Economic studies on the scale economies may dates back to rather early time , while most of the existing literature on this regard attached too much concentration to the impacts of technology on the output size of production activity , it should be pointed out that technology constitutes only one of the factors that may affect the scale economies , besides which there are other factors such as the market environment and the social economic institutions etc . , which also affect the occurrence and fulfillment of the scale economies 对规模经济问题的研究早已有之，现有研究大部分集中于技术对生产规模的影响作用。但是技术仅仅是其中的一个因素，其它的重要因素还有市场环境、社会经济制度等，它们同样也在制约着规模经济的产生和实现，忽略这些因素的作用不利于对规模经济问题的全面和客观的认识与理解。
How to treat with the results of feasibility research reports , how the marketing to be changing , what being the key point of influencing the benefit and how about the income from investments are regardful of enterprise . the defectiveness of an enterprise can be uncovered by appraising the execution of investment , the analyzing of marketing information and the benefit of managing the project being brought into production . on the base of this , what should be advocated and what is the emphasis in investment decision can be submitted , meanwhile , the basis of analyzing the reasonableness of production scale and investment scale can be found 此项目投资效益的虚实?均是企业当前关心的问题。通过对项目的投资执行情况、市场信息分析及对企业项目投产后技术和经营效益的经济分析，可以发现存在的各种问题，从而为今后在投资决策时应该提倡什么，侧重什么，为分析生产规模的合理性以及所需投资规模提供现实依据。
Furthermore , along with the larger enterprise scale and the deeper multi - industry , enterprise payoff that accumulates by them cannot fulfill the requirement of enterprise development any longer . so whether enterprise can obtain funds from outside has become the key " bottleneck " 随着企业生产规模的不断扩大和多元化经营的不断深化，单单依靠企业自身的盈利积累已经远远不能满足企业大规模发展的需要，因此，能否获得对外融资就成为许多企业发展过程中的关键因素。
By applying profit and loss equilibrium method , and marginal analysis , taking each of the four class break - pieces in oil - field as the unit , and basing on the prices of the different oil qualities and the developing costs of only once , two times and three times , we determine the optimal yields of each break - pieces in liaohe oil - field 本论文采用盈亏平衡分析法和边际分析法等。以油田(四级断块)为单元，根据不同油品的价格和不同开采方式下的开采成本，确定辽河油田各断块的经济产量，达到优化产量结构，合理确定生产规模的目的。
With the scale of social production extends and the production horizontal exalts , the electricity control technique and the hydraulic technique all develop very quickly . electricity control technique developed from the relay system to the direct digit control ( ddc ) system the disperse control system ( dcs ) to the fieldbus control system ( fcs ) . the modem hydraulic control technique have developed to a complete automation which include of transmit control testing computer technique , and gradually turn to the digit control and full - automatic control 随着社会生产规模的扩大、生产水平的提高，电气控制技术和液压技术都在非常迅速的发展。电气控制从继电器控制系统发展到直接数字控制( ddc )系统、集散控制系统( dcs )到目前的现场总线控制系统( fcs ) 。现代的液压传动及控制技术已发展成一门集传动、控制、检测、计算机一体化的完整的自动化技术，并逐步趋向数字控制和全自动化。
In the new environments of china ' s entry into wto , on one hand , as all enterprises are facing different competitive environments and the competition becomes more severe , it objectively requires all enterprises to shorten market response time and make themselves to manufacture according to po ; on the other hand , along with the innovation of new technologies of changan auto and the speedup of new products development , the increase of production scale , the company has the internal demand to establish advanced computer system to enhance the production management level and the site cannibalization & control capabilities , to convert itself to coordinated production and provide flexible technological guarantee for the mixed vehicle production line in the aspects of materiel coordination & product line management , when it builds new product line or rebuilds old product line 在加入wto的新形势下，一方面由于企业所面临的竞争环境发生变化和程度进一步加剧，在客观上要求企业缩短市场反映时间，尽量实现按定单组织生产；另一方面随着长安汽车技术创新和开发新产品的加快，其生产规模的进一步扩大，在公司内部存在要求在建设新生产线或者改造旧生产线时，建立先进的计算机系统，提高生产线的生产管理水平，提高车间的现场调度和控制能力，向协同生产转变，为多品种的汽车混线生产在物料投放与生产线管理上提供柔性的技术保证。
With continuous spread of industry - mine enterprise production scale , there are short of transportation dispatching capability for these old subsystems of steel yard provided for themselves being outdated technology and not integrated , so the problem is more and more becoming the holdback of industry - mine enterprise development 随着工矿企业生产规模的不断扩大，由于企业自备铁路编组站原有的各个作业子系统技术落后且各自独立，从而存在运输调度能力的不足，使之成为工矿企业发展的障碍。
With the development of computer information technology , increasingly expanding of modern enterprise production scale and more and more fierce market competition , new requirements of enterprise logistics by market are emerging , and automated high - rise warehouses gains more attention and have been used widely , srm is the most important conveying and lifting equipment in automated high - rise warehouse 摘要随著计算机信息技术的发展，现代企业生产规模的不断扩大和竞争的日益加剧，市场对企业物流系统提出了新的要求，自动化立体仓库越来越受到关注并得到广泛应用。
Servo - control technology is one of the most important part of mechtronics . which is widely used on the automatic equipments . such as cnc and industrial robot . as the scale of production becomes larger and larger . the demand and requirements becomes higher and higher . ac servo system has advantage over dc servo system . so study on improving the ac servo system behavior has important sense 随着现代化生产规模的不断扩大，各个行业对电伺服系统的需求愈益增大，并对其性能提出了更高的要求。由于交流伺服系统具有直流系统不可比拟的优越性，因此，研究并制造高性能、高可靠性的交流伺服控制系统有着十分重要的现实意义。
