Operations Research: Beyond elementary lessons

Different viewpoints on the field of Operations Research are put forward to ask from the reader a few minutes to think about. An outsider looks at Operational Research OR in Beligum. The academia-industry relationship is put into question. A comparison with the Japanese colleagues is made. Operational Research OR can be difficult or can be easy: does complexity give the answer? Or does the paper remain optimistic in Operational Research OR solving all complex problems. It takes a book at the fifties, the forties and even a glimpse of the previous century and before.
