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.
