Scheduling deteriorating jobs to minimize makespan

We consider a single-machine problem of scheduling n independent jobs to minimize makespan, in which the processing time of job J_j grows by w_j with each time unit its start is delayed beyond a given common critical date d. This processing time is p_j if J_j starts by d. We show that this problem is NP-hard, give a pseudopolynomial algorithm that runs in time and O(nd) space, and develop a branch-and-bound algorithm that solves instances with up to 100 jobs in a reasonable amount of time. We also introduce the case of bounded deterioration, where the processing time of a job grows no further if the job starts after a common maximum deterioration date D > d. For this case, we give two pseudopolynomial time algorithms: one runs in O(n²d(D − d) time and O(nd(D − d)) space, the other runs in p_j)²) time and p_j) space. © 1998 John Wiley & Sons, Inc.

Geopolitical Risks and Movements in Islamic Bond and Equity Markets: A Note

This study applies a non-parametric causality-in-quantiles test to examine the causal effect of geopolitical risks on return and volatility dynamics of Islamic equity and bond markets. Geopolitical risks are generally found to impact Islamic equity market volatility measures, rather than returns. However, geopolitical risks tend to predict both returns and volatility measures of Islamic bonds. Interestingly, causality, when it exists for returns and/or volatility of Islamic equities and bonds, is found to hold over entire conditional distributions of returns and volatilities, barring the extreme ends of the same.     

The Organization of the Defense Support System: An Economic Geography Perspective

In the context of restricted budgetary resources and the growing cost of maintenance, repair, and overhaul (MRO) activities, a major issue for modern armed forces is to sustain defense platforms. A possible method consists of realizing economies of scale through the concentration of maintenance activities, which involves the spatial reorganization of existing industrial sites dedicated to MRO. This article provides a formalized framework to discuss the optimal organization for the MRO of defense platforms in space. The public planner organizes the maintenance of defense platforms with only two possible spatial configurations. In the dispersed configuration, two industrial production units in charge of the maintenance optimally cover space, whereas in the concentrated configuration, a unique industrial unit covers space. Focusing on the tipping point between the two configurations, the balance of forces between agglomeration and dispersion in defense support activities is described and discussed. On the one hand, economies of scale provide an opportunity to optimize defense support costs, favoring concentration in a unique industrial unit. On the other hand, space causes dispersion to reduce both transport costs and operational social costs. This trade-off illustrates a general principle in spatial economics with an application to MRO production in the French case.     

基于红蓝对抗的实战化教学组训方法研究 —— 以航空兵初级指挥专业为例

红蓝对抗训练是实战化训练的最高形式,近年来在部队演习演练中被广泛采用,效果显著。军队院校教学向部队靠拢,向实战聚焦,可在航空兵初级指挥专业的人才培养中引入红蓝属性,开展实战化教学的探索和实践。本文提出“模拟环境+师生对抗+硬度可调”的实战化教学组训方法：一是红蓝对抗模拟训练环境,可支撑航空兵初级指挥专业学员开展“规划-部署-实施-评估”的航空兵作战全流程红蓝对抗实战化教学;二是“蓝”教员和“红”学员师生对抗教学组织实施程序;三是适应学员能力渐进式增长的关于训练想定、蓝军能力、导调方式和评定标准的“硬度可调”机制。此外,为确保红蓝对抗实战化教学的顺利实施,给出了锻造“红蓝兼备”院校“蓝”教员队伍的几点建议。     

Robust shortest path planning and semicontractive dynamic programming

In this article, we consider shortest path problems in a directed graph where the transitions between nodes are subject to uncertainty. We use a minimax formulation, where the objective is to guarantee that a special destination state is reached with a minimum cost path under the worst possible instance of the uncertainty. Problems of this type arise, among others, in planning and pursuit‐evasion contexts, and in model predictive control. Our analysis makes use of the recently developed theory of abstract semicontractive dynamic programming models. We investigate questions of existence and uniqueness of solution of the optimality equation, existence of optimal paths, and the validity of various algorithms patterned after the classical methods of value and policy iteration, as well as a Dijkstra‐like algorithm for problems with nonnegative arc lengths.© 2016 Wiley Periodicals, Inc.

陆军作战复杂系统ABMS机理研究

研究陆军作战复杂系统,需要解决两个不可回避的基本问题。一是怎样利用复杂性理论研究陆军作战系统的复杂性,即怎样借鉴复杂性理论构建复杂性思维模式。要解决这个问题,首先必须弄清复杂性理论概念的核心原理。二是在复杂性思维模式下,怎样进行陆军作战复杂系统的ABMS。要解决这个问题,首先必须弄清陆军作战复杂系统ABMS的机理所在。就这两个问题,在研究复杂性理论概念核心原理的基础上,构建了复杂性思维模式框架——复杂性分析二维结构,并由此探索了陆军作战复杂系统ABMS的机理:二维结构、"四个要素"、基本过程和陆战Agent模型框架,为陆军作战复杂系统的ABMS奠定了基础。
