  As a "system of systems (SoS)" and "network of networks", SoS is a typical multi-network and cross-domain linkage complex system, involving physical, cyber, cognition and even social domains. SoS experiments are the ways and methods to solve the SoS engineering research problem. Firstly, the SoS' thinking concepts such as wholly thinking, connected thinking, relicense thinking, and gaming thinking are identified in this paper. Secondly, the basic experimental methods such as big data analysis, model assistance, action simulation, and war gaming are summarized. Thirdly, four key issues are put forward which need more attention, namely "multi-focus experimental framework for human-machine synergy", "multi-domain network communication system of systems experimental background", "dynamic real-time monitoring of system of systems capability indicators", and "baseline experimental for multidimensional comparison evaluation". Finally, the possible future development direction of SoS experimental engineering is discussed.

  System dynamic evolution is a cognitive foundation of structure optimization and effectiveness evaluation for formation system of systems (SoS). In view of entity heterogeneity of the formation, coupling of the system, and emergence of combat SoS, the paper firstly summarizes the evolution characteristics of surface ship formation. The evolution features are summarized from four aspects:information drive, function emergence, structural time change and overall correlation. Secondly, the elements of formation SoS are abstractly analyzed. The battle of surface ship formation is divided into two stages, prewar growth and war confrontation, for architecture abstraction. Thirdly, a hypernetwork model of formation SoS is established, and the conceptual model and structure model of the hypernetwork are established from different perspectives. Lastly, task driven progressive evolution modeling and information driven radical evolution modeling based on hypernetwork are proposed. The evolution model is given calculation method of formation SoS. According to calculation example of formation combat, the evolution model can effectively describe the process of formation SoS combat dynamically and provide strong support for formation structure optimization and effectiveness evaluation.

  Aiming at the path planning problem of multiple unmanned aerial vehicles (UAVs) in passive localization, an unmanned aerial vehicle dynamic path planning method based on evolutionary depth neural network is proposed. Firstly, this method combines the differential evolution algorithm and BP neural network, and designs a learning path planning framework for UAV passive location based on evolutionary neural network. Then, angle of arrival (AOA) localization is used for the multiple UAVs, and an optimal training set is generated based on the Cramer-Rao low bound (CRLB) of target estimation. The optimized waypoints can be acquired from the learning behavior of the relative deployment between UAVs and target. Experimental results show that the unmanned aerial vehicle (UAV) based on the evolutionary neural network can greatly improve real-time performance and decrease location time.

  For the aircraft cluster scheduling problem in a limited space, the paper models the overall operation process first, then converts the model to a typical scheduling model, for which heuristic rules and an optimization algorithm are presented. The algorithm is divided into upper and lower levels. The upper layer is responsible for selecting parking space and take-off position in the limited area. The lower layer is responsible for the scheduling work of each single aircraft and returns the scheduling result to the upper layer, which adaptively adjusts the result accordingly. Then, the lower layer algorithm is recalled to verify whether the adjustments of stand and takeoff position can improve the quality of the solution. The result of the scheduling scheme is demonstrated. Compared withmanual arrangement, the method is more advantageous in both solving-time and solution quality. This method is of great significance to improve the efficiency of aircraft sorties.
