<title>ABSTRACT</title>
<p>The paper presents a new approach for multi-agent replanning
based on Distributed Constraint Satisfaction (DisCSP)
and Graph planning techniques. In this approach, a new
distributed refinement strategy is proposed to construct a
graph plan for fixing errors occurred during the plan execution.
The strategy employs an "max-branching" heuristic
that can reduce the final graph plan size and allow faster
completion time for the graph construction. The graph plan
is then compiled into a DisCSP problem and solved using
a multi-variable version of the Asynchronous Backtracking
Algorithm. The approach is demonstrated with experiments
which show that distributed planning graph and CSP can
practically solve the replanning problems in a multi-agent
environment.</p>
