The Critical KPI to drive Manufacturing ProductivityJason Corder
A net reduction in cost of operations directly and positively affects the bottom line. Companies can boost revenue without sacrificing profitability by factoring in long-term debt-to capital ratio. Since finance puts a premium on a company’s ability to maximize productivity and use existing assets, you have to continually measure, analyze, and adjust your processes. This is accomplished by a rigorous practice of productivity gains, cost cutting with increased efficiencies, and maximizing returns on fixed assets.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

Why OEE?
1. April 2020
Outline
Overall Equipment Effectiveness or OEE is a method of looking at a
manufacturing process to determine how well it is operating. It
combines three metrics to provide a single measure that encompasses
the utilisation of an asset, if it is being run at its optimum speed, and
what proportion of scrap to good products are being produced.
OEE (%) = Availability (%) x Performance (%) x Quality (%)
10000
Savings
Unless you have a site that is already extremely efficient, in virtually all
cases that I have come across it is possible to get a payback for a
system in just a few weeks. After that you are saving money and
improving your bottom line.
Generally there are also benefits realised that were not apparent
initially. For example, with one timber mill, it was presumed that the
operator on one of their stackers was stood waiting for about 1½ hours
in an 8 hour shift. After an automatic OEE system was installed it
became clear that it was actually 4½ hours. As a result their process
was adjusted to build up a buffer and the operator redeployed on
other tasks during their ‘newly available’ time.
When not to implement
Implementing an OEE system will not inherently make you more
efficient or save you money. The only way to make it work is if you
actively use the data it generates.
Ideally more than one member of staff should champion the process.
Otherwise if that person is busy or if they leave, you are left without
appropriate knowledge and the system is unlikely to be successful.
You also need buy-in from the top management all the way down to
the shop floor. Fundamentally you need to be committed to it, or you
will just be wasting your time and money.

environment.

OEE Machine Downtime Manufacturing Information Systems
2 Available or not…
The availability metric immediately brings up some interesting
differences in possible approach. From the production plan point of
view, operators are expected to be running their assets according to a
defined shift pattern with allowances for breaks, clean up times etc.
This gives an amount of available time for running on each asset. It
can, however, make it complicated when, for example, operators are
off sick, the production plan needs to change on the fly, or an
impromptu meeting is held. Ultimately this leads to an increased
administration requirement which, in my experience can result in the
system falling out of favour as the overhead is too onerous.
I think in most cases it is better to handle the planned not to run
periods by using simple concepts such as identifying when an operator
is not logged on to an asset. Then there is no additional administration
and logging on can be enforced through the use of machine interlocks.
What is the target speed?
Takt or cycle times for machines can be well defined but that is only
the start of the story. Production planning systems will calculate how
many products of a particular type can be manufactured in a given
amount of time. They take into account changeover and clean down
times, and include timings for bringing raw materials to an asset and
taking finished goods away. This gives most sites their performance
targets. However, I have seen many cases where the data in the
ERP/MES is based on historic hearsay and is not particularly accurate.
A little while ago, I was stood with a production manager at a site
looking at a machine with a speed measurement above it of about 200
m/hr. I questioned how they knew if it was running at the correct
speed and what the target speed was. The discussion progressed to
the fact that when the machine was installed the manufacturer said it
could run at 800 m/hr, as the machine was now quite old they had
recently said that they thought that it would probably be capable of
400 m/hr. “Ok” I said, “but why is it running at 200?”. “That’s a good
question” was the response…
The target speed for each product should be reviewed and if there is
uncertainty about them then data needs to be collected initially to
allow an accurate figure to be determined and then fixed.
Availability
is an indication of the
time that an asset is
running.
It is calculated as the
operating time as a
percentage of the planned
production time
(otherwise known as
available time).
Performance
is an indication of how
close the asset is running
to its target production
rate for the product being
made.
It is calculated as the
number of products
produced as a proportion
of the possible number of
products that could have
been made in the running
time.

OEE Machine Downtime Manufacturing Information Systems
3 Quality products
OEE accounts for the quality metric with exactly the same weight as
availability and performance, however, in most instances the early wins
at a site do not initially come from targeting quality issues. That is not
to say that it should be ignored though. If you speed up production to
improve performance, you may inadvertently reduce the quality.
Ideally if the quality metric is not going to be targeted initially, I would
suggest using a nominal value, for example, defining a percentage of all
products manufactured to be scrap.
World class performance?
World class performance is often quoted at 85% but the reality is that
it is wholly dependent on the manufacturing process for a particular
type of product. In some cases a 50% OEE may be exceptional.
Ultimately, OEE is a benchmark that should be used to determine
whether a site is making improvements or not. It doesn’t matter if the
actual value is 85% or 25%.
Paper based data collection
Manual, paper based systems allow users to become familiar with the
concepts of OEE and are, therefore, a good starting point. However,
they have two key issues:
1. It can require a significant amount of time to interpret handwriting
and transcribe it into a tool that can be used to analyse the data.
2. Human nature would inherently mean that the data is not accurate.
If I was running an asset, my focus would be manufacturing
products, not filling in a form. If I reached the end of an 8 hour
shift and realised that I had made 500 products instead of 1000, I
would assume that it would be because I had 4 hours of
breakdown. I would be unlikely to remember how long any period
of stoppage was for and every reason that the asset stopped.
An automatic system will accurately timestamp each stoppage event
and can be used to force reasons to be entered at the time they occur.
This leads to better data that can be automatically analysed.
Quality
is an indication of how
well the products are
being made.
It is calculated as the
number of good products
as a proportion of the
total number that were
started.
OEE
OEE is a widely used
analysis and
benchmarking metric.
World class sites are
regarded as an 85% or
above OEE, and the
average OEE is around
65%.

OEE Machine Downtime Manufacturing Information Systems
4 What about manual assembly?
Although tracking OEE for a manual assembly process is inherently
dependent on an operator entering accurate information, there is no
reason why it cannot be monitored so that data is collated
electronically and automatically processed, meaning that there is only
minimal administration required.
If you also look at minimising operator interactions using barcode
scanners, RFID readers, and the integration of the OEE system with
production planning to get works orders / jobs automatically, then
there are some significant additional benefits to be realised.
Response times
In order to improve, one of the key areas to address is response times.
This may be simply highlighting to management when an asset has
been stopped for an extended period of time, or improving the
notification / call out mechanisms available for maintenance staff.
For longer stoppages there is often a disagreement between
production and maintenance about how long a breakdown took to
repair. Recording call out and response times allows these period to be
analysed in more detail to determine, for example, if there are
sufficient maintenance staff on a night shift.
In addition, allowing operators to request raw materials or their team
leader, direct from their asset can also result in shorter stoppages.
What about the detail?
In order to make improvements you will need to go from the 3 key
metrics into the data that they are made up of. For example,
• If the availability measure is low then you need to understand what
stoppages have occurred and why?
• If the performance metric is low, you need to be able to review the
data to determine what is happening and potentially see the
reasons for slow speed running.
• If the quality measure is low, what are the reasons for scrap?

OEE Machine Downtime Manufacturing Information Systems
5 Why OEE?
OEE is not a panacea but it is a great tool for identifying where issues
are and providing a means of seeing that improvements have been
made.
Implementing an OEE system that can be easily expanded over time to
cover more assets and include additional functional areas is a way of
instilling continuous improvement throughout the workforce.
After all, your competitors are improving and unless you continue to
become more efficient, you will get left behind.
