This document discusses fuzzy logic and its applications. It provides an overview of fuzzy logic, fuzzy sets, and why fuzzy logic is used. It then gives examples of how fuzzy logic is applied in devices like cameras, washing machines, air conditioners, and more. It also discusses how fuzzy logic can be used in a temperature controller by defining temperature and humidity levels as fuzzy sets and controlling a heater fan speed based on that. The document concludes by covering judgmental biases that can occur in decision making and how being aware of these biases can help minimize their effects.

3. INTRODUCTION
• Applicable in embedded control and
information processing
• Simple way to draw conclusions
• In other words, resembles human decision
making with ability to work from approximate
data and find precise solutions
• Improve quality and development time

4. WHY ?????
• Alternative method, simple and faster
• Reduces design development cycle
• Simplifies design complexity
• Improves control performance
• Reduces hardware costs
• Simplifies implementation

5. Applications
 self-focusing cameras
washing machines that adjust themselves
according to how dirty the clothes
subway control systems
 Air conditioners
Rice cookers
Dishwashers and other home appliances

6. TEMPERATURE CONTROLLER
 The problem
 Change the speed of a heater fan, based off the room temperature
and humidity.
 A temperature control system has four settings
 Cold, Cool, Warm, and Hot
 Humidity can be defined by:
 Low, Medium, and High
 Using this we can define
the fuzzy set.

7. JUDGEMENTAL BIASES AND
CORRECTIVE PROCEDURES
• Strive to make accurate judgment possible..
Trapped by psychological inconsistency
• In other words , decision based on shortcuts
that are good most of the time
• These can be descreased or minimized if
become aware

8. JUDGMENTAL BIAS
• SELECTIVE PERCEPTION
Figure ground principle
Relevancy
• IMPRESSION EFFECT
primacy and recency effects
• PRESENTATION EFFECTS
• FRAMING EFFECTS
• CATEGORIZATION EFFECTS
