车载UWB SAR干扰自适应抑制新方法

在分析车载超宽带合成孔径雷达(UWB SAR)探测系统中干扰类型及其产生机理的基础上,针对Tsaipei Wang等提出的批处理方法的局限性,提出一种基于迭代运算的图像域自适应干扰抑制方法.该方法利用基于韦布尔分布的恒虚警率(CFAR)检测器提高干扰信号估计的准确性;采用迭代方法在线估计和更新参数,实现干扰的自适应抑制.实测数据处理结果表明:该方法可有效抑制自信号干扰,且结构上适于实时处理,可满足车载UWB SAR探测系统对图像预处理的要求.

Modeling and analysis of a mixed‐model assembly line with stochastic operation times

We consider a mixed‐model assembly line (MMAL) comprised a set of workstations and a conveyor. The workstations are arranged in a serial configuration. The conveyor moves at a constant speed along the workstations. Initial units belonging to different models are successively fed onto the conveyor, and they are moved by the conveyor to pass through the workstations to gradually generate final products. All assembling tasks are manually performed with operation times to be stochastic. An important performance measure of MMALs is overload times that refer to uncompleted operations for operators within their work zones. This paper establishes a method to analyze the expected overload times for MMALs with stochastic operation times. The operation processes of operators form discrete time nonhomogeneous Markov processes with continuous state spaces. For a given daily production schedule, the expected overload times involve in analyzing the Markov processes for finite horizon. Based on some important properties of the performance measure, we propose an efficient approach for calculating the expected overload times. Numerical computations show that the results are very satisfactory. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Scheduling of depalletizing and truck loading operations in a food distribution system

This paper studies a scheduling problem arising in a beef distribution system where pallets of various types of beef products in the warehouse are first depalletized and then individual cases are loaded via conveyors to the trucks which deliver beef products to various customers. Given each customer's demand for each type of beef, the problem is to find a depalletizing and truck loading schedule that fills all the demands at a minimum total cost. We first show that the general problem where there are multiple trucks and each truck covers multiple customers is strongly NP‐hard. Then we propose polynomial‐time algorithms for the case where there are multiple trucks, each covering only one customer, and the case where there is only one truck covering multiple customers. We also develop an optimal dynamic programming algorithm and a heuristic for solving the general problem. By comparing to the optimal solutions generated by the dynamic programming algorithm, the heuristic is shown to be capable of generating near optimal solutions quickly. © 2003 Wiley Periodicals, Inc.

海警部队参与海上反恐作战的思考

随着各国加强对空中和陆地恐怖主义的防控，恐怖主义把视角转向海上。海上恐怖主义具有事件的突发性、手段的多样性、处置的复杂性等特点。边防海警部队参与海上反恐作战有利于取得海上反恐斗争的胜利，有利于掌握海上反恐主动权，有利于顺应国际海上反恐斗争的形势。针对海上恐怖主义的特点，边防海警部队应做到以下几点：一是平时反恐作战准备应具有超前性，二是参与海上反恐作战应体现实效性，三是参与海上反恐作战应把握全局性。
