摘要/Abstract

摘要： 目前常用的各种厂址选择方法或者不能对备选方案的影响因子进行定量分析，或者只能对备选方案的部分影响因子进行定量分析。为解决这一问题，提出了一种能对备选方案的所有影响因子进行全面定量分析的厂址选择新方法——影响因子量化加权法。其具体做法是先针对建设投资和运营费等定量影响因子计算出定量影响因子价值分，再将自然、经济、社会等方面的定性影响因子赋予条件概率和比重，并由条件概率和比重乘积之和得出定性影响因子价值分，最后将定量影响因子价值分和定性影响因子价值分分别乘以各自的权重后相加，得出综合影响因子价值分，综合影响因子价值分最高者即为最优方案。运用该方法对中国某企业拟在蒙古国建设的H铁矿选矿厂进行厂址和运输方案优选，结果表明，2个备选厂址及6种备选运输方案中，备选厂址一所对应的运输方案1~3的综合影响因子价值分明显高于备选厂址二所对应的运输方案4~6的综合影响因子价值分，而运输方案3的综合影响因子价值分在6种备选运输方案中最高，由此直观明了地得出了厂址一配运输方案3为最佳方案的结论。

Abstract: The popular site selection methods at current cannot be used to make quantitative analysis on the influence factors from the alternatives or partly.In order to solve this problem，a new method,influence factor quantification and weighting method is put forward，which can fully or quantitatively analyze the alternatives of all influence factors.The specific approaches are as follows:firstly，the value of influence factors is calculated out according to quantitative factors of construction investment and operating costs.Then，the probability and weighting for the natural，economic and social aspects of conditional influence factors are given，and the qualitative value of the influence factors is obtained by multiplying the probability with the weighting.Finally，the value of comprehensive influence factors is gained by sum of both of multiplying the quantitative influence factors and qualitative influence factors with their weighting separately.The method with the highest influence factors value will be optimum.The optimum method is used to optimize the site selection and transportation scheme of H iron dressing plant in Mongolia built by a Chinese company.The results indicates that among the two alternative sites and six alternative transportation schemes，value points of comprehensive influences factors corresponding to transportation scheme 1~3 for site 1 is obviously higher than that of transportation scheme 4~6 for site 2，meanwhile the value points of comprehensive influence factors of transportation scheme 3 is the highest among the six transportation alternatives.The conclusion is that site 1 matching with transportation scheme 3 is the best choice.
