This demonstration of SRI's Continuous Planning and Execution Framework involves the generation, adaptation, and managed execution of the Air Campaign Plans within the scenario developed by SRI for TIE 97-1 of the Planning and Decision Aids program. The plans within this domain focus on attaining offensive and defensive Air Superiority within a designated region.
A high-level summarization of the demonstration is pictured below. The
timeline along the bottom of the diagram shows exogenous events that are
outside of the system's control. Above that, activities are organized along
three functional roles: the User, the Planner, and the Executor. The term
Planner is used generically to refer to a number of planning-related activities:
generative planning, replanning, plan repair. The Executor is active at
all times, monitoring the environment for both significant events that
will require responses and tasks or instructions from the user.
The demonstration begins with the user specifying air objectives for
a given campaign. The Planner generates a plan (see image below) to satisfy
those objectives relative to its current knowledge of the operating environment.
The completed plan is reviewed by the User who can recommend changes to
satisfy any outstanding concerns. The Planner then produces an updated
plan that incorporates the user's feedback. As planning proceeds, the Executor
monitors the environment for events that are relavent to the developing
plan. Receipt of an intelligence update that invalidates parts of the plan
will prompt a request that the Planner replan the affected portions of
Monitoring of the environment continues as execution of the plan commences.
At some point during the execution, notification is received that a pilot
has been downed. The system responds by instigating an appropriate activity
(such as dispatching a Search and Rescue mission). In addition to monitoring
for critical events of this type, the Executor tracks progress through
the execution of the plan to determine whether modifications are needed
in response to the status of the execution. For this particular demonstration,
situation assessment indicates that a planned breach of enemy IADS capabilities
is insufficient resulting in the dynamic modification of the plan to include
the establishment of a second breach before proceeding with further missions
for attaining air superiority.
