Planning time-critical course of action using point graph

The military decision maker is typically confronted by the task of checking the operational task temporal collaboration consistency in military planning, and that is a typical temporal reasoning problem. Point Graph (PG) is an efficient method for temporal reasoning. Thus, a PG is modeling for describing operational task temporal collaboration firstly, and then a consistency checking algorithm is given. Finally, an example is present to illustrate the feasibility and effectiveness of above method.
