Raw materials purchase is one of the major part in a company purchasing activities , the determination of purchasing time , price and quantity has directly influence on business output and profit . this article discusses how to make decision on purchase price and time by means of the present value analysis in futures purchase of raw materials , and the numerical example with data obtained from reality is used as an illustration . in addition , the decision on purchase quantity and sensitivity of inventory costs to purchase quantity are also analyzed and discussed based on the economic order quantity model . it is shown that with its logic and applicability the present value analysis method can be applied to raw material futures purchase in practice , rationalizing decision - making and saving costs 原材料采购是企业采购工作中的主要组成部分，其采购时机、价格、数量的合理确定直接影响企业的产出效益.本文对原材料期货采购中如何借助于经济现值分析方法进行价格决策和确定采购时机进行了讨论，并给出了具体实际数据分析和说明.此外，还根据经济订购批量模型围绕采购数量决策以及存货成本对采购数量的敏感性进行了分析和讨论.经济现值分析方法实用性强，具有科学性，有助于期货采购决策合理化和节约资金，可供原材料期货实际采购所借鉴
During the each system has been perfected , the incurred bids has also been perfected through many years practice in jilin chemical fiber company . besides some projects which should be carried on by the tender representative agency according to the legal rule , others all are carried on by the internal bidding institution . it has introduced the electronic commerce platform and established the enterprise interior electronic tender system 为了兼顾吉林化纤内部招标与招标代理机构招标,笔者提出通过在原有电子商务平台基础上,从规范招标组织机构、招标规则、招标策略及招标流程入手,将电子商务平台与传统招标手段相融合,最终实现为企业节约资金、缩短项目周期、确保项目质量的目的。
Conclusions as following have got through test study : ( 1 ) when impact compaction technology is applied to treat collapsible loess subgrade , the effect depth may be treated generally can not override 80 cm and impact compaction pass is optimum at 30 times . ( 2 ) for stratified impact compaction of subgrade , when compactness of each level reaches codeslstandards loose laying depth of 80 cm fits 40 impact compaction pass is the optimum combination of subgrade construction . when average compactness in each level reaches codeslstandards loose laying depth of 80 cm fits 30 impact compaction pass is the optimum combination o ( 3 ) the quality control method may request impact compaction pass as the main control index and at the same time the final division settlement is less than 10 % of total settlement as large area subgrade is constructed 通过试验研究主要得出如下认识：冲击压实技术处理湿陷性黄土地基时，其有效处理深度一般不超过80cm ，冲压遍数以30遍左右为宜；对路基分层冲压，在要求土体中各点压实度均达到规范要求时，路基冲压最佳组合为虚铺厚度80cm 、冲压40遍；在只要求土体平均压实度达到规范要求时，路基冲压最佳组合为虚铺厚度80cm 、冲压30遍；大面积施工时，质量控制方法可按照在以冲压遍数作为主要控制指标的同时，要求最后10遍分计沉降量小于累计沉降量10 ；在施工单位自己购置冲击压实机情况下，与传统施工相比较，冲击压实技术是一种既能节约资金又能大量缩短工期的施工方法。
The main virtues are shown as follow : 1 ) system engineer can control and use plc by familiariting this platform , need not understand communication protocol of plc ; 2 ) saving investment . we can use existing plc , not only the compatible plc ; 3 ) saving manpower . we can control plc with few people in whole control system , need not training many engineer ; 4 ) connecting conveniently plc each other 该平台的主要优点是： 1 )系统工程师可以只需要熟悉该软件就能对不同plc进行使用、控制，而无须了解各种plc的通讯协议； 2 )节约资金，可把现有的plc用于自动控制中，而不必再购买相互兼容的plc ； 3 )节约人力，只需少数几人就可对整个控制系统中的plc进行控制，而无须培训较多的技术人员； 4 )可方便地对plc进行联网，提高控制范围及控制规模。
