What is a process layout?

A process layout is used for factories or service facilities dealing with a variety of products that follow different pathways through the facility.

How is the systematic layout planning method used?

The systematic layout planning method, or closeness ratings, determines which departments should be placed near or apart based on specific criteria.

Who created the systematic layout planning method?

The systematic layout planning method was created by Richard Luthor.

What do closeness ratings determine?

Closeness ratings determine which departments absolutely must, should, or cannot be next to each other.

What happens if departments that shouldn't be near each other are placed together?

Unsafe or inefficient conditions may arise, such as health risks or workflow bottlenecks, making it crucial to separate certain departments.

What visual diagram is used to plan facility layouts?

A stick diagram is used to help visualize the placement and relationships between departments in a facility layout.

What are 'A', 'E', and 'X' in closeness ratings?

'A' indicates departments that must be next to each other, 'E' is preferable but not critical, and 'X' means they must not be next to each other.

Why is department 6 significant in this example?

Department 6 appears most often in the criteria list, influencing its placement to prioritize its relationships with others.

What is the purpose of folding the stick diagram?

Folding the stick diagram helps visualize and adjust the spatial arrangement of departments to fit within the available facility space.

Can corner placements count as departments being close to each other?

Yes, departments that share a corner can be considered close in the context of layout planning.

TLDRIn this instructional video on facility layout planning, the focus is on using the process layout approach, a method particularly suited for dealing with varied products and processes. This necessitates determining the optimal location of various departments within a building. The core strategy introduced is the systematic layout planning method, also known as closeness ratings, invented by Richard Luthor. This approach involves evaluating which departments need to be positioned next to one another, which should ideally be close, and which must remain separated. This determination is made based on several criteria such as safety requirements, shared equipment, or workflow dependencies; for instance, separating toxic paint areas from customer service zones in a body shop. The video illustrates a practical example of constructing closeness ratings through visual diagrams, identifying A's, E's, and X's that represent different proximity needs. It explains step-by-step how to translate these diagrams into spatial layouts that adhere to the planning criteria, using stick diagrams to depict and rearrange departmental relationships within a given space.

The discussion focuses on process layouts in facilities, emphasizing that not all work processes will follow the same path through a facility. The systematic layout planning method, developed by Richard Luthor, utilizes closeness ratings to determine which departments must be near or far from each other. Different closeness ratings criteria such as 'A', 'E', and 'X' indicate essential proximity, importance of proximity, and the necessity to avoid proximity, respectively. The process involves identifying these ratings and using them to plan facility layout, focusing on safety and effectiveness of operational processes.
00:05:00 - 00:11:28
The explanation in this section further illustrates how to apply these closeness ratings to actual facility planning. It outlines the process of identifying department pairings according to the ratings 'A', 'E', and 'X', focusing on safety and operational efficiency. Once ratings are assigned, planners must place departments with 'X' ratings on the edges to prevent unwanted proximity. The uses of a stick diagram are detailed to visually guide the placement of departments in a manner that respects all proximity requirements. The goal is to adjust and fit the diagram into the facility layout while honoring all assigned closeness ratings.

00:00:00
if you have a process layout then when
00:00:03
you are looking at your facilities so
00:00:05
let's say here's your building you need
00:00:08
to decide what department is going to be
00:00:11
located where and when it has processed
00:00:15
when you have a process layout you need
00:00:16
to recognize that not all of your work
00:00:19
in process will follow the same process
00:00:22
or a movement through your facility some
00:00:26
of your material might go this way
00:00:29
others might go that way depending on
00:00:32
what needs to be done so process layouts
00:00:35
are used for services they are used when
00:00:38
there is variety in the products that
00:00:41
you're producing so each step is not the
00:00:45
same for each product so you take the
00:00:47
inventory the work in process to where
00:00:49
it needs to be for the jobs that need to
00:00:52
be done well as part of this we need to
00:00:54
figure out the location of those
00:00:56
different departments we want to look at
00:00:59
now is the closeness ratings or
00:01:02
systematic layout planning method this
00:01:07
systematic layout planning method or
00:01:09
closeness ratings
00:01:10
we're created by a guy named Richard
00:01:11
Luthor and what they do is they look at
00:01:18
which departments can and can't be next
00:01:22
to each other based on preset criteria
00:01:32
so let's just move it forward here in
00:01:34
the slides to our discussion on those
00:01:37
closest ratings and what you see here is
00:01:42
you see a diagram that shows in this
00:01:44
case six different departments and you
00:01:47
see on this diagram we have a ZZZ and
00:01:50
X's A's are the departments that
00:01:54
absolutely must be next to each other
00:01:57
YZ it's important that they're next to
00:02:00
each other but not critical
00:02:01
so if given the option we need to put
00:02:04
them next to each other if we can but if
00:02:06
we can't they're kind of second priority
00:02:09
compared to the A's the X's are the
00:02:12
departments that
00:02:13
absolutely cannot be near each other so
00:02:17
maybe is unsafe work conditions for
00:02:20
these two departments to be near each
00:02:22
other for example if you're a body shop
00:02:24
the departments like where your
00:02:28
customers go to pay cannot be next to
00:02:32
where you are spraying toxic paint right
00:02:34
unsafe conditions so you need to keep
00:02:37
them separated maybe there's separate
00:02:39
ventilation for example so you may have
00:02:42
a number of criteria that decides
00:02:44
whether something absolutely must be
00:02:46
next another Department so an a is
00:02:49
important but not critical in E or is
00:02:53
cannot is be next to each other at all
00:02:55
it's undesirable in X these may be
00:02:59
factors such as whether or not they use
00:03:01
the same equipment do they share some of
00:03:03
the same personnel we can look at the
00:03:06
level of workflow between the level of
00:03:08
communication if some where jobs are
00:03:11
performed and then of course if there is
00:03:13
unsafe or unpleasant conditions if
00:03:16
departments are near each other so what
00:03:18
we do is we take this diagram that shows
00:03:22
the A's the ease and the X's and we can
00:03:25
use it to layout our facility so let's
00:03:29
suppose at our facility so here's our
00:03:35
six locations and here's they would how
00:03:37
they would be laid out what we need to
00:03:39
do first is identify the pairs of a ease
00:03:44
and X's let's go back so how do you
00:03:50
figure out if something as an a well if
00:03:52
you look here at this box it has an a
00:03:55
notice that one of the sides of the box
00:03:59
points the department one and the other
00:04:02
side of the box points the department to
00:04:04
so one and two that pair is an A if we
00:04:10
look at this a here notice that this
00:04:13
side of the box goes to Department one
00:04:15
and this one goes to Department three so
00:04:18
here we have an a4 one and three
00:04:27
now we have an e here notice that the
00:04:30
edges of this ebox one goes to two and
00:04:33
one of the edges goes to Department
00:04:36
three so Department - and Department
00:04:38
three are YZ - 3 is an e here we have an
00:04:43
X one edge of the x box goes the
00:04:47
Department one's the other edge of the x
00:04:49
box goes to Department 4 so 1 and 4
00:04:52
cannot be near each other let's look at
00:04:56
this X here the edge of this x box goes
00:05:00
to Department three the other edge goes
00:05:02
to 4 so 3 & 4 cannot be near each other
00:05:08
let's go and do the rest of them here's
00:05:10
a so Department 3 and Department 5 are
00:05:15
A's when it comes to the a that we see
00:05:21
here this is Department - and Department
00:05:26
6 here we have an X and this goes with
00:05:33
Department 3 and Department 6 and this a
00:05:40
is Department for and Department 6 and
00:05:47
the last one here is Department 5 and
00:05:51
Department 6 RNA notice that some
00:05:57
departments we have no preference we
00:05:59
don't care either way and so there is no
00:06:01
a or E or X for some of these
00:06:04
combinations so we only need to focus on
00:06:06
what absolutely must be next to each
00:06:08
other
00:06:09
what is important to be near each other
00:06:11
and what cannot be near each other at
00:06:14
all
00:06:15
whatever you put into this X category
00:06:17
this will these are typically end up
00:06:20
being in your corners okay the other
00:06:23
thing we want to look at is which
00:06:27
department has the most criteria the
00:06:30
most restrictions so notice as we look
00:06:33
at these notice that six appears three
00:06:36
times in the a column and one time in
00:06:39
the
00:06:39
x-column so when you start to lay out
00:06:42
your diagram you should start with the
00:06:45
six because it appears the most often
00:06:48
and then you want to start to kind of
00:06:50
lay out this relationship here so let's
00:06:55
start with the six is six and two six
00:06:57
and four six and five those all need to
00:07:00
be near each other
00:07:01
notice that the four is also appear in
00:07:04
the X's so let's put four out here to
00:07:07
the left and we have a six and A two we
00:07:14
have a six and the four and the six and
00:07:17
A five
00:07:18
okay so here these three branches
00:07:22
indicate that these four departments
00:07:25
need to be touching so we've taken care
00:07:28
of this one and this one and this one
00:07:30
and we put four out on the left side
00:07:32
there because it's appearing in the exes
00:07:35
okay
00:07:36
so we'll come back to that issue in a
00:07:37
moment all right let's check out the
00:07:39
rest of them here we're going to need a
00:07:42
three and a five let's put a 3 here
00:07:46
we're going to need a 1 and a 3 notice
00:07:51
that one is also appearing out here in
00:07:54
the X's along with the 3 so let's put
00:07:58
bears at 1 & 3 1 & 3 need to touch one
00:08:07
in 4 can't so we want them to be far
00:08:08
away from each other okay
00:08:11
1 & 2 need to touch so let's click the
00:08:15
line there so we have 1 & 2 1 & 3 3 & 5
00:08:20
2 & 6 4 & 6 5 & 6 let's also do our 2
00:08:25
and our three okay and so as we are
00:08:29
filling out this diagram here 1 & 4
00:08:31
cannot be near each other 3 & 4 cannot
00:08:35
be near each other & 3 & 6 cannot be
00:08:38
near each other so we're going to do is
00:08:40
you're going to take this little stick
00:08:41
diagram here and you're going to fold it
00:08:44
into the box and we fold it into the box
00:08:48
we want to think about taking this image
00:08:50
here and rotating it or
00:08:53
it until it lays nicely in here so think
00:08:57
of these little sticks well to fix
00:08:59
connecting these numbers and you can
00:09:02
bend them in different directions to
00:09:04
fold them in so let's put our four here
00:09:08
in this corner
00:09:09
because four has things that can't touch
00:09:12
like the one and we have an issue as
00:09:17
well that threes cannot be near anything
00:09:20
so likely we're going to have our ones
00:09:23
and threes be over here because they
00:09:25
can't be near the four and the three
00:09:28
can't be near the six so let's fold this
00:09:30
in
00:09:31
by taking this straight line here and
00:09:33
turning it into that straight line there
00:09:36
okay so when you do that we then need to
00:09:40
take the rest of this piece and fold it
00:09:43
so we have six and two and six and five
00:09:45
so here's the two and the five they are
00:09:48
touching so we maintain that piece there
00:09:52
and then we have our three and our one
00:09:55
so number five and three need to touch
00:10:00
three and one and two and one so notice
00:10:03
if we put three here and one there then
00:10:06
the two and one are so good the one and
00:10:11
three are still good the two and three
00:10:13
are still good and essentially you can
00:10:16
see that bit of that stick diagram fold
00:10:19
it into the box
00:10:20
you should always double check your X's
00:10:23
afterwards one and four are nowhere near
00:10:25
each other three and four are nowhere
00:10:27
near each other and three and six now to
00:10:31
be close to something it can be on
00:10:33
either side or it can be at a corner as
00:10:37
well to count so you see how we have
00:10:40
filled in the department based on which
00:10:44
departments need to be next to each
00:10:45
other which ones cannot using our
00:10:48
closeness ratings if you double check
00:10:52
this and you find that it does not fit
00:10:54
with X then go back to your stick
00:10:56
diagram and again try to fold it into
00:10:58
the box you should look for what can't
00:11:02
touch each other like once fours and
00:11:04
threes here and those should be on the
00:11:06
outside
00:11:06
side six is also here they're not always
00:11:09
on the outsides of the box but a good
00:11:12
majority of them will be because that's
00:11:14
the only way you're going to get them
00:11:15
not to interact with other departments
