First of all, the editor actually has considerable control over the review process, including the review progress, which means that the editor will know how long your paper will have to wait in the system before the review results will come out.
Secondly, in the publishing industry, it takes about 90 days on average from submission to online publishing. In other words, you need to wait about three months before the review of the paper can be completely completed. If all goes well, the paper will be accepted and published. It will take about three months.
Personal experience
From personal experience, editors are willing to contact the author. Most editors, including myself, have other jobs besides submitting and reviewing manuscripts. Take me for example. I used to be a full-time scholar in many universities, and later I became a periodical editor. The point is that there are many editing tasks and heavy tasks. An editor like me needs to deal with 80 to 100 papers every year. The author is welcome to send us an email to remind us. You will not "disturb" or "harass" the editor, please feel free to contact.
Indeed, if you still don't get any reply after submitting your paper for more than two months, it is necessary to contact the editor who is responsible for handling your paper submission.
Please remember
The whole process, from submission, review, modification to acceptance, takes about three months on average.
We have provided you with the template (note: the template was first published in the author's WeChat group, and the way to obtain the template is attached at the end of the article). Please write politely and ask if your editor can speed up the review process. Maybe you can recommend more reviewers, because the shortage of reviewers may slow down the review process. As mentioned just now, editors have great control over the review process. He or she may ask four or five colleagues to review your paper, but he or she has not received any reply.
Take me as an example, I usually invite more than four reviewers to review the papers screened by the editorial department and give their opinions (veto, major revision, minor revision and acceptance). After receiving two review opinions, if the first two review opinions are inconsistent, I will refer to the third or fourth one. This is the process of judgment.
