Planta Scheduling API Reference

Die nachfolgenden Inhalte sind nur in englischer Sprache verfügbar.

The scheduling functionality is accessible using the module scheduling.
To use it, just put import scheduling in the code that is to be run by PLANTA Server.

SchedulingType

Enum Name	Enum Value	Comment
CAPACITY_SCHEDULING	0	capacity scheduling
UNLOAD_SCHEDULING	1	unload project
TIME_SCHEDULING	2	time scheduling

Scheduling Convenience Functions

All of the following functions take either

(technical) project id arguments, e.g. scheduling.unload('4711', '4811'), or
an iterable of technical project ids, e.g. scheduling.unload(['4711', '4811'])

They return nothing (None)
Projects that cannot be found are silently skipped!

Function Name	Comment
`unload()`	Unload the given projects
`reschedule()`	Do a rescheduling on the given projects
`schedule_capacity()`	Capacity scheduling
`schedule_time()`	Pure time based scheduling

Internal Scheduling Functionality

Function Name	Parameter Description	Comment
`schedule(seq, sched_action, rescheduling)`	`seq`: iterable (technical project ids) `sched_action`: see `SchedulingType` `rescheduling`: boolean	For internal use only

Effort Distribution

Function Name	Parameter Description	Comment
`distribute_effort(seq)`	`seq`: iterable containing dtp records from table 801	For internal use only

Simulation

Simulation class

The Simulation class adds a bit of syntactic sugar to the simulation API as it provides indirect access to the simulation API and automatically clears the simulation on __exit__.

Method	Parameter(s)	Return Value	Comment
`add_relation()`	`project`: project uuid `activity1`: predecessor uuid `activity2`: successor uuid	none	Add relation to simulation environment.
`remove_relation()`	`project`: project uuid `activity1`: predecessor uuid `activity2`: successor uuid	none	Remove relation from the simulation environment.

Direct usage of the simulation API is also possible.

Function Name	Parameter Description	Comment
`simulation_add_relation(project, activity1, activity2)`	`project`: project uuid `activity1`: predecessor uuid `activity2`: successor uuid	Add relation to simulation environment.
`simulation_remove_relation(project, activity1, activity2)`	`project`: project uuid `activity1`: predecessor uuid `activity2`: successor uuid	Remove relation from simulation environment.
`simulation_clear()`		Clear simulation environment.

Cycle Check

Function Name	Parameter Description	Comment
`project_has_cycle(project)`	`project`: project uuid	Returns `true` if the project contains cycle, `false` otherwise (respects simulation environment).
