Modelling Applications and Types of Processing

     This topics may be rare to encounter in our daily life. However, whether we realize it or not, this type of application is often used by us. For example, the traffic light simulation, tuck shop model,flight simulator for pilots or even weather forecasts. There are 3 types of processing. Below are the detailed information about modelling applications and types of processing.

Modelling Applications

     Basically, modelling application is an application to study the surroundings. This application has some advantages like low-cost and safer. As a drawback, modelling application is never exactly the same like what happens in real life and as a program, there might also be some errors. Here are some examples of modelling applications.

Traffic Light Simulation

     Traffic Light Simulation is the replica of the real condition on the road which is transferred or captured in our computer. In particular, three threads operate concurrently to represent are the cars, the traffic flow volume and the traffic lights. The data are collected by watching the traffic for a long period of time. Then, the data are entered to the computer so the traffic observer can just observe the traffic from the computer. 

The data that need to be collected are:

- The number of vehicles passing the on the road

- Is there any vehicle amount changes during holidays

- How long it takes the slowest vehicle to pass through the junction

- The movement of the vehicles

- etc

     However, The problem with microscopic simulators for traffic light networks is that the outcomes are largely non-linear and require a large number of replications to get accurate results, which can drive up the cost of doing the simulation.

Sensors are also present to help gathering the data.

Tuck Shop Model

     Tuck shop model is usually used for business or in the school supply shop. This model can save all the data about the purchase happening. It helps users to input the data easier as they just need to type in the formulas and the results will automatically appear. Tuck Shop can also tell about the profit or loss.

Flight Simulator

     Flight simulator is definitely used by training pilots. This kind of simulator helps pilot a lot before they will experience their "real life". This mimics the skills that a pilot needs. After a pilot is qualified in this flight simulator, they can now fly an airplane officially. Flight simulator can also be used for engineering simulation. It comes in a low-priced compared to a real flight where you are ought to buy a plane with a highly-cost parts of planes.

Weather Forecasts

     Weather forecast is a very useful system used by us to see the weather for today. This forecast can predicts today's weather, earthquake or even tsunamis which definitely helps us a lot. It may not be accurate because weather is so complex and it can changes every second.

Types of Processing

There are three basic types of processing:

- Batch processing

- Real-time processing

- Real-time process control

Batch Processing

     Batch processing is a process where jobs are collected into a data and loaded in a computer system. One advantage is that jobs can be processed when the computer is less busy. A common example of batch processing is in the use of credit cards. We may use several credit cards but the bill is mixed into one for each month. Another example is school attendance and bank cheque processing.

Real-time processing

     Real-time processing is a process which is used in theaters,flight bookings or when paying Automatic Teller Machine (ATM). This process is an online processing. One advantage of this process is a very fast response. However, this system or process must always be online due to the different period of time the users will check the system and is very expensive.

Real-time process control

     Real-time process control is a system where physical quantities are continually monitored and the input is processed sufficiently quickly to influence the input source. This kind of system has an accurate data.
