一体化联合作战中信息流作用研究 总被引:3,自引:0,他引:3
以复杂系统理论为基础,从动力学角度出发,阐述了如何以信息流变化为依据、以相空间重构为手段,对作战系统状态转移轨迹进行反演计算,进而预测态势发展趋势的构想。同时针对一体化联合作战的“联合增效”作用,讨论信息流协调作用对一体化联合作战组织结构有序度的影响,建立了基于信息流协调度评价的一体化联合作战要素优化组合模型。 相似文献

This paper studies a periodic‐review pricing and inventory control problem for a retailer, which faces stochastic price‐sensitive demand, under quite general modeling assumptions. Any unsatisfied demand is lost, and any leftover inventory at the end of the finite selling horizon has a salvage value. The cost component for the retailer includes holding, shortage, and both variable and fixed ordering costs. The retailer's objective is to maximize its discounted expected profit over the selling horizon by dynamically deciding on the optimal pricing and replenishment policy for each period. We show that, under a mild assumption on the additive demand function, at the beginning of each period an (s,S) policy is optimal for replenishment, and the value of the optimal price depends on the inventory level after the replenishment decision has been done. Our numerical study also suggests that for a sufficiently long selling horizon, the optimal policy is almost stationary. Furthermore, the fixed ordering cost (K) plays a significant role in our modeling framework. Specifically, any increase in K results in lower s and higher S. On the other hand, the profit impact of dynamically changing the retail price, contrasted with a single fixed price throughout the selling horizon, also increases with K. We demonstrate that using the optimal policy values from a model with backordering of unmet demands as approximations in our model might result in significant profit penalty. © 2005 Wiley Periodicals, Inc.

In this study, we propose a new parsimonious policy for the stochastic joint replenishment problem in a single‐location, N‐item setting. The replenishment decisions are based on both group reorder point‐group order quantity and the time since the last decision epoch. We derive the expressions for the key operating characteristics of the inventory system for both unit and compound Poisson demands. In a comprehensive numerical study, we compare the performance of the proposed policy with that of existing ones over a standard test bed. Our numerical results indicate that the proposed policy dominates the existing ones in 100 of 139 instances with comparably significant savings for unit demands. With batch demands, the savings increase as the stochasticity of demand size gets larger. We also observe that it performs well in environments with low demand diversity across items. The inventory system herein also models a two‐echelon setting with a single item, multiple retailers, and cross docking at the upper echelon. © 2006 Wiley Periodicals, Inc.

A key organizational challenge for all modern militaries is instituting an effective command-and-control (C2) structure for joint operations. China has been a relative latecomer to joint operations, with a persistent weakness in joint C2. Reforms launched in early 2016 sought to overcome this challenge by establishing a permanent two-level joint C2 structure. Although not a ‘tipping point’ that will lead ineluctably to stronger operational effectiveness, this reform is nonetheless an important milestone in an evolutionary process towards better PLA joint operations. The result could be added operational challenges for several of China’s neighbors and the United States. 相似文献
