"The paper discusses the main results achieved by SPbETU "LETI" and "Oceanpribor" (Russian Federation, Saint Petersburg) during the performance of complex projects since 2010 onwards."
The intended meaning of the word in bold is "consisting of several smaller projects" and also "involving different fields of knowledge". Have I used "complex" correctly here?
I was also thinking about "comprehensive" or "integrated" instead.
Integrated or perhaps consolidated projects works better for me. "Complex" doesn't express the idea that multiple sub-projects are gathered under one umbrella.
