Container Crane Control Applet

This applet illustrates a simple fuzzy expert system application. Upon loading the applet, the user simply has to input the crisp values for the crane head position (or distance) and the container sway (or angle) in the corresponding text boxes. After providing the inputs, he can select from the buttons provided:

• Clear. Choose this to clear the text boxes.
• Submit. Choose this to proceed with processing the crisp input values. The input values will be subjected to the fuzzification, inference, and defuzzification processes. Results of these processes are shown in a frame which pops up. Linguistic terms with non-zero membership values are highlighted. The results are also graphed together with the respective membership functions. The frame may be closed anytime by the user. It should be noted that the validity of the output values depends on the correctness and completeness of the rules stored in the rule base.
• Quit. Choose this to quit using the applet. This will disable all the fields visible and/or accessible from the interface.

Container Crane Control Application

The features of this program is just the same as that of the applet version. The applet version does not store and access domain-specific attributes and fuzzy rule base from files unlike this application version.
