Maintenance Schedule

Provides for the capture of all information that defines the maintenance schedule.
For technical detail, refer to fp_control_maintenance_plan.
All of the following information can be asserted through the functional part but is identified in sub-groups for convenience.

Task

	Set the globally unique identifier and owner history for the task. These should be handled directly by the software application and should not require action by the user.
	Specify a name for the task that can be used as its representation in a plan or schedule.
	Set the value of the task identifier. This is locally unique (within the maintenance plan), that may be used as a sequence number in a list of tasks 1,2,3,4 etc. or as work breakdown structure identifier.
	Identify if the task is a milestone. Although this value must be asserted, it is not relevant to the maintenance plan. To ensure that it is not taken into consideration, it must be asserted as FALSE for a maintenance plan.
	Set the current status of the task.
	Specify the method of work to be used in carrying out the task.
	Set the relative priority of the task (in comparison to the priorities of other tasks).

Asset-Task Assignment

The asset(s) to which tasks are to be assigned are already identified through the preconditions for this exchange requirement.

	Select the asset(s) to which the task is to be assigned.
	Select the tasks that are to be assigned to the asset.
	Set the globally unique identifier and owner history for the relationship between the asset(s) and the task. These should be handled directly by the software application and should not require action by the user.
	Specify a name that can be used to identify the asset-task relationship. For example 'Change filter in AHU1' gives the task and the name of the asset on which it is carried out.
X	The quantity of the an object specific for the operation by this task MUST NOT be used in a maintenance plan.

Work Schedule

	Set the globally unique identifier and owner history for the work schedule. These should be handled directly by the software application and should not require action by the user.
	Specify a name for the work schedule that provides a 'human' readable identification.
	Set the value of the work schedule identifier. This may be used in for 'human' readable identification in conjunction with the name.
	Set the date on which the work schedule was created or modified.
	Set the name of the authors of the work schedule.
	Decide if the work control type is baseline, planned or actual (or some other user defined value in which case, the user defined value must also be specified).
	Set the total duration of the entire work schedule.
	Set the total time float of the entire work schedule.
	Set the start time of the schedule.
	Set the finish time of the schedule.

Work Schedule - Task Assignment

	Select the work schedule to which the tasks are to be assigned.
	Select the tasks that are to be assigned to the work schedule.
	Set the particular type of the work schedule/task assignment relationship which must be PROCESS.
	Set the globally unique identifier and owner history for the relationship between the work schedule and the tasks. These should be handled directly by the software application and should not require action by the user.
	Specify a name that can be used to identify the work schedule-task relationship.
	Set the time related information for either the BASELINE or the ACTUAL schedule as set out below.

Baseline Schedule

	Set the earliest date on which a task can be started.
	Set the latest date on which a task can be started.
	Set the date on which a task is scheduled to be started.
	Set the earliest date on which a task can be finished.
	Set the latest date on which a task can be finished.
	Set the date on which a task is scheduled to be finished.
	Set the amount of time which is scheduled for completion of a task.
	Set the amount of time remaining to complete a task.
	Set the amount of time during which the start or finish of a task may be varied without any effect on the overall programme of work.
	Set the difference between the duration available to carry out a task and the scheduled duration of the task.
	Set a flag which identifies whether a scheduled task is a critical item within the program.
	Set the difference between the late start and early start of a task.
	Set the difference between the late finish and early finish of a task.
	Set the extent of completion expressed as a ratio or percentage. This value must be set to 0 for a baseline schedule.
X	The date on which a task is actually started CANNOT be set for a baseline maintenance schedule.
X	The date on which a task is actually finished CANNOT be set for a baseline maintenance schedule.
X	Theactual duration of a task is actually started CANNOT be set for a baseline maintenance schedule.
X	The date or time at which the status of the tasks within the schedule is analyzed CANNOT be set for a baseline maintenance schedule.

Actual Schedule

Note that values that have previously been set in a baseline schedule may be subject to variation in an actual schedule.

	Set the earliest date on which a task can be started.
	Set the latest date on which a task can be started.
	Set the date on which a task is scheduled to be started.
	Set the earliest date on which a task can be finished.
	Set the latest date on which a task can be finished.
	Set the date on which a task is scheduled to be finished.
	Set the amount of time which is scheduled for completion of a task.
	Set the amount of time remaining to complete a task.
	Set the amount of time during which the start or finish of a task may be varied without any effect on the overall programme of work.
	Set the difference between the duration available to carry out a task and the scheduled duration of the task.
	Set a flag which identifies whether a scheduled task is a critical item within the program.
	Set the difference between the late start and early start of a task.
	Set the difference between the late finish and early finish of a task.
	Set the extent of completion expressed as a ratio or percentage. This value must be set to 0 for a baseline schedule.
	Set the date on which a task is actually started.
	Set the date on which a task is actually finished.
	Set the actual duration of a task is actually started.
	Set the date or time at which the status of the tasks within the schedule is analyzed.
