 Select Factor analysis of interceptor capture probability Lei Chen, Zhijun Gu, Xianzong Bai, and Kebo Li Journal of Systems Engineering and Electronics    2011, 22 (6): 940-947.   DOI: 10.3969/j.issn.1004-4132.2011.06.010 Abstract （754）      PDF（pc） （806KB）（516）       Save The capture probability of interceptors has been deeply studied. Firstly, the definition of capture probability is analyzed. It is transformed into calculating the probability that the relative position vector between the target and the interceptor locates in a certain cone. The relative position vector and associated covariance matrix are projected in line-of-sight coordinates, and the 3-dimensional integral of a probability function in a cone is calculated to obtain the capture probability. The integral equation is a complicated expression of probability, and it is simplified to an explicit approximate expression according to some assumptions based on the characteristics of the engineering problems. The approximation precision is analyzed by comparative simulation difference, which indicates that approximate assumptions are reasonable. Utilizing the explicit  xpression, the characteristics of capture probability are analyzed respectively with the factors, such as the distance between the interceptor and the target, the precision of relative position vector, the maximum capture distance and the maximum field angle of interceptor seeker.

With the help of the shortest-tangent idea in route-planning and the algorithm of back reasoning from targets, a reference route algorithm is built on the shortest range and threat avoidance. Then a route-flight-time algorithm is built on navigation points. Based on the conditions of multi-direction saturation attack, a route planning algorithm of multi-direction saturation attack is built on reference route, route-flight-time, and impact azimuth. Simulation results show that the algorithm can realize missiles fired in a salvo launch reaching the target simultaneously from different directions while avoiding threat.

The accomplishment process of target assignment (TA) task is analyzed. A firing advantage degree (FAD) concept of fire unit (FU) intercepting targets is put forward and its evaluation model is established by using a linear weighted synthetic method. A TA optimization model is presented and its solving algorithms are designed respectively based on ACO and SA.

 Select 3D multipath planning for UAV based on network graph Xin Liu, Chengping Zhou, and Mingyue Ding Journal of Systems Engineering and Electronics    2011, 22 (4): 640-646.   DOI: 10.3969/j.issn.1004-4132.2011.04.013 Abstract （768）      PDF（pc） （2920KB）（850）       Save According to the characteristic and the requirement of multipath planning, a new multipath planning method is proposed based on network. This method includes two steps: the construction of network and multipath searching. The construction of network proceeds in three phases: the skeleton extraction of the configuration space, the judgment of the cross points in the skeleton and how to link the cross points to form a network. Multipath searching makes use of the network and iterative penalty method (IPM) to plan multi-paths, and adjusts the planar paths to satisfy the requirement of maneuverability of unmanned aerial vehicle (UAV). In addition, a new height planning method is proposed to deal with the height planning of 3D route. The proposed algorithm can find multiple paths automatically according to distribution of terrain and threat areas with high efficiency. The height planning can make 3D route following the terrain. The simulation experiment illustrates the feasibility of the proposed method.
 Select State feedback control of network-based systems with packet disordering Jinna Li, Shiqian Han, Meng Zheng, Haibin Yu, and Qingling Zhang Journal of Systems Engineering and Electronics    2011, 22 (2): 306-313.   DOI: 10.3969/j.issn.1004-4132.2011.02.018 Abstract （1060）      PDF（pc） （489KB）（755）       Save A new method that stabilizes network-based systems with both bounded delay and packet disordering is discussed under the state feedback controller. A novel model, fully describing the dynamic characteristic of network-based systems with packet disordering, is constructed. Different from the existing models of network-based systems, the number of delay items is time-varying in the model proposed. Further, this model is converted into a parameter-uncertain discrete-time system with time-varying delay item numbers in terms of matrix theory. Moreover, the less conservative stability condition is obtained by avoiding utilisation of Moon et al.’ inequality and bounding inequalities for quadratic functional terms. By solving a minization problem based on linear matrix inequalities, the state feedback controller is presented. A numerical example is given to illustrate the effectiveness of the proposed method.

 Select Modeling of combined Bayesian networks and cognitive framework for decision-making in C2 Li Wang, and Mingzhe Wang Journal of Systems Engineering and Electronics    2010, 21 (5): 812-820.   DOI: 10.3969/j.issn.1004-4132.2010.05.015 Abstract （819）      PDF（pc） （2440KB）（532）       Save The command and control (C2) is a decision-making process based on human cognition, which contains operational, physical, and human characteristics, so it takes on uncertainty and complexity. As a decision support approach, Bayesian networks (BNs) provide a framework in which a decision is made by combining the experts’ knowledge and the specific data. In addition, an expert system represented by human cognitive framework is adopted to express the real-time decision-making process of the decision maker. The combination of the Bayesian decision support and human cognitive framework in the C2 of a specific application field is modeled and executed by colored Petri nets (CPNs), and the consequences of execution manifest such combination can perfectly present the decision-making process in C2.
 Select Modeling for UAV resource scheduling under mission synchronization Jia Zeng, Xiaoke Yang, Lingyu Yang, and Gongzhang Shen Journal of Systems Engineering and Electronics    2010, 21 (5): 821-826.   DOI: 10.3969/j.issn.1004-4132.2010.05.016 Abstract （921）      PDF（pc） （451KB）（655）       Save Unmanned aerial vehicle (UAV) resource scheduling means to allocate and aggregate the available UAV resources depending on the mission requirements and the battlefield situation assessment. In previous studies, the models cannot reflect the mission synchronization; the targets are treated respectively, which results in the large scale of the problem and high computational complexity. To overcome these disadvantages, a model for UAV resource scheduling under mission synchronization is proposed, which is based on single-objective non-linear integer programming. And several cooperative teams are aggregated for the target clusters from the available resources. The evaluation indices of weapon allocation are referenced in establishing the objective function and the constraints for the issue. The scales of the target clusters are considered as the constraints for the scales of the cooperative teams to make them match in scale. The functions of the intersection between the “mission time-window” and the UAV “arrival time-window” are introduced into the objective function and the constraints in order to describe the mission synchronization effectively. The results demonstrate that the proposed expanded model can meet the requirement of mission synchronization, guide the aggregation of cooperative teams for the target clusters and control the scale of the problem effectively.

The truncation method, which is one of the techniques in the aeronautical data mining, can be used to efficiently handle the air-combat behavior data. The technique of air-combat behavior data mining based on the truncation method is proposed to discover the air-combat rules or patterns. The simulation platform of the air-combat behavior data mining that supports two fighters is implemented. The simulation experimental results show that the proposed air-combat behavior data mining technique based on the truncation method is feasible whether in efficiency or in effectiveness.
 Select Coordinated Bayesian optimal approach for the integrated decision between electronic countermeasure and firepower attack Zheng Tang1,*, Xiaoguang Gao2, and Chao Sun1 Journal of Systems Engineering and Electronics    2010, 21 (3): 449-454.   DOI: 10.3969/j.issn.1004-4132.2010.03.015 Abstract （706）      PDF（pc） （581KB）（445）       Save The coordinated Bayesian optimization algorithm (CBOA) is proposed according to the characteristics of the function independence, conformity and supplementary between the electronic countermeasure (ECM) and the firepower attack systems. The selection criteria are combinations of probabilities of individual fitness and coordinated degree and can select choiceness individual to construct Bayesian network that manifest population evolution by producing the new chromosome. Thus the CBOA cannot only guarantee the effective pattern coordinated decision-making mechanism between the populations, but also maintain the population multiplicity, and enhance the algorithm performance. The simulation result confirms the algorithm validity.
 Select Fuzzy distances based FMAGDM compromise ratio method and application Zhenfeng Rui1, 2 and Dengfeng Li2,* Journal of Systems Engineering and Electronics    2010, 21 (3): 455-460.   DOI: 10.3969/j.issn.1004-4132.2010.03.016 Abstract （801）      PDF（pc） （311KB）（437）       Save An extended compromise ratio method (CRM) based on fuzzy distances is developed to solve fuzzy multi-attribute group decision making problems in which weights of attributes and ratings of alternatives on attributes are expressed with values of linguistic variables parameterized using triangular fuzzy numbers. A compromise solution is determined by introducing the ranking index based on the concept that the chosen alternative should be as close as possible to the positive ideal solution and as far away from the negative ideal solution as possible simultaneously. This proposed method is compared with other existing methods to show its feasibility and effectiveness and illustrated with an example of the military route selection problem as one of the possible applications.

When weapon test data are insufficient, Bayesian analyses in small sample circumstance should be considered and the test data should be provided by simulations. The several Bayesian approaches are discussed and some limitations are founded. An improvement is put forward after limitations of Bayesian approaches available are analyzed and the improved approach is applied to assessment of some new weapon performance.
