9 Management of Jobs with job groups and jobs

The definition which product (family) is produced is done by a job group. This defines which equipment, production dataset and materials are used and which configuration parameters (e.g. width, length of foil) are offered. The concrete products (roll of film with defined width and length) are models as jobs inside this group.

NOTE: Examples for different combinations of jobs are presented in the Annex.

Figure 2 – Job Management Overview

9.1 JobGroups

E.g. when a job is finished, then the status is changed, the last product is finished as well as the last lot. If the job is the last in the job group, the JobGroupStatusChanges event will be fired in addition. However, the client decides which EventTypes are subscribed.
