A hybrid push/pull control algorithm for multistage, multi-line production systems

In this research, a hybrid push/pull production control algorithm is developed and tested for use in multi-stage, multi-line, assembly-type repetitive manufacturing environment. The algorithm is primarily based on a just-in-time (JIT) approach, but uses dependent demand aspects of manufacturing resources planning (MRP II) to manage the intermediate inventories. A simulation model is then developed to test the algorithm on general system configurations, on the bases of output, lead time and WIP. The simulation results show the algorithm to be effective in minimizing WIP while sustaining output capacity, with relatively little sacrifice in total lead times from the best observed values.
