Use all available data (there is weather information available). Notealso that you have data for several days which you can use for training and testing.
Then, add 4 columns for the delay. These delay are:
Then work on this file.
Follow the CRISP-DM framework
3. Data Preparation
Depend on the model that you use, how it deals with messing data, such as replace them with the mean values or find out what values should be, or anything you comfortable with, and provide a short description for that.
Add column for weather to the file history that we have. You can find weather data in the data files.
4. Modeling
They could be 3 different trees, and describe each model. For example, put the tree or part of it then explain everything "what does it mean? What it tell the airport? What does it mean for them? And what can they do?
Which of these models work better?
5. Evaluation
6. Deployment
Complete replication: It implies maintaining of a whole copy of the database at every site. Thus, the reliability & availability and performance for query response are maximized.
