OOPUS - A production planning information system to assure high delivery reliability under short-term demand changes and production disturbances

Batch-sizing and scheduling is the central decision problem in the area of production planning. A special challenge in this context is to handle the big amount of data in an adequate time interval. To aggregate and to illustrate this data clearly, appropriate techniques are required. This paper presents a new approach to integrate a Production Planning Table visualized by a Gantt chart and a cumulative quantity table for maximum information transparency in production planning. The discussed solution is realized in OOPUS, an object-oriented tool for planning and control, which became the leading production planning system in two motor assembly plants of an international automobile manufacturer.
