   Software Description

PRS-CL supports the definition of real-time, continuously-active, intelligent systems that make use of procedural knowledge, such as diagnostic programs and system controllers. Its architecture consists of (1) a database containing current facts and beliefs, (2) a set of goals to be achieved, (3) a set of plans or procedures describing how certain sequences of conditional tests and actions may be performed to achieve certain goals or to react to certain situations, and (4) an interpreter that manipulates these components to select and execute appropriate plans for achieving the system's goals.

   Associated Projects
MPA

Multiagent Planning Architecture
MPA is an open planning architecture that facilitates incorporation of new plan-related technologies, capitalizing on the benefits of distributed computing for efficiency and robustness. MPA provides protocols to support the sharing of knowledge and capabilities among agents involved in cooperative problem solving. MPA has been demonstrated in the air campaign planning domain, and was used as the infrastructure for the flagship demonstration of the DARPA Planning Initiative.

SUO-PDA

Planning and Decision Aids for Small Unit Operations
We developed a planning and decision aid (PDA) for the DARPA Small Unit Operations (SUO) program, to show the feasibility of using advanced planning technologies in SUO. The PDA monitors the execution of machine-understandable plans, using events as they are realistically reported in the battlespace, and alerts the user when the situation requires his attention.
