Input/Output control
Is an effective technique for controlling queues, work in process and manufacturing lead time
Planning the acceptable input and output performance ranges per time period in each work center
Measuring and reporting actual inputs and outputs (feedback)

Inadequate input
Jurusan Teknik Industri, Universitas Andalas
*
Principles of input/output control
The planned output should be realistic and should represent labor and equipment capacity
A planned or actual input greater that the realistic output will increase WIP, hinder production, and increase manufacturing lead time.

Gateway work center control
Management of the release of orders controls the input, queues and WIP at gateway work centers
Downstream work center control
The input and queues at downstream work centers are controlled by dispatching at upstream work centers in the process flow
