Industrial engineering
While originally applied to manufacturing, the use of "industrial" in "industrial engineering" can be somewhat misleading, since it has grown to encompass any methodical or quantitative approach to optimizing how a process, system, or organization operates. In fact, the "Industrial" in Industrial engineering means the "industry" in its broadest sense. People have changed the term "industrial" to broader terms such as Industrial and Manufacturing Engineering, Industrial and Systems Engineering, Industrial Engineering &amp; Operations Research, Industrial Engineering &amp; Management.
