For our manufacturing end customers (especially, for small and mid sized production companies) we often develop visual scheduling applications that are exactly tailored to the individual and specific production planning requirements. When specifying these requirements, we very often realize that a great deal of added value is created by linking operative production planning to the real-time events on the shop-floor. In other words: by equipping dynamic planning with dynamic updating, such as a GPS for cars that informs us about the distance to move and the expected arrival time. We call this the synchronous scheduling Gantt chart.
This blog post gives you an idea about the principle of a synchronous Gantt diagram that could be compared to a GPS for production planning.
