简述流程式生产与加工装配式生产的不同特点

答案

参考答案:

解析:(1)对流程式生产来说,生产设施地理位置集中,生产过程自动化程度高,原材料品种较少,物流系统相对简单。 (2)在加工装配式生产过程中,产品是由离散的零部件装配而成的,这种特点导致生产的生产设施地理位置分散,零件加工和产品装配可以在不同地区甚至不同国家进行,由于零件种类繁多,加工工艺多样化,又涉及多种多样的加工单位、工人和设备,零部件的流动是非连续的且成网络状,导致生产过程中的协作关系十分复杂,凸显各加工单位间物流配送的重要性。

     "Mum, what does it mean when someone tells you that they have a skeleton (骨骼) in the closet (衣橱)?" Jessica asked. "A skeleton in the closet?" her mother paused thoughtfully. "Well, it's something that

you would rather not have anyone else know about. For example, if in the past, someone in Dad's family

had been arrested for stealing a horse, it would be 'a skeleton in his family's closet'. He really wouldn't

want any neighbor to know about it. "

     "Why pick on my family?" Jessica's father said with anger. "Your family history isn't so good, you

know. Wasn't your great-great-grandfather a prisoner who was transported to Australia for his crimes? " "Yes, but people these days say that you are not a real Australian unless your ancestors arrived as

prisoners." "Gosh, sorry I asked. I think I understand now," Jessica cut in before things grew worse.

     After dinner, the house was very quiet. Jessica's parents were still angry each other. Her mother was

ironing clothes and every now and then she glared at her husband, who hid behind newspaper pretending

to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica's

closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark

depths and a bundle of white bones fell to the floor. Jessica's mother sank into a faint (晕倒), waking

only when Jessica's put a cold, wet cloth on her forehead. She looked up to see the worried faces of her

husband and daughter.

     "What happened? Where am I?" she asked. "You just destroyed the school's skeleton, Mum,"

explained Jessica. "I brought it home to help me with my health project. I meant to tell you, but it seemed

that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad. " Jessica

looked in amazement as her parents began to laugh madly. "They're both crazy," she thought.
