Use

Captures a resource or combination of resources as each resource becomes available. Once the resource has been captured it is used for the specified amount of time, and then freed when the specified duration is over. If the entity already possesses one of the specified resources from a previous GET or MOVE WITH statement, the entity will still try to capture an additional unit of that resource.

Components

(Quantity) The number of resources to get. Process Simulator ignores a value of zero and values less than zero return an error. Process Simulator evaluates and truncates this numeric expression every time it encounters the USE statement. If no quantity is entered, one unit of the resource will be used.
If you define a quantity and enter a resource group in the Resource field, the quantity entered here will be multiplied by the quantity defined in the resource group. For example, if you have a resource group that has 1 Doctor and 2 Nurses, and you choose a quantity of 2 for the GET statement, 2 Doctors or 4 Nurses will be captured.
Resource The name of a previously defined resource to USE.
(Priority) When multiple entities request a resource, Process Simulator fills the requests in order of priority. This expression is a number between 0 and 10, with an interrupt option.
Time The length of time, in the time units defined in the next field, that the entity will tie up the resource. Process Simulator evaluates this expression whenever it encounters the statement.
Time Units The unit of time in seconds, minutes, hours, days, or weeks that is applied to the Time field.
(Operator) Allows you to list additional or alternate resources that the entity will capture and use.

Please note: When using the USE or GET statement to capture a resource in activity logic, you do not need to define a resource in the Activity Properties dialog. The resource defined for use in the Activity Properties dialog will attempt to be captured in addition to any resources captured using the USE or GET in activity logic.
