User-writable scheduling rule support functions

This section presents the user-writable functions that support the actual rules that are written. Each function is applicable to a specific Scheduler event such as the start of the scheduling run, the creation of a new load, or saving output. By writing a function, you can embellish the processing that is performed when the associated scheduling event occurs. The scheduling functions which are invoked when given events occur during the scheduling, are presented in alphabetical order. These events are model load, model save, create and terminate a load, create a batch or regular in-process load, setup determination, and batch forming. For assistance in writing a function and installing a rule, see Section 2. The support functions are presented in the table below.

Function Name	Descriptioni
ucend	Called during exit from Scheduler
ucfin1	Called just before summaries are written in finalization
ucfin2	Called just after summaries are written
ucini1	Called after global variables are read
ucini2	Called after all input is read
ucjbtra	Called when an operation starts, finishes, gets interrupted or restarts after being interrupted
ucnwld	Called when a load is being initialized
ucnwor	Called when a job is being initialized
ucrlfb	Called when a forming batch load is released for processing
ucrstra	Called immediately before a resource changes to a new state
ucsini1	Called just before input is saved
ucsini2	Called just after input is saved
ucstib	Called when a new batch load is created while reading load status
ucstil	Called when a new load is created while reading load status
ucstring	Can be used in expressions throughout the scheduling model
uctmld	Called when a load is terminated
uctmor	Called when a job is terminated
ucvalue	Can be used in expressions throughout the scheduling model
ucwtsr	Called from setup time rules to determine whether setup is necessary
