TY - JOUR AB - Demonstrates the importance of planning systems and indicates which planning systems are suitable for which purpose. Focuses on batch production in short series and reports on results from three cases, where the planning function has been adapted to the existing production organization in the companies studied; it is shown which planning systems are used for different needs. The frame of reference builds on earlier theories concerning different types of planning systems and their advantages and disadvantages. It is clear from this frame of reference that the primary function of a planning system is to support and execute the production of products in such a way that the best overall performance is achieved. The variables that have the greatest influence on the choice of a planning system are type of organization, layout/material flow, set‐up times and frequency of deliveries. Shows that the choice of which system to use must be made according to the result of the analysis of variables and their interaction. Thus there is a need for more than one planning system within companies in a particular industry.
