10.5 – Resource-Related Techniques
10.5.1 – Using a Resource at an Activity
A resource (employee, machine, etc.) is used at an activity to perform the activity.
Suggested Technique
1. Create the activity where the resource will be used.
2. Create the resource. (Be sure that the Object Type field in the properties dialog indicates Resource.)
3. Connect the resource to the activity.
Alternatively, you may use the GET and FREE statements in the Action logic of the activity. Connected resources will always be captured before resources specified in a GET statement. On the other hand, resource connections that free a resource occur after any Action logic for the activity.
TO DO: Create the resource and connect it to the activity as shown above.
For simple situations like the previous one, it may not be necessary to model the resource unless there are times when it is unavailable due to other activities requiring its use, since it would probably be of no interest to the modeler.

10.5.2 – Using a Resource to Move Entities
Routing an entity with the use of a resource (employee, machine, etc.).
Suggested Technique
1. Create the routing connection where the resource will be used.
2. Create the resource. (Be sure that the Object Type field in the properties dialog indicates Resource .)
3. Connect the resource to the routing connection using the line tool.
Alternatively, you may use a GET statement in the Action logic of the routing connection and a FREE statement in the Action logic of the next activity. Connected resources will always be captured before resources specified in a GET statement. On the other hand, resource connections that free a resource occur after any Action logic for the routing or activity.
Example: Patients in a waiting room are escorted to a treatment room by a nurse.
TO DO: Connect the nurse (once created as above) to the appropriate routing.

10.5.3 – Keep a Resource throughout Multiple Activities
A resource is continuously used throughout a number of activities, including the moves from one activity to another. Useful in modeling resources such as case workers.
Suggested Technique
1. Connect the resource to the activity where the resource will first be used and select Get from the Type field in the properties dialog of the connection.
2. Connect the resource to the activity where the resource will last be used and select Free from the Type field in the properties dialog of the connection
