  • Push System: In a push system, releases are scheduled.  So, throughput is determined by a exogenously set release rate (given by the Master Production Schedule).  Since the releases are linked to orders (or forecasts), a push system is controlled by upstream information and is inherently make-to-order. In terms of our nomenclature, open lines are push systems because they have no endogenous restriction on releases to the line.
  • Pull System: In a pull system, releases are authorized.  That is, there is an endogenous signal based on system status that determines whether a release is allowed or not.   In particular, the system status that triggers releases is based on stock voids, which means that a pull system is controlled by downstream information and is inherently make-to-stock.  In our nomenclature, closed lines are pull systems, because buffer spaces act as stock voids to trigger releases

Push system is based on pre planning, that means you will plan in advance and purchase goods according to fixed quantity or value.

While pull system is according to the actual demand. Supply chains are working on push based system to minimize bull whip effect.

Just browse the net, you may get the exact definitions and more explanation.

On the practical side for effective SCM, both are needed. It depend upon the user, when & where to apply them.
