Analyze Machine Availability Summary Chart

Explanation

This activity is used to analyze the worst case machine availability on a high level for a work center resource, work center, department or production line using a pie chart.

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 the work centers connected to any of the operations on those shop orders.

A pie segment represents either a work center resource, work center, department or production line depending on the selected group by option and is assigned a load category based on below logic:

Load Category	Work Center Resource	Work Center	Department	Production Line
Not Loaded	The resource has capacity, but no workload.	The work center has capacity, but no workload.	None of the work centers connected to the department have any workload.	None of the work centers connected to the production line have any workload.
Partially Loaded	The resource has workload less than its capacity for all days/weeks.	The work center has workload less than its capacity for all days/weeks.	All of the work centers connected to the department have workload less than their capacity for all days/weeks.	All of the work centers connected to the production line have workload less than their capacity for all days/weeks.
Fully Loaded	The resource has workload that equals its capacity on at least one day/week.	The work center has workload that equals its capacity on at least one day/week.	At least one of the work centers connected to the department has workload that equals its capacity on at least one day/week.	At least one of the work centers connected to the production line has workload that equals its capacity on at least one day/week.
Unbalanced	N/A	One or more of the resources on the work center is overloaded on at least one day/week, but the workload does not exceed the capacity on a work center level. I.e. the workload can be balanced by splitting the work between the resources.	At least one of the work centers connected to the department has one or more resources that are overloaded on at least one day/week, but the workload does not exceed the capacity on a work center level. I.e. the workload can be balanced by splitting the work between the resources on the work center.	At least one of the work centers connected to the production line have one or more resources that are overloaded on at least one day/week, but the workload does not exceed the capacity on a work center level. I.e. the workload can be balanced by splitting the work between the resources on the work center.
Overloaded	The resource workload exceeds its capacity on at least one day/week.	The work center workload exceeds its capacity on at least one day/week.	At least one of the work centers connected to the department has workload that exceeds its capacity on at least one day/week.	At least one of the work centers connected to the production line has workload that exceeds its capacity on at least one day/week.

The chart can be configured using below settings:

• Load Source - Controls what different types of load that should be considered.
• Past Due Load - Controls whether or not load in past due time should be considered. If considered, the entire past due load is considered on the first date with load in present time.
• Capacity Type - Controls whether the capacity should consider the work center utilization or not.
• Load Dates - Controls whether only the dates on which the searched data have load, or all dates within the searched data interval should be considered.
• Aggregate By - Controls whether the load and capacity should be compared per day, or per week to set the load category.

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 below chart:

• 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.

Prerequisites

• The machine capacity must have been calculated for the site using Calculate Work Center Resource Capacity.
• To consider loads from sources other then shop order, the capacity requirements planning must be performed for the site using Perform CRP.
