of the heat treatment and to
five types of modification. Studies of the samples consisted in
measurements of five physical parameters. Consequently, it was necessary
to seek a relationship between the nine input parameters and five output
parameters. With this number of the variables and a limited number of
samples, searching for the relationships by way of statistical methods
was obviously impossible, so it was decided to create an approximate
model through the use of fuzzy logic. This study describes the process
of creating a model and presents the results of some simulation
experiments that confirm the validity of the correct approach.
