design this examples of fuzzy logic in a sequential manner. The design includes fuzzification, rule evaluation, aggregation, and finally defuzzification.

Example $1$: Temperature Control

Objective: Design a fuzzy logic system to control a heater based on room temperature.

Inputs:

Temperature $($in Celsius$)$

Linguistic Terms:

Cold, Comfortable, Hot

Membership Functions:

Triangular for each linguistic term

Rules:

IF Temperature is Cold THEN Heater is High

IF Temperature is Comfortable THEN Heater is Medium

IF Temperature is Hot THEN Heater is Low

Output:

Heater Level $($Crisp value after defuzzification$)$

Example $2$: Restaurant Rating

Objective: Evaluate the overall rating of a restaurant based on food quality and service.

Inputs:

Food Quality $($Poor$,$ Average, Excellent$)$

Service Level $($Bad$,$ Good, Outstanding$)$

Membership Functions:

Triangular for Food Quality

Triangular for Service Level

Rules:

IF Food Quality is Poor OR Service Level is Bad THEN Restaurant Rating is Low

IF Food Quality is Excellent AND Service Level is Outstanding THEN Restaurant Rating is High

Output:

Restaurant Rating $($Crisp value after defuzzification$)$
