“常规武器装备研制程序”的不足与改进

我国早期制定的《常规武器装备研制程序》,已不能适应当今武器装备研制过程中的可靠性和装备综合保障的新的观念和要求.现分析了原研制程序在这方面的不足,并提出修订研制程序的阶段划分并调整各阶段工作内容的建议;从根本上规范了武器装备研制工作,使其与装备综合保障工作同步进行和相互协调,以求所研制的武器装备交付部队使用后,能尽快形成战斗力.     

On the optimal detection of an underwater intruder in a channel using unmanned underwater vehicles

Given a number of patrollers that are required to detect an intruder in a channel, the channel patrol problem consists of determining the periodic trajectories that the patrollers must trace out so as to maximized the probability of detection of the intruder. We formulate this problem as an optimal control problem. We assume that the patrollers' sensors are imperfect and that their motions are subject to turn‐rate constraints, and that the intruder travels straight down a channel with constant speed. Using discretization of time and space, we approximate the optimal control problem with a large‐scale nonlinear programming problem which we solve to obtain an approximately stationary solution and a corresponding optimized trajectory for each patroller. In numerical tests for one, two, and three underwater patrollers, an underwater intruder, different trajectory constraints, several intruder speeds and other specific parameter choices, we obtain new insight—not easily obtained using simply geometric calculations—into efficient patrol trajectory design under certain conditions for multiple patrollers in a narrow channel where interaction between the patrollers is unavoidable due to their limited turn rate.© 2011 Wiley Periodicals, Inc.

对我军装备建设基本规律的再认识

通过对我军武器装备建设历程的回顾,结合学习毛泽东军事思想和邓小平、江泽民国防和军队建设思想,深入学习贯彻科学发展观以及胡锦涛同志关于武器装备建设的重要指示,系统总结武器装备建设的阶段性特点,对新世纪新阶段我军武器装备建设基本规律进行了新的归纳和总结。     

新时期武器装备建设新观念研究

新的历史时期,我军武器装备建设是一项综合性、整体性极强的系统工程,同时又是一项技术复杂、投入巨大、周期较长的建设工程。提出要在武器装备建设观念上实现4个“转变”:由“历时性”思路转向“共时性”思路,由需求牵引模式转向需求与能力复合牵引模式,由理论-实战(训练)途径转向以作战实验室为中心的途径,由单要素革新机制转向全要素体系创新机制。新观念的提出,为如何走出一条符合中国特色的武器装备建设跨越式发展之路提供了指导。

Coordinated replenishments from multiple suppliers with price discounts

In this study we present an integer programming model for determining an optimal inbound consolidation strategy for a purchasing manager who receives items from several suppliers. The model considers multiple suppliers with limited capacity, transportation economies, and quantity discounts. We propose an integrated branch and bound procedure for solving the model. This procedure, applied to a Lagrangean dual at every node of the search tree, combines the subgradient method with a primal heuristic that interact to change the Lagrangean multipliers and tighten the upper and lower bounds. An enhancement to the branch and bound procedure is developed using surrogate constraints, which is found to be beneficial for solving large problems. We report computational results for a variety of problems, with as many as 70,200 variables and 3665 constraints. Computational testing indicates that our procedure is significantly faster than the general purpose integer programming code OSL. A regression analysis is performed to determine the most significant parameters of our model. © 1998 John Wiley & Sons, Inc. Naval Research Logistics 45: 579–598, 1998
