问题 单项选择题

某商品流通企业在编制年度生产经营计划时,有三个目标:(1)增加利润总额,(2)提高市场占有率;(3)增加销售额。为了实现这三个目标:拟定了四种方案,每种方案对各项目标的价值各不相同。各项目标的权数和各方案对各项目标的预计价值得分(十分制)如下表所示。用价值分析法选择比较满意的方案是()。

A.甲

B.乙

C.丙

D.丁

答案

参考答案:D

解析:

该题所列各方案的数字是各方案对各项功能优劣而估计的分数,此例采用的是十分制。评价方案的标准是综合价值系数。各方案的价值系数如下:

甲方案的价值系数V=8×0.5+4×0.2+6×0.3=6.6;

乙方案的价值系数V=6×0.5+3×0.2+8×0.3=6;

丙丁方案的价值系数V=2×0.5+7×0.2+9×0.3=5.1;

丁方案的价值系数V=5×0.5+6×0.2+10×0.3=6.7。

通过计算和比较各方案的价值系数可以看出,丁方案的价值系数(V=6.7)最大,所以丁方案是比较满意的方案。

Long ago, Bluebird’s feathers were the colour of dust. She did not like her ugly colour. She was attracted by the colour of the lake near her home. It was as blue as the sky after a storm. Bluebird wanted to be the colour of that beautiful lake very much. Flapping her wings one morning, Bluebird flew from her tree to the blue lake. Then she bathed in the water three times. After each bath, she sang, “Blue water. Still water. I went in. I am blue.” Bluebird repeated this every morning. On the third day, she came out of the lake with beautiful blue feathers.

Now Coyote was a trickster(骗子)—and hungry too. He stayed behind Bluebird’s tree for a long time every day and watched her go to the lake. He pretended(伪装) to be interested in everything she did. He wanted Bluebird for lunch, but he was afraid of the blue water. On the third morning, Coyote saw Bluebird come out of the lake with beautiful blue feathers. Impressed, he sat next to Bluebird’s tree and waited for her. When she returned, he asked, “How did you get blue feathers? I want to be blue like the mountains too.” Bluebird didn’t believe Coyote, but she taught him how to bathe three times each morning and how to sing her song. Coyote did what she said, and after three days of bathing in the lake, his white fur turned deep blue.

Convinced(确信的) that blue fur was even more beautiful than blue feathers, Coyote forgot all about being hungry. He ran as fast as he could to the top of the hill. Standing on his back legs, he raised his front legs off the ground and howled. But Coyote slipped(滑倒) and rolled down the hill. He couldn’t stop himself, and the dust and dirt covered his new blue fur. He rolled and rolled until he hit into Bluebird’s tree heavily. No matter how much he tried, foolish Coyote could not shake the dust from his fur. And so the fur of all coyotes had the dull colour of dust to this very day.
