Rose-tinted lenses: how American functionalist strategy inhibits our appreciation of complex conflicts

Strategists and military professionals have previously questioned many of the methodological (theoretical underpinnings, the principles, and rules applied by the discipline) decisions associated with American military strategy, but the direction this essay takes is above and beyond the common methodological rivalries in how we pursue strategic desired future states. To get beyond methodological disputes entirely, we must consider thinking about our thinking as an organization on American strategy. Thus, this article hovers between philosophies, organizational theory, as well as our usually unquestioned belief in something called “strategy”. Questioning things about our basic understanding of the world tends to trigger strong organizational defense mechanisms, for good reason. Critical reflection at deep levels puts our worldview, and our role within it at stake. Nonetheless, as strategic disappointment emerges over multiple complex conflict developments, even the most cherished and guarded choices on how the world ought to work are ripe for critical inquiry. This essay examines the limited single strategic paradigm of the US defense industry and how the latest American National Security Strategy and Army Future Operating Concept (Win in a Complex World through 2030) presents a flawed strategic position. This essay presents valid alternative strategies that operate within different paradigmatic constructs.     

SEAD场景异构无人机配置与任务规划联合优化方法

对敌防空压制(suppression of enemy air defenses, SEAD)场景是多无人机协同的典型应用,针对该场景特点,在任务规划问题基础上将各类型无人机数量也作为决策变量,充分表征目标、任务和无人机的多种约束,建立异构无人机编队路径问题模型。设计了双层联合优化方法求解该模型：上层设计了任务衔接参数指标,精确评估各类型无人机需求,指导无人机配置调整;下层设计了改进遗传算法,高效处理多类型约束并能结合无人机数量变化对任务方案进行精细调整;双层相互协调获得满足需求的无人机配置和执行方案。仿真结果表明,该方法可以在避免遍历无人机配置组合的前提下获得合理的无人机配置方案和高效可行的执行方案。     

演化排列优化拉丁超立方设计方法

拉丁超立方设计是最常用的计算机试验设计方法之一,针对现有拉丁超立方设计方法采样一次性且难以兼顾设计的空间均匀性和计算效率的问题,提出了一种演化排列拉丁超立方试验设计方法。通过对小样本设计的演化、排列信息继承和扩充等操作,以较小的计算量实现了样本的扩充与优化。此外,所提方法可以兼顾现有样本和新增采样点之间的关系,实现样本的序列扩充,这在实际近似建模过程中十分方便。通过多组数值试验,验证了本文方法在空间均匀性和计算效率等方面的优越性。

The selection allocation problem

The Selection Allocation Problem (SAP) is a single period decision problem which involves selecting profit‐maximizing (or cost‐minimizing) activities from various distinct groups, and determining the volume of those activities. The activities in each group are selected subject to the availability of that group's resource, which is provided by either pooling or blending raw inputs from several potential sources. Imbedded in the decision process is the additional task of determining how much raw input is to be allocated to each group to form the resource for that group. Instances of this problem can be found in many different areas, such as in tool selection for flexible manufacturing systems, facility location, and funding for social services. Our goal in this paper is to identify and exploit special structures in the (SAP) and use those structures to develop an efficient solution procedure. © 1999 John Wiley & Sons, Inc.

Economic design of a two-stage control chart based on both performance and surrogate variables

The traditional approach to economic design of control charts is based on the assumption that a process is monitored using only a performance variable. If, however, the performance variable is costly to measure and a less expensive surrogate variable is available, the process may be more efficiently controlled by using both performance and surrogate variables. In this article we propose a model for economic design of a two-stage control chart which uses a highly correlated surrogate variable together with a performance variable. The process is assumed to be monitored by the surrogate variable until it signals out-of-control behavior, then by the performance variable until it signals out-of-control behavior or maintains in-control signals for a prespecified amount of time, and the two variables are used in alternating fashion. An algorithm based on the direct search method of Hooke and Jeeves [6] is used to find the optimum values of design parameters. The proposed model is applied to the end-closure welding process for nuclear fuel to compute the amount of reduction in cost compared with the current control procedure. © 1999 John Wiley & Sons, Inc.
