DownQty()

General System Function

Syntax samples

DOWNQTY(<location> or <resource>>)

IF DOWNQTY(Loc1) > 3 THEN ROUTE 2

DISPLAY "Total Res1 Down Now:" $ DOWNQTY(Res1)

Description

Returns the number of location or resource units down at the time of the call. Use this function to make decisions based on how many resource or location units are down. For example, if too many units are down, a foreman could preempt several units back into service.

Valid In

Any logic and all fields except those fields evaluated at translation only. For a list of the fields evaluated only at translation, see the Appendix A.

Components

<location>

The name of the location to examine. LOC() can be substituted for the name of a location.

<resource>

The name of the resource to examine. RES() can be substituted for the name of a resource.

Example

Two resources, Welders, weld brackets onto steel frames at a location, Man_Weld, in 6.5 minutes. An automatic welding machine, Auto_Weld, can perform the same task, but it takes 9.3 minutes. However, if only one Welder is available and the other Welder is down (e.g., on break), it takes one Welder 13.0 minutes to weld the brackets to the frames. Therefore, if one Welder is down, the frames should route to the automatic welding machine, Auto_Weld.
