ABSTRACT
The data and control flows for logistics purposes were first organized on a systematic basis in the fields of mechanical and apparatus engineering and in the automobile and aircraft industries. The MRP II concept, which has been supported by logistics software for nearly 40 years, originated in these industries. With MRP II and logistics software, a de facto standard emerged, consisting in common terminology, use of similar representations of the logistics objects, and similar implementations of the principal planning & control methods. However, for repetitive manufacturing as well as for one-of-a-kind production, the MRP II concept has already required extensions through new terminology, new representations of the logistics objects, and additional methods. The same is now taking place for process industries.
