Shift handover summaries from machine events and operator notes

At a shift change, the outgoing supervisor tells the incoming one what happened. It works while the shift was quiet and the supervisor remembers. When Machine 4 stopped twice at 3 a.m., a die was changed and a batch was held, the verbal version loses details by the time it reaches the morning meeting.

Two sources, both incomplete

Machine events are exact but have no context. A controller records that the machine stopped at 03:12 and restarted at 03:40. It does not know why.

Operator notes carry the reason but are loose: a line in a notebook, a WhatsApp message, a word on a whiteboard. Times are vague and the wording changes from person to person.

A handover summary joins them. For each machine, the stop is matched to the operator’s note by time, so “03:12 to 03:40, 28 minutes, tool change” becomes one line.

What goes on the page

Keep it short enough to read in two minutes.

• Output against target for each line, for the shift.
• Stops longer than a set threshold, with duration and reason.
• Quality holds and rejects, with the batch or lot.
• Open items the next shift must act on, each with a name beside it.
• Anything unusual, such as a machine running outside its normal range.

If the summary is longer than a page, it will not be read.

Make notes easy to enter

The summary is only as good as the notes. A tablet beside the machine with five or six large reason buttons gets more entries than a free-text field, and a short note can be added on top. Typing during a busy shift is where compliance drops.

Timestamps should come from the machine event, not from when the operator got round to writing. If the operator taps a reason within a few minutes of a stop, the app links the two automatically.

Where an AI agent helps

A language model is good at turning a list of events and notes into plain sentences, and at grouping repeated stops on the same machine. We would build the agent to draft the summary and show the events behind each sentence. The supervisor reads it, corrects it and sends it. The agent does not decide what mattered to the plant. It states the numbers it was given, and a person owns the final text.

What it does not fix

If machines are not connected, there are no events to summarise, and the page is only as good as the notes. If operators skip the reason entry, a gap shows up as “unexplained stop”, which is at least visible. A summary also does not replace a short conversation at the machine when something is in progress. It makes sure the facts for that conversation are in front of both people.
