Analyze Machine Load Chart
Explanation
This activity is used to analyze the machine load in relation to the capacity. Load is represented with bars per
day, or week and capacity with a line.
To populate the chart, click the magnifying glass and search either for relevant shop orders, or work
centers/time period depending on the page used. When searching for shop orders, chart will show all load for the
relevant work center resources and dates.
The chart can be configured using below settings:
- Group By - Controls how the bar segments should be divided.
- Color By - Controls the color of the bar segments. Only available when group by has been set
to Operation.
- Load Source - Controls what different types of load that should be considered.
- Capacity Type - Controls whether the capacity line should consider the work center
utilization or not.
- Load Dates - Controls whether load should be shown only for the dates on which the searched
data have load, or all dates within the searched data interval. Note that when Search Result is
selected, load for a date will only be fetched from the resources the searched orders loads that date.
Search Interval will fetch load from all resources in the search result for all dates.
- Aggregate By - Controls whether the X-axis should show load and capacity per day, or per
week.
- Show Only Load Dates - Controls whether the X-axis should show only dates with visible load,
or include also dates without visible load. Note that if Date Selection has been set to
Dates, load may exists on dates even if the load is not visible in the chart as it appears on a
date where the search result have no load.
When grouping / coloring by load sources, the below classification is used:
| Load Source |
Explanation |
| Planned |
Load from a planned shop order. |
| Released |
Load from a released shop order. |
| Started |
Load from a started shop order. |
| Parked |
Load from a parked shop order. |
| Maintenance |
Load from a maintenance work task. Note that below must be fulfilled to view maintenance load 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 |
Load from an unreleased DOP order. |
| Requisitioned |
Load from a shop order requisition. |
| Master Schedule |
Load from a proposed master production schedule. |
| Production Schedule |
Load from a production schedule. |
| Promised |
Load from a capability check created interim order scheduled using IFS/APB. |
| Resource Break |
Load from a 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 on the shop order(s) of the selected
availability category(s). I.e. only date interval and work centers connected to any operation on these shop
orders will be considered.
- Machine Availability Summary - Chart is filtered on the selected work center resource(s),
work center(s), department(s) or production line(s). I.e. Load and capacity will only be shown for the selected
items.
Prerequisites
- The machine capacity must have been calculated for the site using Calculate Work Center Resource
Capacity.
- To show loads from sources other then shop order, the capacity requirements planning must be performed for
the site using Perform CRP.
