在求“变”中推进西南边防部队转型发展

西南边防部队驻防于我国西南边境地区,西起西藏自治区的日土县,东至广西壮族自治区的防城港市,担负着边防管控和边境防御作战等重要职能,在捍卫国家主权和安全中地位作用十分特殊。随着军队调整改革的深入落实,西南边防部队正处于转型重塑的关键时期,必须紧紧围绕新形势、新体制、新职能,着眼应急指挥、军事训练、边境管控、内外环境等关键要素和现实问题,在求"变"中推进创新发展,不断提升履职能力,切实为捍卫国家领土主权完整和维护边境稳定提供坚强保证。     

军民融合产业概念及范畴研究

军民融合产业概念及范畴不明确一直是困扰决策部门和研究部门的问题,影响了军民融合发展的顺利推进。本文在梳理总结军民融合产业概念及范畴的研究现状以及政府文件表述的基础上,认为军民融合作为一种发展模式,定义军民融合产业概念并非易事,但出于当前工作要求,需要相关管理部门整合力量,加强研究,尽快明确军民融合产业概念和范畴,构建科学合理的军民融合产业统计体系。     

国防领域技术预警流程研究

技术预警是对技术突破和由此引起的军事、政治、经济和社会危机的预测,是从国家安全的根本利益出发,以保持己方军事优势、防止敌人"技术突袭"为宗旨的技术发展预测。研究回顾了国内外技术预警研究历程,从前期准备、预警清单、技术调查、分析评估等四个主要环节,全面分析国防领域技术预警的具体流程,为国防领域技术预警系统的构建与应用提供支撑。     

在新时代对培育大学生综合国防素质的思考

综合国防素质是在适应世界军事变革发展和国家安全新需要的基础上,对传统国防素质的一次改进与提升。与传统国防素质不同,综合国防素质强调的是对综合国防意识、综合国防知识以及综合国防技能的掌握和运用。新时代,弘扬和培育大学生综合国防素质是贯彻党的十九大精神、落实国家教育事业"十三五"规划部署的重要举措,对加快实施人才强国战略、实现新时代强军目标发挥着重要作用。     

Multilateral defense cooperation in the Indo-Asia-Pacific region: Tentative steps toward a regional NATO?

Some U.S. military leaders have asserted that the United States, Japan, Australia, and India and the Republic of Korea are developing multilateral defense cooperation to deter aggression and uphold norms much like North Atlantic Treaty Organization (NATO) has in Europe. Frequent military exercises and China’s threats to freedom of navigation (FoN) and North Korea’s nuclear missiles comprise the motive force for such cooperation. However, cooperation thus far has been trilateral and minimal, given divergent national interests and dispersed geopolitical locations. Cooperation among Japan, Republic of Korea (ROK), and the United States is increasing given the threat, but ROK’s public opinion is divided about Japan. Australia, Japan, and India have increased cooperation with the United States but are reluctant to conduct FoN operations with the United States to challenge China’s expansionism in the South China Sea. If China becomes more aggressive and blocks FoN or seizes territory, development toward an Asian NATO is possible.     

雷达侦察效能对防空兵群抗击效率的影响评估

从信息化条件下防空作战的实际需要出发,描述了搜索雷达与火控雷达的侦察效能对群抗击效率影响的基本特点,运用概率论和防空兵射击指挥理论,建立了防空兵群分散指挥和集中指挥时,搜索与火控雷达发现目标概率对群抗击效率影响的数学模型,结合实例计算分析了选择射击指挥方式时搜索雷达发现目标概率的临界值。     

基于扩展Petri网的防空C~4ISRK系统建模分析

针对地空导弹武器系统防空中的火力分配问题,建立了战术级防空C4ISRK系统的Petri网模型。对其进行扩展,即联合谓词Petri网和赋色Petri网,建立旅级火力分配的改进模型,给出了具体的前置谓词公式。为有效分析战术决策的正确性提供了依据和思路。     

Optimal control policies for an inventory system with commitment lead time

We consider a firm which faces a Poisson customer demand and uses a base‐stock policy to replenish its inventories from an outside supplier with a fixed lead time. The firm can use a preorder strategy which allows the customers to place their orders before their actual need. The time from a customer's order until the date a product is actually needed is called commitment lead time. The firm pays a commitment cost which is strictly increasing and convex in the length of the commitment lead time. For such a system, we prove the optimality of bang‐bang and all‐or‐nothing policies for the commitment lead time and the base‐stock policy, respectively. We study the case where the commitment cost is linear in the length of the commitment lead time in detail. We show that there exists a unit commitment cost threshold which dictates the optimality of either a buy‐to‐order (BTO) or a buy‐to‐stock strategy. The unit commitment cost threshold is increasing in the unit holding and backordering costs and decreasing in the mean lead time demand. We determine the conditions on the unit commitment cost for profitability of the BTO strategy and study the case with a compound Poisson customer demand.     

Contracts and coordination: Supply chains with uncertain demand and supply

Considering a supply chain with a supplier subject to yield uncertainty selling to a retailer facing stochastic demand, we find that commonly studied classical coordination contracts fail to coordinate both the supplier's production and the retailer's procurement decisions and achieve efficient performance. First, we study the vendor managed inventory (VMI) partnership. We find that a consignment VMI partnership coupled with a production cost subsidy achieves perfect coordination and a win‐win outcome; it is simple to implement and arbitrarily allocates total channel profit. The production cost subsidy optimally chosen through Nash bargaining analysis depends on the bargaining power of the supplier and the retailer. Further, motivated by the practice that sometimes the retailer and the supplier can arrange a “late order,” we also analyze the behavior of an advance‐purchase discount (APD) contract. We find that an APD with a revenue sharing contract can efficiently coordinate the supply chain as well as achieve flexible profit allocation. Finally, we explore which coordination contract works better for the supplier vs. the retailer. It is interesting to observe that Nash bargaining solutions for the two coordination contracts are equivalent. We further provide recommendations on the applications of these contracts. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 305–319, 2016
