You can research service operations processes by combining the process (for example, "inventory management") with the company or industry name (for example, Marriott or "hospitality industry"). Here's a list of some service operation topics you can use in your search:
"quality of service"
"supply and demand"
Do use the quotation marks. This will tell the database that you are searching for a phrase, not two separate words wherever they appear.
If these don't work for you, try synonyms or brainstorm other phrases then combined with your company or industry name.
You can make your search specific to certain trade journals. Here are some titles to try:
Industrial and Corporate Change
International Journal of Services and Operations
Journal of Operations Management
Journal of Sustainable Tourism
Journal of the Operational Research Society
Journal of Travel & Tourism Marketing
Journal of Travel Research
Logistics Management and Distribution Report
Manufacturing and Service Operations Management
Production and Operations Management
