基于遗传算法的协同多目标攻击空战决策方法

多机协同多目标攻击是未来空对空作战的一种重要形式。首先建立了多机协同空战的自主优势矩阵 ,并依据多人冲突决策理论构造了空战的总体优化指标向量 ,然后针对其他优化算法的不足 ,提出用遗传算法优化该指标向量 ,实现多机协同多目标攻击空战决策 ,最后对 2∶ 2空战进行了仿真。仿真结果证明了上述思想的正确性。     

An interactive procedure for selecting acceptable alternatives in the presence of multiple criteria

In this paper, we consider the multiple criteria decision‐making problem of partitioning alternatives into acceptable and unacceptable sets. We develop interactive procedures for the cases when the underlying utility function of the decision maker is linear, quasiconcave, and general monotone. We present an application of the procedures to the problem of admitting students to the master's degree program at the Industrial Engineering Department, Middle East Technical University. © 2001 John Wiley & Sons, Inc.

针对平面阵列雷达群目标检测问题,以矩形阵为例,详细分析方位向和俯仰向复单脉冲比虚部的统计特性;建立平面阵列雷达群目标检测模型,根据恒虚警检测原理推导复单脉冲比虚部的椭圆判决域,并利用复单脉冲比实部辅助判决,综合提出基于复单脉冲比的平面阵列雷达群目标检测算法。针对双目标情形进行仿真实验,结果表明:在较高信噪比、较大角度间隔以及幅度相当且相位差较大的条件下算法能够有效检测群目标。     

Impacts of sequential acquisition,market competition mode,and confidentiality on information flow

We investigate information flow in a setting in which 2 retailers order from a supplier and sell to a market with uncertain demand. Each retailer has access to a signal. The retailers can disclose signals to each other (horizontal information sharing), while the supplier can solicit signals by offering retailers differential payments as incentives for signal disclosure (vertical information acquisition). In the base setting, market competition is in quantity, and a retailer can fully infer the signal that the other retailer discloses to the supplier. We show that the supplier prefers to sequentialize the procedure for information acquisition. Moreover, vertical information acquisition by the supplier is a strategic complement to horizontal information sharing between the retailers to establish information flow. In the equilibrium, the retailers have no incentive to exchange signals, but system wide information transparency can be realized through a combination of information acquisition and inference. We further study the signaling effect, whereby the supplier utilizes wholesale pricing as an instrument to affect the retailers' inference of the shared signals, and price competition to explore their impacts on the supplier's preference for sequential acquisition and the sustainability of information flow.     

Meaning of working and expectations: a research on professional soldier candidates in Turkey

Previous studies on the relationship between individual’s enlistment decisions and their personal characteristics examined a number of variables such as age, marital status, gender, family background, geographical background, employment situation and education level. However, attitudes towards working, expectations from a good job and centrality of working are also important determinants in this process. This paper examines the profile of juveniles who seek a career as gendarmerie non-commissioned officers (NCO) in the Turkish Armed Forces and their attitudes and expectations towards working in general within the framework of Meaning of Working (MOW) researches. According to the results of the survey conducted with 500 NCO candidates in Turkey, learning something new, good relations with colleagues and employment guarantee are detected as the main expectations of juveniles who seek a career in military. Results also show that having a job is so important for these young people that they consider having a job even prior to their families.
