基于辩证语义的分布式协同态势分析方法

分布式协同态势分析在联合作战战役筹划中起着十分重要的作用。当前的战场环境呈现动态不确定性,传统的态势分析方法在处理不确定、不一致及不完全信息等实际应用中存在较大的局限性。本文基于辩论理论的辩证语义,提出了一种新的分布式协同态势分析方法。该方法通过多方对话博弈展现不同参与者的主张和论据之间的攻击关系及矛盾焦点,进而构建相应的辩证分析树网格以辅助决策者协同解决态势分析中的信息不一致和观点冲突问题。该方法的研究将为联合作战的态势分析提供新的方法论。

Contractual agreements for coordination and vendor‐managed delivery under explicit transportation considerations

We consider the coordination problem between a vendor and a buyer operating under generalized replenishment costs that include fixed costs as well as stepwise freight costs. We study the stochastic demand, single‐period setting where the buyer must decide on the order quantity to satisfy random demand for a single item with a short product life cycle. The full order for the cycle is placed before the cycle begins and no additional orders are accepted by the vendor. Due to the nonrecurring nature of the problem, the vendor's replenishment quantity is determined by the buyer's order quantity. Consequently, by using an appropriate pricing schedule to influence the buyer's ordering behavior, there is an opportunity for the vendor to achieve substantial savings from transportation expenses, which are represented in the generalized replenishment cost function. For the problem of interest, we prove that the vendor's expected profit is not increasing in buyer's order quantity. Therefore, unlike the earlier work in the area, it is not necessarily profitable for the vendor to encourage larger order quantities. Using this nontraditional result, we demonstrate that the concept of economies of scale may or may not work by identifying the cases where the vendor can increase his/her profits either by increasing or decreasing the buyer's order quantity. We prove useful properties of the expected profit functions in the centralized and decentralized models of the problem, and we utilize these properties to develop alternative incentive schemes for win–win solutions. Our analysis allows us to quantify the value of coordination and, hence, to identify additional opportunities for the vendor to improve his/her profits by potentially turning a nonprofitable transaction into a profitable one through the use of an appropriate tariff schedule or a vendor‐managed delivery contract. We demonstrate that financial gain associated with these opportunities is truly tangible under a vendor‐managed delivery arrangement that potentially improves the centralized solution. Although we take the viewpoint of supply chain coordination and our goal is to provide insights about the effect of transportation considerations on the channel coordination objective and contractual agreements, the paper also contributes to the literature by analyzing and developing efficient approaches for solving the centralized problem with stepwise freight costs in the single‐period setting. © 2006 Wiley Periodicals, Inc.

传统调和式态势估计方法在面对多源冲突数据时融合效果不佳。为此,提出一种基于冲突数据聚类的非调和式态势估计方法。首先利用迭代自组织数据聚类方法(ISODATA)对多源冲突数据进行聚类,然后利用频度和可信度对数据簇的重要性进行评估,最后得到态势估计结果。仿真结果表明,与传统态势估计方法相比,所提方法在融合多源冲突数据时能够得到可信度较高的态势估计结果。
