The guideline describes the problems and procedures involved in upgrading and expanding existing materials-handling installations and logistical systems without causing any interruption to operations. Planning takes on a special importance here. One of its most important parts is an analysis of the actual state of affairs and the identification of logistical bottlenecks (weak-point analysis). This means that the existing system has to be analyzed very carefully and precisely with regard to the state of individual functions and interfaces so as to allow the replanning to be built onto this and the measures necessary for problem-free implementation defined.
