     Mr. and Mrs. Smith had always spent their summer holidays in New Jersey in the past, staying in a small

inn at the foot of a hill. One year, however, Mr. Smith made a lot of money in his business, so they decided

to go to London and stay at a really good hotel while they went t turning around that famous city.

     They flew to London and arrived at their hotel late one evening. They expected that they would have to

go bed hungry, because in that small inn in New Jersey, no meals served after seven. They were therefore

surprised when the man who received them in the hall asked whether they would take dinner there that night.

     "Are you still serving dinner?" asked Mr. Smith.

     "Yes,certainly, sir," answered the man. "We serve it until half past nine."

     "What are the times of meals then?" asked Mr. Smith.

     "Well, sir," answered the man. "We sever breakfast from seven to half past eleven in the morning, lunch

from twelve to three in the afternoon, tea from four to five, and dinner from six to half past nine."

     "But that hardly leaves any time for us to see the sights of London!" said Mrs. Smith.

某公司拟与外商合作建厂。合作期限20年,基准收益率为10%。该公司希望从沿海城市选择出适当厂址。初步拟定在三个厂址,分别为A、B、C。

为了综合考虑影响厂址选择的定量因素、定性因素,建立衡量备选方案优势的模型如下:

Mj=αMEj+(1-α)MNj

式中Mj——第j个厂址的综合优势;

MEj——第j个厂址定量因素的优势;

MNj——第j个厂址定性因素的优势;

α——厂址定量因素优势的加权值,且0≤α≤1,本题目取定量因素α=0.57;

(1-α)——定性因素优势的加权值;

ACj——第j个厂址年总费用;

Wk——第k个定性因素的重要性权值;

Rjk——第j个厂址第A个定性因素的评分值。

根据上述模型,收集测算有关数据。各备选厂址方案成本费用见表2-1,各备选厂址定性因素对比表见表2-2,其中:评分为好的,得4分;评为中的,得3分;评为弱的,得2分。各备选厂址定性因素权值与评分见表2-3。
