ACTIVITY Statement

The CPM Procedure

ACTIVITY Statement

ACTIVITY variable;
ACT variable;

The ACTIVITY statement is required when data are input in an AON format; this statement identifies the variable that contains the names of the nodes in the network. The activity associated with each node has a duration equal to the value of the DURATION variable. The ACTIVITY variable can be character or numeric because it is treated symbolically. Each node in the network must be uniquely defined.

The ACTIVITY statement is also supported in the Activity-on-Arc format. The ACTIVITY variable is used to uniquely identify the activity specified between two nodes of the network. In the AOA format, if the ACTIVITY statement is not specified, each observation in the Activity Data Set is treated as a new activity.
