Performance of a multistage hybrid push/pull production control system

The generic structure of production control systems for multistage manufacturing processes is modelled and a hybrid push/pull production ordering rule operated periodically is introduced at each of the stages. This combines the benefits both of push- and pull-type control concepts. The transmission of demand information between the stages plays an important role in a multistage production control system. Using the structure of multistage processes, it has been clear that the proposed multistage production control system has a nested structure of a single-stage production control system. Assuming a specific demand and forecasting model, the variances of inventory level and production level at each of the multiple-stages are investigated to provide insights into achieving ‘just-in-time’ deliveries in multistage manufacturing environments.
