 You can also use Kanban to schedule the assemblies in another workshop or plant, but it is usually not done when these assemblies are produced on large machines because with MRP the demand of several days can be comprised in bigger lot sizes of production orders of similar type in such a way that the workshops own scheduling system (MES) is then able to use the available machine-capacity better by bringing the production orders into an optimal sequence using suitable algorithms.This is usually the case when the machines are expensive, their number is relatively small and they have big output-capacities and setup time is expensive.Implementing Kanban in such a case would require to use a bigger number of smaller\cheaper machines, dedicated to certain production lines, in order to react more flexibly to the demand.
