You are here: Building the Model: General Elements > Resources > Resource Downtimes
Resource downtimes refer to the times when a resource is unavailable due to scheduled events like breaks and shift changes, or unscheduled events like illness and random failures. For scheduled events, it is much easier and more straightforward to define these downtimes using the Shift Editor (see Shifts & Breaks). Unscheduled downtimes, based on the elapsed time of the simulation clock or resource usage time, are defined in the Resources edit table by clicking on the downtime heading button.
How to define resource downtimes:
1. Select Resources from the Build menu.
2. Select the resource for which the downtime is to be defined.
3. Click the DTs... button from the Resources edit table.
4. Select the downtime basis: Clock or Usage.
5. Enter the required information in either the Clock Downtime or Usage Downtime edit table. Each of these tables is described in the following pages.
Please note
Unlike location downtimes, multiple resource downtimes occurring within the same time frame are processed sequentially, not concurrently. However, through the use of the DTDelay function, concurrent downtimes can be achieved for resources.
