## Base Analysis Conditions

Figure 3: Base analysis conditions

The above scheme is a general one and is used when application determines availability of the respective functions. Possibility of performing some of the functions also depends on other factors (actual length of universe of discourse of a linguistic variable defined on a universe of discourse of real numbers by points A and D of all its linguistic values must be non-zero etc.). In case a function is available but some of the additional conditions are not met, a message box describing the problem is displayed.
