前一类方法保持订货量为常数，如有固定订货批量法和 (6) 等，其后者是通过确定采购或制造某产品的投资最大效益确定订货数量来降低成本的。
后一类方法先做订货计划，然后订货数量被计算确定，如有固定周期批量法和 (7) 等，其后者是一种按需订货法；还有一种 (8) ，它生成的计划订货量随着净需求的改变而改变，而订货间隔是用公式计算出来的，不是任意设定的。

     The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.

     The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being

free from colds until coming into contact again with infected people from the outside world by way of

packages and mail dropped from airplanes.

     During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet,

showed no increased tendency to catch colds.

     In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.

     At the Common Cold Research Unit in England, volunteers took part in experiments in which they put

themselves into the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in

drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

     If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by

scientists is that people tend to stay together indoors more in cold weather than at other times, and this

makes it easier for cold viruses to be passed on.

     No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as

aspirin, but all they do is to relieve the symptoms.
