The commands introduced in this section are purposed to specify fuzzy sets and to encode data fields by fuzzy values. Typically the fuzzy commands have been hidden by the GUI, but if you are developing a user interface, then you should be familier with the commands.
The fuzzy tool operates with a fuzzy frame which includes membership functions and statistics and a graphic structure for the fuzzy tool as the following figure shows.
The frame includes three parts: a frame for membership functions, a frame for the min/max values and a graphic structure. The membership functions are handled as data fields in which the first value defines the type of the set and other values are function specific. The frame "ranges" includes the minimum and maximum values for fuzzy sets if the automatic initialization is used.
