Equipment stopping can only indicate status changes, but cannot automatically explain the reasons. Reason: Too many options will increase the burden of filling in, and too few options will not support improvement. Outage classification should start from the facts that can be judged on site, and collect the information required for subsequent analysis in layers.

How to arrange records and operations

First, register according to first-level reasons such as failure, material shortage, line change, planned shutdown, etc., and then relevant personnel will add specific equipment problems or business reasons. Allows selection to be confirmed at the start and completed review before closing the event. The reason dictionary is versioned, and the historical records retain the classification meaning at that time.

The start and end times of the shutdown should come directly from equipment events, and the reasons should be confirmed by the business position. The basis for manual adjustment of time must be explained, especially to prevent the time periods for several reasons from overlapping. Waiting for inspection and equipment failure may coexist. The company should agree on the selection method of the main cause instead of letting the person who fills in the form make arbitrary judgments. The main causes and accompanying conditions can be presented simultaneously during statistics. After the classification is modified, the new and old names are compared, so that analysts can understand the classification changes in cross-month reports.

Specific scenarios that need to be checked

Use common descriptions in real business to check whether the options are ambiguous, such as which category the waiting inspection should be classified into. During acceptance, check the summary of the duration of a period of downtime after it has been split multiple times, and check cross-shift events. The analysis page displays the proportion of unconfirmed reasons, reminding the team to complete the data before making a judgment.
