Explanation of Time Categories and Time Types

Production time

The production time is the time requirement immediately related to the production of pending jobs. All times needed are productive times. We differentiate between setup time, execution time, and mis­cellaneous production time.

•Setup time

The setup time is used to set up the production plant to process a job.

•Execution time

The execution time is the time needed to produce the product.

•Miscellaneous production time

Miscellaneous production time covers all times that are neither setup nor production times but can nevertheless be assigned to a job directly. These are, for example, drying times or times required to wait for the customer.

Waiting times are regarded as "Miscellaneous production times" if they are caused by the cus­tomer.

Auxiliary time

Auxiliary time is the time required to establish and maintain the operational readiness. This time is in no way related to a job.

Examples of auxiliary times:

•Organizational issues such as waiting for paper or waiting for plates

•Technical issues such as machine maintenance or repair.

•Workplace-related auxiliary times such as rubber blanket change, start up and shut down.

Waiting times are regarded as auxiliary times if they are caused by disposition issues (waiting for paper or waiting for plates).

Down time

Down time is the time during which no production takes place although the employees are being paid.

Examples of down times:

•Pause

•Internal meeting

•Standstill times caused by lack of orders

Waiting times are regarded as down times if they are caused by a lack of orders.
