Modeling/Simulations Practice
1. When customers visit a supermarket, they do not expect to wait in checkout queues for too long, however the supermarket manager cannot afford to have all the checkouts open all of the time.
In an attempt to solve the problem the supermarket manager may decide to make a computer model using a spreadsheet to calculate the optimum number of checkouts that should be open at any time. N07P1
(a) Define the term computer model. (2)
Computer model is a simulation of a real life situation like a check out line a grocery store that allows variables to be changed in order to receive the most possible productivity.
(b) Describe two inputs into the model that would be needed in order to calculate the best number of checkout operators. (4)
Two different inputs that could be used could be, a key board for alternating the data also sensors which automatically collect data from the check out machines.
(c) Explain why this or any other computer model may not give accurate results. (4)
This and other computer models like it could potentially not give accurate results because there are going to be other variables that can not be accounted for. this would cause the rate of costumers to change and then the amount that the grocery store opens would not be correct. Another way that the table could not work completely is because the grocery store can account for holidays but there are other holidays and special events that they will not be able to calculate, there might be a big local game so everyone goes to the store that night or something along those lines.
2. Computer models and computer simulations are often used by businesses to test and train staff. One situation where a computer simulation is used is in the training of airline pilots. M07P1
(a) Define the term computer simulation. (2)
Computer simulation is a situation that is completely simulated- pilots are often trained using this sort of technology.
(b) Describe two input devices that would be used in a pilot training computer simulation. (4)
Two input devices that a pilot uses are the joy stick thing that they use to steer the plane and also another input device would be all of the buttons in which control the wings, wheels, air pressure, and others as well.
(c) Explain one benefit and one problem associated with training pilots on simulators instead of using real planes. (4)
One benefit to training pilots in simulations instead of real life is that they are not liable for the really expensive planes if they do "crash" while they are learning. One draw back is that it is a simulation, yes if it is good enough to train people with it must have a lot of the different variables connected into it, but there is nothing like first hand experience, and truly learning how to fly the plane and how it feels like.

- I agree with this statement but in the reading it refers to an idea of a potential new ice age, this is obvisoly incorrect and it shows that computer modeling is not always correct. This is correct because all of these different studies used computer models, The models use past knowledge and then create a hypothesis for the future based on what was entered into the computer model.
- Income tax- that is forumal based
- moon- science based
- co2 science based
- optical fiber- 30 years is a long time
- speed of a boat- conditions are always different
- The number of tons in the known reserves of an important natural resources say copper
- the average amount of the resource used per person (worldwide) per year
- the total population of the world.
