Alternative Action Plan Generator (A2PG) for elaboration an anticipated feedback

This paper proposes an original Alternative Action Plan Generator – A2PG, which predicts possible alternatives of the human action plans in which the human operators do not respect the safety rules. These alternatives build an anticipated feedback. Five parameters characterize A2PG. The creation of action plans is through algorithms of definition and generation of alternatives to prescriptions, taking into account possible failures to comply with the safety rules by operators. These failures are simulated by not taking into account the safety preconditions, necessary to accomplish safely a given task. An illustrative case with a riding lawn mower is proposed to apply the proposed tool and show its relevance.
