In order to improve the support efficiency of spare parts for training equipment of space test forces， based on the idea of aerospace civil-military integration， an inventory model of spare parts for training equipment of space test forces based on information sharing and cross-level direct supply is proposed， and the existing spare parts inventory process is optimized to some extent. General to both is regarded as a system for the overall modeling， publishes a win-win goal， combined with the case fusion system dynamics simulation method，the current inventory model and the model proposed in this paper are simulated and analyzed. The results show that the inventory model established in this paper can effectively reduce the delay time of spare parts support and reduce the excessive production and storage of suppliers.It can achieve a win-win situation for both military and civilian in terms of improving spare parts support efficiency and reducing economic cost， and provide reference for improving spare parts support capability of training equipment of space test forces and promoting training level.

In order to meet the detonation control requirements of the aimable warhead during the fuze-warhead cooperation， a detonation control modeling method based on the detection and positioning of the hexagon laser fuze is presented for the dispersion rule of the prefabricated fragments of the aimable warhead. This method achieves the control of the detonation orientation of the aimable warhead by accurately recognizing the orientation of the target through the hexagon laser detection model. At the same time， in order to study the influence of different initiation methods on the performance of the warhead， the LS_DYNA finite element simulation software is used to simulate and study the fragments dispersion rule of the warhead under the different initiation methods and find the best initiation control position. Simulation results show that the directional fragment velocity gain under the eccentric 60° two lines Initiation is 9.32%， and the directional damage area is about 120°； the directional fragment velocity gains under eccentric 120° two lines， three lines and equidistant three lines initiation are 8.44%， 10.56% and 11.53%， respectively， and the directional damage area is about 60°. The established detection model can effectively cooperate with the detonation control of the aimable warhead to achieve the optimal damage effect on the target.

The optimization of operational test indexes plays an important role in simplifying test subjects， saving test resources and shortening test cycle. For the coexistence of a large number of qualitative and quantitative indicators in the operational test system， an optimization method of operational test index based on rough set and genetic algorithm is proposed. Based on the initial frame of operational test index system， the decision information table of operational test index system is built， and its attributes are reduced by rough set and genetic algorithm to obtain a simplified index set. The method is verified by a fire operational effectiveness test case of anti-aircraft gun weapon.
