View line utilization counts and durations

On the Utilization Counts/Duration Pareto graph, you can view either the counts or duration of the utilization states, reason groups, or reasons for the bottleneck entities in the line that were used for OEE calculations.

Note that if there are parallel entities involved in a bottleneck position during the selected time period, then the sum of the durations for all the events will be greater than the time period duration.

Also, events for an entity that are immediately adjacent to the period during which that entity was a bottleneck for the line are included in the graph of event counts. However, these events do not contribute any time to the graph of event durations because they do not actually extend into that period. So if an entity that is changing into or out of a utilization reason and is disabled causes the bottleneck to move to or from that entity’s position on the line, that utilization event will be counted even if no additional time for it is added to the duration for its state, group, or reason.

Toggle between the two viewing modes

• Click the graph’s Show Duration/Show Counts button.

Drill down into the count or duration information

• Click a bar in the graph.

The drill-down sequence of information is:

1. Utilization states (the initial display, shown above)

2. Reason groups for the selected utilization state

3. Reasons for the selected reason group
