( 3 ) optimization design principle of long - short - pile composite foundation is put forward , base on which replacement ratio and pile length is taken as design variable , bearing capacity , settlement , stratum strength and other demands acted as constraint function , pile cost taken as objective function , so the optimization design model of long - short - pile composite foundation is built ( 3 )提出了长短桩复合地基优化设计原理,在此基础上将置换率和桩长作为设计变量,承载力、沉降、下卧层强度等要求作为约束函数,总制桩费用作为目标函数,建立出长短桩复合地基优化设计数学模型。
Cost takes up an important station in company management , currently our principal task is that we should use foreign experience of advanced cost management for reference with combining actualities of our country , in order to improve the level of cost management of our enterprises , and shorten the difference between our country and advanced country in the field of cost management 成本管理在企业经营管理中起着致关重要的作用。如何从我国的成本管理的实际出发，借鉴国外先进的成本管理经验，提高我国广大企业的成本管理水平，缩短我国与国外先进水平的差距，是我国企业成本管理工作迫切需要解决的问题。
Company possesses the present domestic most advanced st - eel personal computer of h model to control full automat - ic production line , ensures very efficiently that reas - onable cost takes off efficient production running , be - comes to possess manufacturer home of steel structure of profession advanced technology and equipment 公司拥有目前国内最先进的h型钢微机控制全自动化生产线，很有效地保障合理成本下高效率生产运作，成为拥有行业尖端技术和设备的钢结构生产厂家。
The theories foundation of activity - based costing , is to think that the production line should describe for : the production causes activity take place , the product consumes to used to the industry , the function consumes with the resources , thus causing cost take place . this with traditional manufacturing costing the product consume with the cost of principle is different . thus , the activity - based costing checked to track the process of the product formation and the cost backlog with the activity - based costing , carry on make track for to the cost formation to trace to origins originally , set out from here , activity - base method makes research of cost gone deep into more , the cost information is more detailed and turn and even have and can control it 本论文研究的目的是探讨作业成本法在一汽铸造一厂应用的可能性,运用作业成本法的研究方法对一汽铸造一厂的产品成本进行分析,对比传统成本法和作业成本法下的成本,对两种成本的差异进行分析,产生差异的原因。通过建立作业成本库、选择成本动因,将成本分配到相应的作业成本库,分别将传统成本法和作业成本法下的成本计算到每种铸件,再进行成本对比,重点分析差异较大的产品的成本构成,在此基础上,对企业生产作业流程的重新评价,对产品的成本构成有更全面的了解,对企业管理层提出了解决成本信息失真,改变产品定价策略,降低生产成本和改善企业内部管理的建议。
