Question 128 - CPIM-Part-2 discussion

A push system is a production system that operates based on planned or forecasted demand, rather than actual or current demand. In a push system, work orders or tasks are released to the work centers according to a predetermined schedule, regardless of the availability of capacity or resources at the work centers.This means that work centers may receive work even if they are already overloaded or have no idle time, which can result in long lead times, high inventory levels, and poor customer service1.

The other options are more likely to occur when using a pull system, which is a production system that operates based on actual or current demand, rather than planned or forecasted demand. In a pull system, work orders or tasks are released to the work centers only when there is a need or a request from the downstream work centers or customers.This means that work centers are scheduled using finite capacity planning, which is a method of allocating capacity and resources based on the actual availability and constraints of the work centers2.Work centers also operate using decentralized control, which means that each work center has the autonomy and authority to make decisions based on the local conditions and signals from the environment3.Work centers also signal previous work centers when they are ready for more work, which is a way of synchronizing the flow of materials and information along the production process4.
