Editors note: Jonathan H. Markey is
president and chief executive officer of the North Jersey Media Group in
Hackensack, N.J., publisher of The Record and other New Jersey papers. In late
2002, Markey spoke at Ifras Printing for Profit conference in Munich,
Germany. His presentation focused on NJMGs use of computer modeling and
simulation tools for operations analysis. The following is an edited version of
his presentation.
We have recently discovered a simulation tool, or
computer-modeling concept, that can be quite beneficial in planning successful
capital projects. The application also helps us evaluate performance and measure
costs relative to expected results.
Integrating multiple functions
First some background: Several years ago we
embarked on an ambitious program to move our systems infrastructure to a more
technologically advanced status.
Our mission was to integrate multiple functions
into a more stable and integrated platform, thus enabling us to manage our
business more effectively. We also wanted our data to be available in real-time
and also have it serve as a foundation for future modeling.
In looking at our goal, we understood that in
many areas we would probably be forced to take technology and software from
other industries and adapt it to our needs.
Our first major effort involved the replacement
of our entire business system, replacing several vendors with a
single-enterprise resource planning system from SAP. That effort put a floor
under our ability to effectively do cost analysis for all operations.
It is within this progressive framework that The
Record started using computer modeling. We, like many other newspapers in the
United States, were looking into the increased zoning needs of our products and
knew we needed to improve our existing mailroom operations at our main facility.
Measuring performance
At that time, we had also started to look at
replacing our legacy buffer system. Our mailroom inserting operation also needed
to be overhauled. We felt we could improve our overall operation by decoupling
the press from the mailroom operation and wanted to see which vendors would be
able to provide a solution for our needs.
We wanted to be sure we could measure the
performance characteristics of the latest storage and inserting equipment on the
market. We sent out a request for proposal that asked how each individual
inserter or storage system would match up with the existing press and
distribution equipment. We needed to know the real-world performance
characteristics that would distinguish each system.

Before the overall mailroom capital request could be submitted, we wanted to
test the concept of decoupling the press and mailroom completely. And just as
importantly, we wanted to test the how well vendors equipment performed.
Simulation helped
To do that, we decided to simulate our mailroom.
We first built a model of our existing operation. At the same time, we began
researching which vendor we would use to supply computer-modeling software. Our
requirements were straightforward. The software had to be:
relatively easy to learn and implement;
run on standard PC and Mac platforms;
be inexpensive to purchase; and
not need support from the IT department to
run.
We looked at several simulation software packages
before choosing Extend, an application developed by Imagine That!, a vendor
based in San Jose, Calif.
Extend, a general-purpose package, is disarmingly
simple to package together. No computer programming is needed. It is an
icon-based system. And it is as simple or complex as you have time to make it.
Finally, Extend is affordable. It cost us about $10,000 to run the application
on a single workstation.
To represent a press, we used a generator icon
and set the output at 35,000 papers per hour. To represent an inserter we used a
machine icon set to insert papers at an average throughput speed of 12,000
papers per hour.
Between the two we placed a storage system
capable of collecting papers at an 80,000-per-hour clip.
As I already mentioned, our goal was to see what
happened if we decoupled the press from our existing mailroom. The first
operation we studied was buffering.
What we needed
We looked at three vendors Heidelberg, GMA/Muller
Martini and Ferag. From these suppliers we received the specs on the machines we
would put in, the speed that a system could handle straight off the press and
what the storage system could hold.
In the first round of information gathering, most
of the vendor-supplied specification information was inadequate to ensure system
performance and success. The speeds were averages and/or peak performance. What
we needed to know was how well the machines would perform day in and day out.
This was a critical point of discussion and debate and created new challenges
for the vendors.
We needed effective data to serve as the baseline
for the simulation process using the Extend engine. Without empirically
developed data, the use of simulation tools has diminished value.
Unfortunately, most of the information available
from vendors is based largely on engineering projections and theory. As a
result, it makes the outcome of any simulation much less reliable. We were able
to offset that, however, by feeding into Extend our manufacturing history.
Fortunately, we maintain several years of manufacturing data; consequently, we
were able to loan an entire years worth of data into the modeling software.
Totally honest
Our initial computer modeling showed we still had
far to go. For one thing, it was quite evident that the data from the vendors
lacked sufficient credibility to enable us to create a stable model environment.
We were able to go back to the vendors and help
them better understand the limits of their performance metrics.
This discussion was one of the main benefits of
this process. We were able to engage in a totally honest discussion to define
what we needed. The vendors, in response, were able to pinpoint their
performance metrics, making simulation possible.
Armed with the new performance specifications, we
ran the simulation. Initial gating factors were solved, but new, unforeseen,
challenges began to emerge. Being aware of these challenges let us solve
performance issues before contracts were signed.
A side benefit: Since we had the ability through
SAP to look at real-time costs we were able to couple the simulation runs with
cost information to establish operational economic models that have proven
reliable.
The new mailroom was installed and has performed
to our expectations.
Looking ahead
We are working on examining our current product
mix to compare new press technology with our current infrastructure.
This takes us into new and somewhat uncharted
territory.
To do this, we are currently working with major
press vendors Heidelberg, MAN Roland and WIFAG. Our efforts are focused on
validating manufacturers specifications and seeing how new press capabilities
might support new businesses.
In the United States, most newspapers only buy
new press equipment because their current presslines are aging or obsolete.
Rarely would a newspaper anticipate that a new
press might impact its operating structure. Nor would a paper assume that less
equipment could produce more products.
Quite frankly, this is logical. Our industry and
its capital capabilities are appropriately defined as mature and as such,
they rarely offer opportunities for dramatic innovation.
Freedom from constraint
This is where simulation can open up your
thinking. Simulation lets you examine previously unexplored concepts. At the
same time, you can find out how much each step of the concept will cost.
This freedom from constraint is leading us toward
answers that previously would have been unthinkable.
When we put the information into the model it
will allow us to create realistic virtual-world press runs, complete with
planned stops and restarts, unplanned production interruptions and various
process flow concepts.
As we run the virtual press runs we can
simultaneously operate costing models that yield the operational economics of
the various iterations.
As the two models progress we are able to build a
very solid foundation for decision-making. One of the greatest values of this
approach is that in many cases constraints almost always turn out to be only
part of the answer.
This pushes your horizon back in thinking about
the problem. Bottom line: Managing expectations and making implementation happen
as predicted.
