s1: and collecting the battlefield situation and the battlefield information.
The battlefield information in this embodiment includes time, place, enemy-me units, etc., which may be summarized and summarized by the expert.
S2: and determining node contents of the Bayesian network, causal relationships among the nodes and the probability of each node according to the acquired battlefield situation and battlefield information, and completing construction of the Bayesian network.
The node content takes a situation event as a core and comprises the following four types:
(1) and is used to represent the overall situation of the enemy's final target, such as whether the enemy is attacking attack, defending, holding, or withdrawing at this time.
(2) The overall situation corresponds to how to realize the sub-situation of the final objective of the enemy. For any state of the tree under the global state, it is composed of the corresponding sub-states, such as main attack, impersonation attack, support and mask when the global state is attack.
(3) And the operation actions executed under the condition that the enemy is in the subalpe situation, such as aggregation, maneuver, radar startup and shutdown and the like.
(4) The reason for triggering the global situation, such as the issuing of an attack command, is the decision of a commander on factors such as the comparison of the forces of the enemy and the my, the geographic advantages and the like; or the departure reasons of withdrawal may be that the forces are very different, or the loss is too large, etc.
When judging whether the enemy attacks, the enemy carries out attack decision taking factors of force comparison and firepower comparison into consideration, if yes, the enemy attacks, and if not, the enemy abandons the attack. The sub-situations possibly caused by the attack are assumed as attack Force, Mass aggregation and Missile Missile, and if the Missile is launched to trigger a combat action event, radar boot detection Rader is adopted. The causal relationship among the nodes can be determined by research and development scientific research personnel and military domain experts, for example, the global situation occurs due to the triggering reason of the global situation, and the reason of the sub-situation is the global situation.
In the probability distribution of the nodes, firstly, the prior probability of a top node without a parent node is determined to be P (V), and then, the appointed conditional probability P (V) is determined for a child node with the parent nodei|Pa(Vi)). In this embodiment the nodes have two discrete states False or True, and the expert specifies a conditional probability transition table for each node, as shown in fig. 2.
S3: and when the probability of a certain node in the Bayesian network changes, carrying out situation reasoning according to the Bayesian network, calculating the updated probability of each node, and evaluating the most possible situation of the current network.
