These are simple..

Fuzzy rules

1. If dirtness_of_clothes is Large and Type_of_dirt is Greasy then wash time is very long;
2. If dirtness_of_clothes is Medium and Type_of_dirt is Greasy then wash_time is long;
3. If dirtness_of_clothes is Small and Type_of_dirt is Greasy then wash_time is long;
4. If dirtness_of_clothes is Large and Type_of_dirt is Medium then wash_time is long;
5. If dirtness_of_clothes is Medium and Type_of_dirt is Medium
then wash_time is medium;
