Analyze Machine Operations Scheduling Chart

Explanation

This activity is used to analyze the availability of work center resources, and the scheduling of machine operations using a Gantt chart.

To populate the Gantt, click the magnifying glass and search for relevant shop order operations. Gantt will be populated with shop order, CRP and APB scheduled operations planned on the work centers related to the searched data. Operations will be populated for a date range corresponding to the earliest start of any searched data minus one day, to the last finish of any searched data plus one day to support rescheduling to previous/next day.

To analyze the availability of a resource, study the collapsed Gantt rows. Details can be viewed from the card by clicking the Gantt object. The availability of each resource and day is illustrated using below load categories:

Load CategoryDescription
Not LoadedThe resource has capacity, but no work load.
Partially LoadedThe resource work load is less than its capacity.
Fully LoadedThe resource work load equals its capacity.
No Capacity LoadThe resource has work assigned on a day without capacity.
OverloadedThe resource work load exceeds its capacity.
Past DueThe resource work load appears in past due time.

To analyze the scheduling of machine operations, expand the Gantt row for the relevant resource. Operation details can be viewed from the card by clicking the Gantt object.

The Gantt can be configured using below settings:

When coloring operation by load category, below classification is used:

Load SourceExplanation
PlannedOperation from a planned shop order.
ReleasedOperation from a released shop order.
StartedOperation from a started shop order.
ParkedOperation from a parked shop order.
MaintenanceMaintenance work task. Note that below must be fulfilled to view maintenance from this chart:
  • The task should be connected to an object which represents a work center resource.
  • The operational status type on the task should be Obstructive.
  • Planned start and finish date on the task has to be defined.
  • The task status should be Under Preparation, Prepared, Released or Started.
  • The execution time (planned start/finish) needs to be defined on the task.
DOPCRP scheduled operation from an unreleased DOP order.
RequisitionedCRP scheduled operation from a shop order requisition.
Master ScheduleCRP scheduled operation from a proposed master production schedule.
Production ScheduleCRP scheduled operation from a production schedule.
PromisedOperation from an capability check created interim order scheduled using IFS/APB.
Resource BreakResource break scheduled using IFS/APB.
