【正文】 modification of engineering quantity to increase after the project, increase the unit price bidding。 high technical requirements, mine engineering。 or petition in the absolute superiority of the circumstances, enterprises do not easily cast high mark. Especially when the enterprise contract the task is insufficient, and the rest. As to the low profit to contract projects, and 7 strengthen management, reduce cost, make full use of production capacity, reduce the idling of the labour force, raise the economic benefits of the enterprise. price was low but focus on the development of Construction enterprises are trying to break into an engineering task much area, or for the project of the followup project to consider, for the benefit of future development, often using lowcost strategy, sometimes even lower than cost price. In this preliminary engineering less loss, will be on the later stage of the project of more in full pensation. 8 外文文獻(xiàn)譯文（ 2） 2 報價策略的定量分析方法 定量分析方法是企業(yè)根據(jù)自己掌握的系統(tǒng)資料和有關(guān)信息，通過一定的數(shù)學(xué)模型計(jì)算，以便預(yù)測企業(yè)在一定報價水平上中標(biāo)的機(jī)會是多少，為企業(yè)找到最佳報價方案，為決策人員提供重要的決策依據(jù)，這種方法的比較精確客觀，能避免定性分析的主觀隨意性，得到歐美等國家的廣泛應(yīng)用，也為我國很多企業(yè)所重視，現(xiàn)介紹 2 種簡單可行方法 : 企業(yè)在投標(biāo)中要計(jì)算 2 種利潤，即直接實(shí)際利潤和預(yù)期利潤。用公式表示為幾 ~X 一 C 式中 :幾一投標(biāo)者在 該項(xiàng)工程中的直接利潤 。C 一工程的實(shí)際成本。?預(yù)期利潤雖然不能的反映企業(yè)從某工程上得的實(shí)際利潤，但由于它考慮了投標(biāo)是否獲勝的因素，更具有現(xiàn)實(shí)意義，故以預(yù)期利潤作為投標(biāo)決策的依據(jù)，預(yù)期利潤大的方案為優(yōu)。 9 外文文獻(xiàn)原文 （ 2） 2 the method of quantitative analysis of bidding strategies A quantitative analysis method is to enterprises according to their master system information and related information, through certain mathematical model, in order to predict the enterprise in a certain price level winning chance is many, for the enterprises to find the best quotation scheme, for decisionmaking provide important basis for decision making, this method is more accurate and objective, can avoid the qualitative analysis subjective and optional sex, in Europe and America and other countries of the widely used, but also for many enterprises in our country are attached, is introduced2 kinds of simple and feasible method: expected profit method Enterprises in the tender to calculate the 2profit, namely direct real profit and expected profit. Direct profit is the enterprise in project contracting directly from the actual profit. With the formula expression of several ~X C type: the first bid in the project in the direct profit。 C the actual costs of the project. Expected profit is the tenderer in various bidding scheme tender probability estimates based on the profit, use the following formula obtained E, =P ( X C ) =P ?Ip type: cadaveric probability of successful bidder, is their estimation. ?profit expectations although cannot reflect enterprise from a project on the actual profit, but it considers whether the bid winning factors, has more practical significance, so the expected profit as the bidding decision, expected profit is the optimal plan. techniques Specific techniques in business is to bid quote when considering the petitors of this factor, and that participate in the bidding petition is which of several specific units, and the petition method. 10
