Drools Planner (aka Optaplanner)

Drools planner is a planning engine that optimizes planning problems. It combines optimization heuristics and metaheuristics with very efficient score calculation.

What is a planning problem?

  • NP-Complete: any given solution to can be verified quickly (in polynomial time) but there is no known efficient way to locate a solution in the first place.
  • Has Constraints: Negative Hard Constraints (Must not be broken by a solution); Negative/Positive Soft Constraints (Could be broken by a solution).
  • Huge Search space

Domain Model

Planning Entity: class(es) that changes during the planning.
Planning Variable: The properties that change during planning. The set of possible values must be provided. 2 different approaches:

  • Values come from Solution: shared by all the Planning Entities in the problem.
  • Values come from Planning Entity property: The possible values are different for each Planning Entity.

Problem Fact: entities that don't change during planning but that are used to calculate moves and/or score.
Solution: data set containing all the planning entities.
Move: change (or set of changes) from a Solution A to a Solution B. (Not sure if it is mandatory to define these).

For the calculation of the score, Planner uses Drools.

Problem Facts

The following is the list of Problem Facts:

  • Patient
  • Provider (and all its sub-classes)
  • ProviderRole (PSYCHIATRIST, THERAPIST or SOCIALWORKER)
  • Severity (Patient's PTSD Severity: MILD, MEDIUM or SEVERE)
  • VisitDate
  • VisitType (GROUP, THERAPY, MEDICATION or COUNSELLING)

 

The number and type of Providers and Patients is fixed in the application:

SOCIALWORKER {id='S3', name='Mr. 3'}

The different providers associated to a Patient are never set by planner!

Planning Entity

Only 1 planning Entity is defined: Visit.
The current implementation starts with a predefined set of Visits for each Patient. The number and type of Visits depends on the Patient's severity:

  • MILD: 12 THERAPY, 4 COUNSELLING, 0 or 4 MEDICATION (randomly selected), 0 or 6 GROUP (randomly selected).
  • MEDIUM: 20 THERAPY, 6 COUNSELLING, 0 or 6 MEDICATION (randomly selected), 0 or 6 GROUP (randomly selected).
  • SEVERE: 30 THERAPY, 7 COUNSELLING, 0 or 7 MEDICATION (randomly selected), 0 or 6 GROUP (randomly selected).

As we can see, the Type and Patient of a Visit are fixed and never change during the planning.
The planning variables in this case are VisitDate and Provider.

Moves

VisitDateChangeMoveFactory: Creates all the possible combinations of Visits and Dates.
VisitTimeSwapMoveFactory: Creates a permutation of all the Visits to swap their Dates. (It is not clear to me if all these moves are not already included in the previous factory)
AssignCareProviderMoveFactory: Creates a combination of all the Providers for the different Visits.
