基于DEM的无人机炸点偏差测量模型

为了保证射击的精度和缩短作战反应时间,舰炮对远程岸上目标实施攻击时需要实时获取炸点相对于目标的偏差情况。目前我军现有的观察校射无人机所采取的炸点偏差模型在地形复杂地区存在较大的原理误差,为解决这一问题,提出了基于数字高程模型(DEM)的无人机炸点偏差模型,经误差仿真,复杂地形条件下该模型偏差测量精度和测量实时性都满足要求。     

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.

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.     

基于效用分析的武器装备发展方案决策

武器装备发展方案效用决策分析的目的就是以一定的方法和途径,根据决策者对武器装备发展所涉及的各项决策准则的偏好及其对各决策备选方案可能出现风险程度的态度,诱导出决策者对于各项准则的效用函数,从而以诱导的形式综合出各决策备选方案的综合效用,以获得决策者认为是最满意的决策方案.
