基于排队论的维修资源需求分析方法

以装备维修过程为基础,应用排队论分析维修过程中各维修活动的基本关系,考虑多维修活动对维修资源需求的冲突问题,建立了维修过程的排队模型。以损伤装备平均修复时间不大于给定值为约束条件,以投入的维修资源总成本最少为目标,求解出维修资源需求。

行政程序证据制度的特点及功能分析

作为证据制度,行政程序证据制度与诉讼证据制度有共性,可以借鉴诉讼证据制度的合理内容。但行政管理的特殊性与行政行为的多样性决定了行政机关不应照搬繁琐而严格的诉讼证据制度。主要采用比较的方法对行政程序证据制度的特点及功能进行分析和探讨,表明行政程序证据制度是一类独立的证据制度。

An extensible modeling framework for dynamic reassignment and rerouting in cooperative airborne operations

Unmanned aerial vehicles (UAVs), increasingly vital to the success of military operations, operate in a complex and dynamic environment, sometimes in concert with manned aircraft. We present an extensible modeling framework for the solution to the dynamic resource management (DRM) problem, where airborne resources must be reassigned to time‐sensitive tasks in response to changes in battlespace conditions. The DRM problem is characterized by diverse tasks with time windows, heterogeneous resources with fuel‐ and payload‐capacity limitations, and multiple competing objectives. We propose an integer linear programing formulation for this problem, where mathematical feasibility is guaranteed. Although motivated by airborne military operations, the proposed general modeling framework is applicable to a wide array of settings, such as disaster relief operations. Additionally, land‐ or water‐based operations may be modeled within this framework, as well as any combination of manned and unmanned vehicles. © 2010 Wiley Periodicals, Inc.

日本预防街头犯罪对策与启示

在剖析解读日本街头犯罪＂预防对策＂的基础上,提出日本警察运用简单手段取得社会治安的理想效果。预防犯罪,在理念上把警方全包全责调整向组织牵头、协调联动和指导督促;在实践上完善警察牵头,以警察、政府相关部门、生产相关企业、新闻媒体和普通民众等广泛参与为基础的联动群防机制;在落实上不断加强高技术手段与原始方法相互补充的立体防范环境建设;在过程中尽量贴近现实需要,以完整的系统来控制街头犯罪,是降低预防犯罪成本、提高预防犯罪效率的捷径之一。     

A branch‐and‐bound‐based solution approach for dynamic rerouting of airborne platforms

This article is a sequel to a recent article that appeared in this journal, “An extensible modeling framework for dynamic reassignment and rerouting in cooperative airborne operations” [ 17 ], in which an integer programming formulation to the problem of rescheduling in‐flight assets due to changes in battlespace conditions was presented. The purpose of this article is to present an improved branch‐and‐bound procedure to solve the dynamic resource management problem in a timely fashion, as in‐flight assets must be quickly re‐tasked to respond to the changing environment. To facilitate the rapid generation of attractive updated mission plans, this procedure uses a technique for reducing the solution space, supports branching on multiple decision variables simultaneously, incorporates additional valid cuts to strengthen the minimal network constraints of the original mathematical model, and includes improved objective function bounds. An extensive numerical analysis indicates that the proposed approach significantly outperforms traditional branch‐and‐bound methodologies and is capable of providing improved feasible solutions in a limited time. Although inspired by the dynamic resource management problem in particular, this approach promises to be an effective tool for solving other general types of vehicle routing problems. © 2013 Wiley Periodicals, Inc.

Helping hands: civil–military cooperation and Italy's military operation abroad

In the Post-Bipolar Era the growing complexity of the military operations requires a new approach for the resolution of international crises. Since the end of the Cold War, peace support operations (PSO) have become the mainstay and principal occupation of most Western armies. At the same time, Italy has been one of the most important actors in such an area. The article focuses on the cooperation between military and civil components (a process called CIMIC) as a key variable in the Italian PSOs. We will analyse in detail the main lessons learned from past military interventions as well as the general context in which new tendencies are taking place. The maintaining of a minimum security frame becomes essential to fulfil activities ‘collateral’ to the mission: reconstructing services and infrastructure, food distribution, water and medication, law and order, de-mining, training of local forces, and supporting local institutions. These are the main tasks to obtain thrust and support from the population.
