The availability will be negative

[codeMark1]

When I manually input two reasons, the time periods are 00:00 ~ 15:00 and 00:10 ~ 14:00 respectively; The calculated availability is negative. How to deal with the problem of time overlap?

[point85]

Hello codeMark1, When entering availability data in summarized form over a time period (in your case 16 hrs and 18 minutes), you need to enter the aggregated time duration (in hours and minutes) for each availability reason. Attached is an example with a duration of 30 minutes for reason Unplanned2. Also attached is the dashboard Events tab in the Monitor showing an expected high availability.

In your case with the negative availability, you will need to examine the database event records for this time period (and also the last equipment setup) and correct them as necessary using the event editors.

Thank you for your answer；As shown in the figure below, I have another problem about time calculation，

There are two ways to calculate downtime

(1) The total time of 10:00 ~ 13:00 plus 11:00 ~ 12:00 shall be calculated; 4H

(2) Calculate the time between 10:00 and 13:00; 3H

How should we calculate it? If you follow the first method, will the calendar time be exceeded?

The equipment should register 3 hours of unplanned downtime (10:00 to 13:00) against it. Presumably the 1 hour lunch is taken by the operator(s) and the maintenance team would be working to get the equipment back up and running during this 3 hour period. However, if the operators normally make the equipment unavailable for this 1 hour, then that time would be included in unscheduled hours. It is best to look at what the equipment is doing over time, not the people.

I recommend obtaining a copy of the 'Understanding, Measuring, and Improving Overall Equipment Effectiveness" by Ross Kennedy - the book cited in the User's Guide. The time loss model in that book is how Point85 implements OEE.
