Q1Answer

The model world is a demonstration of the real world scene by making and assembling man-made models containing very similar attributes and various aspects of the real world. Created a model world to understand all aspects of the real world. Today, almost all departments in the organization have used this technology, such as manufacturing, transportation, service, etc.

(A) Examples of the model world.

I will take the modeling of the manufacturing department as an example. We must have seen the mobile security testing process. This process is used to acquire knowledge about the safety of the durability standard of the mobile phone. It can be said that a company has launched a new mobile phone and it will enter the market soon. Before arriving at the store, a safety test is required. The companys team conducted this test, and if the phone receives a 5-star rating from the test, it will be considered the phone with the highest patience. By creating a modeling world, it provides convenience for people's actual needs in reality and brings people a more comfortable life.

(b) With respect to the below diagram and based on your example in part (a), identify at

least five points where the modelling process can go wrong and briefly explain them.
