The tag is used to define an output variable that can be used in a rule of a Tsk system.

Figure 3 indicates the output node, but not the choice of output variable.

Notice how each rule provides a result as a truth value of a particular membership function for the output variable.

Therefore there is a high degree of assurance that the output variable can be maintained at the desired level.

In the control systems one or more output variables of a system need to follow a certain reference over time.

This result in turn will be mapped into a membership function and truth value controlling the output variable.

This identifies the data and branch dependencies for each output variable or parameter.

Every process model has distinguished input and output variables, and it can be autonomous or controlled.

Start with the output variable, X, and the riskiness parameter, a.

Figure 6 indicates the output node, but does not indicate the choice of output variable.
