Graduation Project about Shipping Carriers Preferences on Port Selection: A Literature Review

You have 9 weeks to do it. You don't have to make it Perfect. You should build your research from this Four  Factors/Criteria:
1- Ship specification.
2- Operating costs.
3- Level of traffic at Port.
4- The value-added benefits offered to ship-owner/carriers.
The information Should be Scientific.

You will have the template file to make organizing the Project easier & faster.
You will have the Graduation Project layout picture so you know how to do & organize the project efficiently.

Why I choose These 4 instead of others factors? Require an Answer.
Why Only Four Factors? Because of the limited time is given to me.

Thanks.
