Hello everyone!

How can I compare 2 lists with a rule?

I upgraded my basic model to a more complex one now, but now I hit a wall. My WorkOrder have a List of skills, and my Engineer also have a list of Skills and I have to compare one with another.

Example:

Engineer A have skill ABC 1

Engineer B have skill ABC 2

Engineer C have skill ABC 3

WorkOrder A needs an engineer with skill ABC 3

WorkOrder B needs an engineer with skill ABC 1

WorkOrder C needs an engineer with skill ABC 2

The result should be this:

Engineer A will receive WorkOrder B

Engineer B will receive WorkOrder C

Engineer C will receive WorkOrder A

---------------

I am able to sort it by time, but not by skill, and I don't know how to loop over each list to find if one have the skills needed to fulful the other. These are my classes involved:

WorkOrder attributes:

--------

private int requiredWorktime;

private Priority priority;(enum)

private Severity severity;(enum)

private List<SkillWorkOrder> requiredSkills;

--------

Engineer attributes:

--------

private int worktime;

private String name;

private List<SkillEngineer> skillEngineerList;

--------

Skill attributes:

--------

private String name;

--------

both SkillEngineer and SkillWorkOrder are classes that simple receives the named class and a Skill:

Eg:

private Engineer engineer; //Or WorkOrder

private Skill skill;

Is it possible to iterate over these 2 lists, by drool rule, to check wich engineer have most coincidences with an workorder? (Eg: if and Engineer have skill ABC1, ABC2 and a WorkOrder needs an engineer with skill ABC1, ABC2 and ABC3 he would be choseng among the others because his skills)
