Definicja reference type (SCM-APO-MD)

Co znaczy REFERENCE TYPE (SCM-APO-MD):

Type of relationship between two activities.

The reference type defines the behavior of the successor activity in terms of start and end.

The following reference types exist:

End-start relationship: The most simple relationship between two activities. Activity 2 cannot begin before the end of activity 1. A pause between end and start is not necessary. There can be a minimum/maximum time variance between end and start. Start-start relationship: The start of one activity is dependent on the start of another activity. These two activities can start at exactly the same time, or with a minimum/maximum time variance. End-end relationship: The end of one activity is dependent on the end of another activity. The end of both activities can be at exactly the same time, or with a minimum/maximum time variance. Start-end relationship: Activity 1 can only be ended once activity 2 has started. For shiftwork, this means that the foreman (activity 1) can only end his shift once the next foreman (activity 2) has started his shift, as a handover is required. The end of both activities can be reached simultaneously or with a minimum or maximum time variance
