5.4.3 Welding Procedure Using Rough-Set Theory
To obtain higher-quality welding products, welding procedures emphasize
control of parameters such as welding voltage, welding current, wire speed
rate, welding travel speed, room temperature, and work plate. Constraints of
the factors involved in the welding procedure are often vague and can cause
conflict. It is difficult for engineers to decide which factors are more important
than others when generating optimal schedules and designs. In this section, we
use a rough-set model to help engineers identify the important factors. The
dataset used in this section contains real-world data collected from a practical
production environment. ...
