Great introductory text for a non-IE. Very broad, covers most of the range of the IE topic. I used it as a study aid when studying for the PE exam; I passed, and I credit much of that to this book.
Good: Covers lots of stuff that was on the exam, including:
-Industrial processes (metal cutting, Taylor tool life eqn)
-Facility layout
-Facility location (traveling salesman, milk run algorithms)
-Operations planning (forecasting demand, EOQ, exponential forecasting)
-Project management (PERT, crashing, forward/backward pass)
-Good introduction to stats and probs in the appendix
Not-so-good:
-Lots of wasted space on management theory (get a business text instead)
-Computer stuff is out-of-date
It does not go into substantial detail, so it is (as titled) an introductory text. Still, I highly recommend it to the non-IE.
