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。

In the POPF model, wind farm is modeled by the probabilistic wind farm model considering the reactive power-slip characteristic, and the inequality constraints include not only the unit output constraints, the ratio constraints, the voltage constraints and the line current constraints but also the reactive compensation capacity constraints in wind farm and the system climbing capacity constraints per minute. By introducing the NCP function, the KKT conditions of POPF system are transformed equivalently. Based on the transformed nonsmooth nonlinear algebraic equations, the FOSMM is used to determine the POPF model expressed by the numerical characteristic of variables. The model includes nonsmooth functions, so it can be solved by a semismooth Newton-type method based on the subdifferential.
概率最优潮流模型中,风电场采用考虑无功功率—滑加热器差特性的风电概率模型,不等式约束中除了机组出力约束、有载调压变压器变比约束、电压约束和支路电流约束,也考虑了风电场无功补偿容量约束、系统的分钟级爬坡能力约束;使用非线性互补函数将概率最优潮流的KKT条件转化为一组包含有不光滑函数的非线性代数方程组,然后基于一次二阶矩法确定了以待求量的数字特征表示的POPF模型,由于该模型包含不光滑函数,因此采用基于次微分的半光滑牛顿型方加热器法求解。

The pharmacologic data and chemical data were analyzed by stepwise regression analysis and 16 characteristic chemical variates were extracted, the quality of Evodia samples were graded in a series of four according to both sets of the pharmacologic data. A quality grading assessment scheme of Evodia samples by chemical ANN pattern recognition was then proposed and the results was satisfying.

There exits several MDO algorithms. But they are in our opinion either nonefficient or complicated. So we devised an algorithm called Subspace Approximation Optimization . In the SAO algorithm, the whole system is decomposed into one system-level optimization and several disciplinary optimizations so that a large and complicated problem can be divided into several easy-solving sub-problems. The coupling relationships and the coordination among disciplines are presented by equality constraints and these equality constraints are assigned to relevant disciplines. The optimums of design variables in system level optimization are transferred to discipline level optimization. The optimums of design variables in discipline level correspond to the point that is the nearest to the optimums of design variables in system level. If the optimums of design variables in system level are out of feasible region of discipline 1eve1, linear constraints can be built in the system level optimization using the design variable optimums obtained by the discipline level optimization. The system level optimization would improve the design of the whole system with these linear constraints.
目前,国内外已经发展出了多种飞机多学科设计优化算法,本文的重点是针对协同优化算法的不足,提出了子空间近似优化算法(Subspace ApproximatingOptimization,SAO),SAO算法中,整个系统的优化问题被分解成一个系统级优化和若干学科级优化,而各个学科之间的耦合与权衡关系则被当作等式约束,这些等式约束将被分配到各个学科级优化中去,系统级优化的任务是寻找整个系统的最优解,而学科级优化的目标函数是以系统级优化分配下来的设计点为圆心的超球半径的平方,因此,如果系统级优化分配下来的设计点在学科级优化可行域内,则学科级优化目标函数为0,反之,则学科级优化的最优点是系统级优化当前设计点距离可行域最近的点。

Inorganic Se could be transformed into organic Se after malt steeping, germinating and kilning, which not only satisfies human need but also keeps human being and animal from the overtaking of Se by malt.Malt was used as a carrier of Se, not only, for it's nutritious, edible and medicinal but also for it's useful in food industry, especially in brewing.
我们把麦芽作为富硒载体不仅因为麦芽营养价值高,而且兼有食用、药用、酿造用等多种用途,因而麦芽在食品工业中占有很重要的地位,特别是在酿造工业上,麦芽是酿制啤酒的主要原料。2001年我国啤酒产量达2200万吨,需麦芽300万吨,但由于国产啤麦制麦性能较差,麦芽的质量指标很难达到原轻工部部颁优级品的标准。
