Predicting and holding the BDR time of a materiel system exactly can bring great convenience to implement timing and exacting command for commanders. Meanwhile, it is important to the decision making of development and of future materiel, in the same way. Taking certain propelled type automatic weapon as an example, this paper sets up an exacting problem solving model for calculating BDR time based on a random network and carries out computation of it. Research results indicated that this method is feasible.展开更多
