Implementing Planning As Tactical Reasoning

Abstract

I n this p a p e r we present a system (called MRG) for the development of planners that have t o work i n real-world, complex and unpredictable application domains. The i d e a underlying MRG is that domain independent problem solving architectures, instead o f featuring powerful but fixed control mechanisms, should provide powerful and flexible tools for the definition of domain dependent control mechanisms. Complex strategies and control mechanisms are uniformly represented an MRG b y tactics, explicit data structures that can be reused, modified, reasoned about and executed. A t the m o ment, MRG is being successfully used within a c o m plex real world application under development at IRS T.
