The order of cooking is for chefs 1 and 2 to cook a dish for each of A and B, then to A and C, and finally to B and C, because this can shorten the waiting time of the guests and can serve them as quickly as possible. The speed is so fast that all the guests can eat it.

If two chefs take five minutes to cook each dish, then the minimum waiting time for the guests is 15 minutes. The order of cooking is that chefs 1 and 2 cook a dish for each of A and B, and then Give it to A, C, and finally to B and C, because this can shorten the waiting time of the guests and allow them to eat as quickly as possible.

Analysis:

According to the meaning of the question, we set it as chef: 1.2, guest: A. B． C. Assuming each dish takes 5 minutes, 1.2 is given to A. B cooks a dish for each person and gives it to A. C, and finally to B. C. One session takes 15 minutes, from which the best method can be derived.

Extended information:

The basic idea of ??the overall planning method is to make overall arrangements and make reasonable arrangements. In the article "Overall Planning Method", Professor Hua Luogeng uses a very simple example of making tea to illustrate.

For example: When I get up in the morning, I want to make a pot of tea. The situation at that time was: there was no boiling water, and the kettle, teapot, and teacups needed to be washed. The fire had risen and the tea leaves were available. What should I do?

Method 1: Wash the kettle, fill it with water, and put it on the fire; wait for the water During the boiling time, wash the teapot and teacups, and put the tea leaves in; wait for the water to boil, and make tea to drink.

Method 2: Wash the kettle, teapot and teacups, put tea leaves in them; fill them with water and put them on the fire; wait for the water to boil and make tea.

Method three: wash the kettle, fill it with water, and put it on the fire; wait for the water to boil, wash the teapot and teacups, put the tea leaves, and make tea to drink.

Obviously, the first method is more time-saving and more in line with the idea of ??overall planning.

The basic idea of ??the overall planning method is: first, focus on the overall progress of the tasks that need to be managed, take the duration required for each task in the task as the time factor, and make an overall plan according to the order and interrelationship of the tasks. , to reflect the overall picture of the task and realize the modeling of the management process.

Then perform time parameter calculations to find out the key tasks and key routes in the plan, and make reasonable arrangements for the people, finances, and materials required for each task by improving the network plan, thereby obtaining a reasonable plan and put it into practice.

In addition, various evaluation indicators can also be quantitatively analyzed, and effective supervision and control can be carried out during the implementation of the plan to ensure that tasks are completed with high quality and quantity.
