查询词典 cost-plus

An on-line blind source separation algorithm of non-stationary mixed signals is presented. The algorithm uses the multiple time-delayed decorrelation and natural gradient rule to obtain the stationary point of the cost function, only a small number of observed samples is needed to minimize the Frobenius norm of the correlation matrices, so the computing cost is low and continuous separation calculation could be realized by on-line operation.

利用一种基于多时延解相关准则的代价函数和自然梯度原则，分别推导出非平稳信号在瞬态线性混合及卷积混合情况下的在线盲分离算法，仅通过对有限个时延样本的相关矩阵进行Frobenius范数最小化运算得到分离矩阵，计算工作量小，无需对样本进行分块处理，可实现对信号的连续跟踪操作。

It should be the same important for inventory management in hospitals about inducing inventory cost and higher service level. Many researches have proved that EOQ /ROP model can decrease total inventory cost, but few discuss the impact on stockout.

在存货管理上，成本与服务是天平的二边，一昧的降低存货成本或提高服务水准都不是最适化的管理。1915年Harris提出经济订购量(Economic Order Quantity， EOQ)模式，以总成本最小的概念决定订购量，此理论也广泛的应用在各产业中。

The inventory cost is a primary component of the supply chain cost, and the method for multi-echelon inventory optimization and control must be adopted for the sake of the entire supply chain optimization and control, t present, papers on multi-echelon inventory systems have solved some problems, but they still have limitations. Firstly, they assumed that leadtime are constants. In practice, as the unknowable incidents exist in production, transportation and distribution processes, leadtime usually are uncertain. Secondly, there exist the hypotheses of totally back orders or completely lost sales under the condition of stockout in most literatures. Thirdly, the existing two-echelon inventory approximate model optimum always fixes one variable in the inventory strategy, and then seeks the optimal in the remained parameters, which makes the result can not be the best outcome.

目前有关两级库存优化控制的研究文献大多是假设提前期为常数的基础上建立模型，然而现实中由于供应链上各节点的库存不确定性以及运输、生产、交货等环节的不可预知性，使得提前期在多数情况下是不确定的；而且大部分文献都是假设缺货情况下要么完全延迟交货，要么完全损失销售，很少有考虑部分损失销售情况下库存优化控制的；另外，现有的两级库存近似模型的优化大都是固定一个库存策略中的变量，对余下变量寻优，其优化结果不可能是最优结果。

Proposed five ways on rate definition that use the economical principal as foundation and apply the marginal cost principal to discuss the rate system and its effect factors.

接着进行了确定收费水平的原则的探讨，应用经济学原理，提出了制定收费价格的5种方法，用边际成本原理讨论收费体系及影响因素，最后提出了具有成本劣加性特点的水资源经营性收费价格的修正公式。

In order to design a scheme to quantify the observation and to get the fusion estimation from the received bits,the estimation fusion problem was changed into that of decision fusion.The interval was divided into subintervals,each subinterval was assigned a hypothesis,suitable cost coefficients of each hypothesis was selected to form the Bayes cost functional,and a mapping from estimation fusion to decision fusion was constructed.

采用将区间划分，每一区间形成一个假设，规定假设之间合适的损失系数，将估计融合问题化为决策融合问题，运用成熟的决策融合的方法，对于现在研究还不成熟的估计融合传感器量化问题设计了一个解决方案，将决策融合的决策结果作为最终的估计，从而在观测被量化的条件下达到较优的估计效果。
