Cooperating Policies
  • Policies do not work alone but cooperate by
    multiple techniques to achieve user goals
  • Policies may cooperate
  • by chaining pre-conditions and post-conditions
  • sharing of data/assertions
  • Found that designers had great difficulty in
    understanding dependencies between policies

Cooperating Policies

Cooperating Policies
  • Creation of trees to improve understanding of
    dependencies
  • Deontic values to allow tree to understand its
    own success in achieving goals
  • Obligation, Permission, Interdiction
  • Effective for feature interaction detection and
    resolution
  • features as goals with modulators
  • (especially Permitted value)
