Hi.. Can anyone suggest me how can I solve conflict resolution on values ​​of the facts? It seems so simple but I have no idea in mind. The restriction is we don't know how many facts will be inserted, it could be one fact, 3 facts or more. My problem is: If my application suggested me 1 or * Persons() as best person, I have a conflict resolution and the rules to solve this conflict should be evaluate the best properties (values) of the facts. I don't know how to create rules to work with an amount of facts that I can't know and after to solve conflict resolution between values. The sample facts below show what I want to express as conflict resolution. Supose that I have a POJO Person(): atribute name; atribute experience; atribue age; atribute sugestedPerson; getters and setters; end Person *The declared rule is not explict. I can't express rule as:* rule "best experience" when $person : Person ( experience > 200 ) then $person.suggestedPerson = true; end or rule "best experience" salience 100 when $person1 : Person ( $exp1 : experience ) $person2 : Person ( $exp2 : experience ) $person3 : Person ( $exp3 : experience ) eval( $exp1 > $exp2 && $exp1 > $exp3) then $person1.suggestedPerson = true; end My knowledge Base was Built.. and 3 Persons facts was inserted into.. (*The problem is: - WE DON'T KNOW HOW MANY PERSONS WILL BE INSERTED IN THE KNOWLEDGE BASE*) Person { name = Jhon, experience = 200, age = 35, suggestedPerson = false } Person { name = Daniel, experience = 251, age = 27, suggestedPerson = false } Person { name = Julia, experience = 219, age = 31, suggestedPerson = false } Now I has 3 Persons and I want to sugest just the Person with the best experience, or if all persons has the same experience indicate the older person. What Can I do? In this Case the sugested person is: /Person { name = Daniel, experience = 251, age = 27, sugestedPerson = *true* }/ If all person facts has the same experience and was inserted: Person { name = Jhon, experience = 200, age = 35, sugestedPerson = false } Person { name = Daniel, experience = 200, age = 27, sugestedPerson = false } Person { name = Julia, experience = 200, age = 31, sugestedPerson = false } In this Case the sugested person is: /Person { name = Jhon, experience = 200, age = 35, sugestedPerson = *true* }/ *A sample rule will be helpfull* Daniel Souza - Brazil -- View this message in context: http://drools.46999.n3.nabble.com/Solving-Conflict-Resolution-on-values-o...
