Computer models and simulations

This document discusses how computers can be used to organize and analyze various types of data. It provides examples of using databases and spreadsheets to track membership information for clubs, sales data for a business, student academic performance and surveys. Simulations are also discussed as a way to model real-world systems without building physical models, allowing testing of designs for things like bridges and airplanes.

 Even if you don't work for a huge business, It can be
useful to use computers to keep track of data.
Data that is stored on a computer (as opposed to
data written on paper) can be easily:
organised / sorted in different ways
 displayed / printed in a variety of styles and layouts
 searched for specific things
 updated - adding / changing / deleting items
 backed-up - a copy can be made with just a few
clicks
 stored / moved - a memory stick is much smaller
than a cupboard full of paper!
 Clubs / societies need to keep track of their members. A membership
database allows the club / society to easily contact members, check that
they have paid any fees, etc.
A typical computerised membership database might store:
Membership number
 Name
 Address
 Phone number
 Fees to charge
 Have fees been paid (Y/N)
 Etc.
 If a letter needs to be sent to every member of the club / society, the
names and addresses of the members can be taken from the membership
database and automatically placed onto a letter. This is called a mail-
merge.
A mail-merge is a very easy way to automatically create lots of letters
that seem to be personally written for each person, but in fact are all the
same letter, just with the name and address changed.
 Many groups / organisations undertake surveys to try to
discover what people like / want / think.
Surveys can be performed using paper questionnaires, and
then the results entered into the computer by:
Typing data in
 Scanning the paper forms, using OMR technology
 Alternatively, results can be entered into the computer
directly, using an on-screen form (e.g. if using a tablet PC)
The survey results are best stored on a computer so that
they can easily be analysed. Survey results on a computer
allow:
Data to be quickly and easily queried (filtered)
 Charts to be easily created
 Summary reports to be created
 A simulation is the creation of a model of a
real system in order to study the behaviour
of the system.
 it is important how system behaves and
possible predictions
 Examples: spreadsheet representations,
flight simulations,trafic light simulation.
 There are several reasons that computer models
are used…
To test a system without having to create the
system for real (Building real-life systems can be
expensive, and take a long time)
 To predict what might happen to a system in the
future (An accurate model allows us to go
forward in virtual time to see what the system
will be doing in the future)
 To train people to use a system without putting
them at risk (Learning to fly an airplane is very
difficult and mistake will be made. In a real
plane mistakes could be fatal!)
 To investigate a system in great detail (A model
of a system can be zoomed in/out or rotated.
Time can be stopped, rewound, etc.)

  • 7.  they are less expensive.  It is safer to run simulation.(chemical process)  Various scenarios can be tested in advance.  Sometimes it is impossible to try out some experiments in real life. (outer space, under the sea, in nuclear reactors, crash testing cars, etc.)  it is often faster to model a situation. ( climate changes, population growth)
  • 8.  They are only good as the data used and the mathematical alghoritms representing the real life situations.  žthey are very expensive to set up and often require specialist software to be written.  they frequently require very fast processor/computer system.
  • 9.  A computer model of a car can be used to test how safe the design of the car is in a crash. The virtual car can be crashed over and over again, the effects investigated and the design easily changed until it is as safe as possible. This is much quicker and cheaper than building and crashing real cars!
  • 10.  A computer model of a weather system can be used to predict storms. The wind patterns, temperatures, etc. for the whole planet are simulated using very powerful computers. If the computer model is accurate (it is very difficult to make an accurate model since our planet is rather big) then weather forecasters can use it to ‘fast- forward’ into the future to see a prediction of what the weather will be tomorrow, next week, next month. (Since weather is so complex, and the models are not (yet) accurate enough, often the weather forecast is wrong!)
  • 11.  A computer model of a bridge can be used to test the design.  Bridges have to be able to survive extreme weather conditions. It is obvious not practical to build a real bridge and then wait to see if it falls down in a storm.  Instead, a computer model of the bridge is created and tested in virtual storms.  If the model breaks, it can be quickly and cheaply re-designed and re-tested. If it doesn’t break, the real bridge can be built, confident that it will survive real storms.  Bridges can also be tested to see if they can cope with heavy traffic. The virtual bridge can be loaded with a traffic jam of virtual trucks to check that it won’t collapse.  A similar system is used by building designers, especially for very large or tall buildings, such as skyscrapers.
  • 12.  Trainee pilots have many hours of lessons in flight simulators before being allowed to fly a real airplane.  Flight simulators behave almost exactly like real airplanes since they are controlled by a computer with a very accurate and realistic model of the airplane.  The main difference is that the simulator can’t actually crash!  Pilots can make mistakes without putting anyone’s life at risk.  Flight simulators can provide a pilot with any number of highly realistic flying situations: storms, engine failures, low cloud hiding the runway, etc.  The experience that pilots gain whilst using the simulator means that when they eventually start flying real airplanes, they already have many of the required skills.
  • 13.  It's important, when selling things, and dealing with cash, to keep track of the numbers involved. A computer spreadsheet is an good way to record which items you have sold, and also to perform calculations on the data (calculate totals, averages, etc.).

  • 14.  A school would typically keep data on student academic performance in a computerised database. This would allow the school to easily track how students were doing as the year progressed, as well as making the creation of printed reports very easy (compared to hand writing every report) A typical school report database might contain: Student ID  Name  Tutor group  Grades for Term 1  Attendance for Term 1  Comments by teachers for Term 1  Grades for Term 2  Etc.  Most database programs allow data to be presented in attractively design reports that can include headers and footers, school logos, etc.
