遥控武器站总体结构参数优化研究

为减小遥控武器站炮口扰动以提高射击精度,建立了遥控武器站部分机构参数化三维模型、有限元模型和刚柔耦合动力学模型。基于多学科集成优化软件ModelCenter进行了系统集成,以减小炮口扰动为目标,建立了遥控武器站总体结构参数优化模型。采用多目标遗传算法对总体结构参数进行了优化,优化后炮口振动状况明显改善,与位移相关的起始撼动和与速度相关的起始扰动分别较原方案降低了17.05%和19.04%。     

Screening and selection procedures with control variates and correlation induction techniques

We consider the problem of identifying the simulated system with the best expected performance measure when the number of alternatives is finite and small (often < 500). Recently, more research efforts in the simulation community have been directed to develop ranking and selection (R&S) procedures capable of exploiting variance reduction techniques (especially the control variates). In this article, we propose new R&S procedures that can jointly use control variates and correlation induction techniques (including antithetic variates and Latin hypercube sampling). Empirical results and a realistic illustration show that the proposed procedures outperform the conventional procedures using sample means or control variates alone. © 2012 Wiley Periodicals, Inc.

Optimal pricing for a short life‐cycle product when customer price‐sensitivity varies over time

Technology products often experience a life‐cycle demand pattern that resembles a diffusion process, with weak demand in the beginning and the end of the life cycle and high demand intensity in between. The customer price‐sensitivity also changes over the life cycle of the product. We study the prespecified pricing decision for a product that exhibits such demand characteristics. In particular, we determine the optimal set of discrete prices and the times to switch from one price to another, when a limited number of price changes are allowed. Our study shows that the optimal prices and switching times show interesting patterns that depend on the product's demand pattern and the change in the customers' price sensitivity over the life cycle of the product. © 2012 Wiley Periodicals, Inc.

面向任务的装备保障建模方法研究

针对面向任务的装备保障建模方法及其相关问题进行了研究,建立了面向任务的装备保障需求模型的基本结构,并从装备、弹药、油料、维修备件、维修人员这五方面讨论了模型的具体流程和算法。使用本文构建的装备保障模型,根据任务装备损坏数量和保障需求的关联关系,在已知装备战损、修复率和分布情况的基础上,结合装备弹药基数等信息,可以计算获得相关装备的保障需求信息,最后通过一个作战任务想定案例说明该模型的合理性和可行性。     

Estimating the point availability with right‐censored data

The point availability of a one‐unit system at a specified time is defined as the probability that the component is operating at that time. When both operating time and repair time are subject to random (right) censorship, we propose an asymptotic nonparametric approach for constructing confidence intervals for the point availability of the system. The technique is based on the fact that a product limit estimator converges to a Gaussian process. The method is also extended to finding confidence intervals for the point availability of a complex system using the δ‐Method. © 1999 John Wiley & Sons, Inc. Naval Research Logistics 46: 119–127, 1999
