Consider the following three simple rules to represent fuzzy relationship between food quality and service in a restaurant as input variables and tip amount as output variables. 1) If the food is bad OR the service is poor, then the tip will be low 2) If the service is acceptable, then the tip will be medium 3) If the food is great OR the service is amazing, then the tip will be high. Given the membership functions illustrated in Figure 1 and 2 as follows. Food quality 1.0 Bad 0.8 Decent 0.6 Great 0.4 0.2 0.0 4 10 Service quality 1.0 Poor 0.8 Acceptable 0.6 Amazing 0.4 0.2 0.0 10 Figure 1. Food Quality and Service Membership Functions

Consider the following three simple rules to represent fuzzy relationship between food quality and
service in a restaurant as input variables and tip amount as output variables.
1) If the food is bad OR the service is poor, then the tip will be low
2) If the service is acceptable, then the tip will be medium
3) If the food is great OR the service is amazing, then the tip will be high.
