6. Rules 1. If (temperature is Cold) and (humidity is High) then (fan-speed is High) 2. If (temperature is Cool) and (humidity is High) then (fan-speed is Medium) 3. If (temperature is Warm) and (humidity is High) then (fan-speed is Low) 4. If (temperature is Hot) and (humidity is High) then (fan-speed is Zero) 5. If (temperature is Cold) and (humidity is Med) then (fan-speed is Medium) 6. If (temperature is Cool) and (humidity is Med) then (fan-speed is Low) 7. If (temperature is Warm) and (humidity is Med) then (fan-speed is Zero) 8. If (temperature is Hot) and (humidity is Med) then (fan-speed is Zero) 9. If (temperature is Cold) and (humidity is Low) then (fan-speed is Medium) 10. If (temperature is Cool) and (humidity is Low) then (fan-speed is Low) 11. If (temperature is Warm) and (humidity is Low) then (fan-speed is Zero) 12. If (temperature is Hot) and (humidity is Low) then (fan-speed is Zero)

7. Rules 13. If (sunlight is Morning) and (wind-speed is Low) then (Ventilation is Medium) 14. If (sunlight is Morning) and (wind-speed is Medium) then (Ventilation is Low) 15. If (sunlight is Morning) and (wind-speed is High) then (Ventilation is Very-Low) 16. If (sunlight is Mid-Day) and (wind-speed is Low) then (Ventilation is High) 17. If (sunlight is Mid-Day) and (wind-speed is Medium) then (Ventilation is Medium) 18. If (sunlight is Mid-Day) and (wind-speed is High) then (Ventilation is Low) 19. If (sunlight is Evening) and (wind-speed is Low) then (Ventilation is Medium) 20. If (sunlight is Evening) and (wind-speed is Medium) then (Ventilation is Low)

8. Rules 21. If (sunlight is Evening) and (wind-speed is High) then (Ventilation is Very- Low) 22. If (sunlight is Night) and (wind-speed is Low) then (Ventilation is Low) 23. If (sunlight is Night) and (wind-speed is Medium) then (Ventilation is Very- Low) 24. If (sunlight is Night) and (wind-speed is High) then (Ventilation is Very-Low) 25. If (error is P) then (blooming-control is VeryHigh) 26. If (error is Zero) and (change-in-error is Pos) then (blooming-control is MediumLow) 27. If (error is Zero) and (change-in-error is Zero) then (blooming-control is Medium) 28. If (error is Zero) and (change-in-error is Neg) then (blooming-control is MediumHigh) 29. If (error is N) then (blooming-control is VeryLow) 30. If (error is PL) then (blooming-control is High) 31. If (error is NL) then (blooming-control is Low)
