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 Category	Description
Not Loaded	The resource has capacity, but no work load.
Partially Loaded	The resource work load is less than its capacity.
Fully Loaded	The resource work load equals its capacity.
No Capacity Load	The resource has work assigned on a day without capacity.
Overloaded	The resource work load exceeds its capacity.
Past Due	The 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:

• Load Source - Controls what different types of load that should be considered. This affects both the load category classification, and the visibility of operations.
• Capacity Type - Controls whether the capacity used to calculate the load category should consider the work center utilization or not.
• Operation Selection - Controls whether to show only operations from the search/chart filter, or all operations within the search/filter interval.
• Color By - Controls the color of the operations. Some color by options are only applicable for shop order operations, non-shop order operations will then be displayed using a grey color. Discrete characteristic codes will appear as color by options when they have been connected to a work center from the search result.

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

Load Source	Explanation
Planned	Operation from a planned shop order.
Released	Operation from a released shop order.
Started	Operation from a started shop order.
Parked	Operation from a parked shop order.
Maintenance	Maintenance 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.
DOP	CRP scheduled operation from an unreleased DOP order.
Requisitioned	CRP scheduled operation from a shop order requisition.
Master Schedule	CRP scheduled operation from a proposed master production schedule.
Production Schedule	CRP scheduled operation from a production schedule.
Promised	Operation from an capability check created interim order scheduled using IFS/APB.
Resource Break	Resource break scheduled using IFS/APB.

To limit the contents of this chart based on a selection made in another chart, open the settings dialog by clicking the gearwheel icon and select to filter from any of below charts:

• Material Availability Summary - Chart is filtered to only show resource availability and operations related to the shop order(s) of the selected availability category(s).
• Machine Availability Summary - Chart is filtered to only show resource availability and operations related to the selected work center resource(s), work center(s), department(s) or production line(s).
• Machine Load - Chart is filtered to only show resource availability and operations related to the selected load objects.

Prerequisites

• Machine operations originating from shop order, and/or generated by the capacity requirements planning must exist.
• To analyze resource availability, the Calculate Work Center Resource Capacity should have been performed for the site.
