In Exercise 10 we want
you to perform a Cycle Time Analysis for
your digester units, and let's see how we might build that.
I am in ProcessBook. I have got a, a blank display,
and I am going to draw my Batch Group on the screen.
So, I will select Draw Batch Group and draw a big square.
And, what I want to do is
use my digesters. So I will use
Digester,
and then *, or wild card,
for the Unit Name. And, I want
to go into the Layout Tab and I, I
will not need a Trend for this. So, I am going to delete the Trend.
But I do want the Search Results 'cause I want my users to be
able to, to -- I want my users to be able to change
their Search and pick different digesters. So, I am
going to configure this to contain nothing except
for Unit Name in the Search.
And so we should have a really big Search,
really big Search Criteria with
just the Unit Name as the attribute
to search for. And so, I will click OK.
And what I will get is my
Gantt Chart on the right, and my Search Criteria on the left.
I like to move those around a little bit, so I am
going to select only
my Gantt Chart Option -- oop, I need to be in
Build Mode -- select only the Gantt Chart,
shrink that down just a little bit, and then
move that a little wider. And now
I have a display where I can set
one of my digesters, and I can
see only that particular piece of information.
Now, this is a, a Relative Display,
so it does not allow me to see my actual
Cycle Time Analysis. But, you can see
that when I change the Gantt
Definition -- if I go into Layout
and configure my Gantt Definition -- oops --
go into Settings and configure my Time is Absolute,
I want to use the Full timestamp,
and I want to click OK.
This will allow me to, in Run
Mode, see my
different Cycle Time Analysis. So, if I,
if I were to go back over the last day, you would see
all the Times. Now, if I wanted to do
something a little bit more reasonable, and I
could see -- I wanted to see my Down Times a little bit more effectively,
I might change this, I might change this
Gantt Chart or -- I am sorry --
my Duration to something like,
oh, let's say, six hours,
Now minus six hours.
And there we can see for our digesters
there are clearly holes, and if I wanted to see
for a particular digester, I could
change my digester to that, and, and I could
see clearly that there's a hole here. That hole
represents about 54 minutes where
my digester was not functional.
Here's another hole here. If I
highlight that --
let's see if I can get that square right in there --
oh, it's not going to give me any data for that, is it?
53 minutes
where I can see that was, was
not running. So, you can see
either for both your digesters
or for one or the other, you can very easily see that.
BatchView makes it really easy
to do things like Cycle Time Analysis. This is
where you use a Gantt Chart, and you
change the Relative Time Display to an Absolute Time Display.
This really highlights holes or downtime
in your processes.
You basically see something
that looks like this, and you can use
your Zoom Function to zoom in and see exactly
what that Time Range was
for that particular example.
