When the demand for a skill outruns the supply, transaction leadership becomes insufficient, making other such approaches highly recommended.

当需求的技能outruns供应，交易的领导变得不足，决策等方式强烈建议。

This theory has remedied the deficiency of the domestic supply chain system research at present, and has important theory and realistic meaning.

该理论弥补了目前国内供应链研究领域中的不足，具有重要的理论和现实意义。

The positions and functions of the inventory control in the environment of supply chain are discussed first. The analysis on main conflict problems needed to be determined is presented. Based on the algebraic Petri nets the modeling research on vender managed inventory is proceeded on. Considering the shortages of the original algorithms, the improvements are putout to speed up the search process and improve the precision of the search results. The optimizations of lots sizing problem with the objective function of inventory costs are processed by the improved optimal algorithms. By the analysis on the results of the optimization, the conditions of overtime work, out of stock, and security stock are achieved.

文章首先讨论了供应链环境下库存控制在物流管理中的地位和作用，分析了库存控制需要解决的主要矛盾；然后应用代数Petri网对供应商管理库存(Vender Managed Inventory，VMI)的模式进行了建模研究；针对原始的粒子群优化算法和遗传算法存在的不足，分别提出了改进型算法，提高搜索速度和搜索精度；运用改进的优化算法对以库存成本为目标函数的批量计划问题进行了优化，通过优化结果的分析，得出了批量生产计划安排中加班、缺货和安全库存的存在条件。

Moreover, it is uncertain to increase the agricultural employment opportunity and the land of Taiwan is not enough to plant cane. How to achieve the goal of ethanol is still need to study.

此外，受限於国内耕地不足或者是耕地复耕可能性不高之因素，未来如何达到我国酒精供应目标仍有待研究。

Fourth, we need to boost agricultural supply and increase research spending, reversing years of agricultural underinvestment.

第四，我们需要扩大农业供应，增加研究支出，扭转多年来农业投入不足的局面。我们既不能成为卢德派分子（Luddite，译注：19世纪初发动骚乱并捣毁纺织机器的英国工人。

At the same, our country is trapped by the traditional planning economy and U.S.S.

但是目前我国重型机械制造企业由于长期受计划经济和前苏联生产模式的困扰，对物流在社会经济中的作用认识不足，物流基础设施落后，物流技术不发达，物流人才缺乏，多数对物流的研究存在急功近利的思想，且多将物流应用于供应与销售两大流通领域，而对企业内部物流、特别是生产物流，重视不够。

Aluminium prices started the second week of July with a spurt above US$3,300/t on the back of production woes coming from the Shanxi region in China. Previous attempts to breach the US$3,100/t barrier in June and May were short lived with prices not finding the support needed to stay above those levels. Aluminium bounced back with renewed strength in July on further power driven supply fears and new long positions entering the market. In June momentum came from production disruptions in UK (at the 145,000 tpy Holyhead smelter) and India (at the 360,000 tpy Angul smelter) and news that two smelters in the US (Glencore's 168,000 tpy Columbia Falls and Alcoa's 267,000 tpy Rockdale smelters) were curtailing their production levels on the back of prohibitive power prices. LME 3M prices tested the US$3,200/t level at the end of the month but the bulls appeared to hesitate to bridge that mark retreating towards US$3,150/t at the beginning of July.

中国山西的生产危机推动铝价在7月份第二周周初站上3，300美元/吨。5月份和6月份铝价试图突破3，100美元/吨的关口，但这仅是昙花一现，铝价并没有找到站上这个价位的支撑。7月份铝价反弹，电力危机引发供应担忧以及新的多头进场推动铝价走强。6月份，英国（年产能145，000吨/年的Holyhead冶炼厂），印度（年产能360，000吨的Angul冶炼厂）以及美国两座冶炼厂（Glencore公司旗下年产能168，000吨的Columbia Falls冶炼厂和Alcoa公司旗下年产能267，000吨的Rockdale冶炼厂）因电价上涨宣布减产，从而为铝价走势提供了动能。6月末，LME三个月期铝价格上探3，200美元/吨这一价位，但市场做多动力不足，铝价在7月初回调至3，150美元/吨。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
