How difficult is it to graduate with a doctorate in logistics?

It's hard. It is difficult to graduate with a doctorate in logistics for the following reasons:

1. In addition to writing graduation thesis, Dr. Logistics also requires at least two small papers to be searched by three international indexes: SCI, SSCI and EI. This is the most difficult stage for doctoral students.

2. The release of the mentor is also a very insurmountable mountain. To complete the tutor's topic, it depends on the tutor's arrangement and even the tutor's mood.
