In
his book Lean Six Sigma, consultant Michael George said that as much as
50 percent of capital investment in new equipment is made to compensate for the
under-performance of existing equipment due to low Overall Equipment
Effectiveness (OEE). It no wonder. For too long, too many manufacturers took a
fail-and-fix approach to the maintenance of their plant assets.
More
recently, manufacturers
are embracing predictive maintenance philosophies to boost OEE,
a method for measuring how assets contribute to a
production rate, yield, and utilization. With
plant maintenance consuming up to 10 percent of all operational expenditures,
according to Gartner Inc., manufacturers need to squeeze more value and
longevity from plant assets. They also need to find ways to improve plant
maintenance to meet new regulatory and competitive pressures, such as
Sarbanes-Oxley or FDA.
To this
end, a new generation of Web-based technology is letting them do so by
automating and optimizing asset management plant wide. Asset management software
systems are enabling manufactures to proactively reduce unplanned downtime,
comply with regulatory requirements, and minimize wear of critical equipment, to
cite just a few benefits. Companies can gather data on current and future
condition of production assets so that they can make wiser capital investments,
while the staff makes better maintenance decisions. By automating and optimizing
how critical assets are purchased and maintained throughout their useful life,
manufacturers can reap significant costs savings, productivity enhancements and
competitive advantage.
Such a
system can track critical maintenance and service levels, readings and
event-based condition monitoring, provide historical records of maintenance
activities, provide regulatory documentation, and help with inventory
procurement. For example, manufacturers can coordinate preventative maintenance
during planned downtime to help maximize output. The system can also provide
intelligence and predictability for maintenance activities by maintaining
historical information and performance indicators for product assets. Asset
management systems combine business rules with maintenance best practices and
tightly integrate into plant-floor and back-office business applications. The
technology also enables inventory control and automated procurement, reducing
expensive manual purchasing processes.
Consider
Ocean Spray, the Massachusetts-based manufacturer of Cranberry food products.
Across its entire North American enterprise, Ocean Spray maintains nearly 24,000
production, facility and fleet assets, including fillers, blending systems,
conveyors, case packers, high-speed labeling equipment, HVAC units,
refrigeration systems and forklifts.
An
enterprise wide asset management and service system provides the company with
instant access to work order information (including detailed descriptions, parts
ordered, receipt due dates and labor and materials usage), which is linked
directly to purchase order, vendor, job plan, equipment and labor data.
The
systems provide a single source for all relevant maintenance information, whether users need
to monitor the progress of a corrective work order, view upcoming preventive
maintenance (PM) events by work location or check open purchase orders.
Providing quick and easy access to all information has improved the plants?
asset management procedures, streamlined the creation and filing of POs and made
work management processes significantly more efficient.
Having
met their basic maintenance goals, the Ocean Spray team improved the maintenance
philosophy, and set a goal to increase the amount of proactive maintenance.
Accomplishing this goal resulted in a decrease in the number of priority one and
two work orders. For example, streamlining proactive maintenance allowed the
company Henderson, Nev., plant to reduce emergency and reactive work orders
from 34 percent to 26 percent. The shift to improve proactive maintenance
ensures that Ocean Spray receives as few maintenance surprises as possible,
enabling it to avoid expensive downtime.
Uniting
all assets
While asset management in manufacturing is not new, the scope
and approach has changed. Manufacturing
assets include production equipment such as robotic systems, assembly lines,
in-house paint, tools, equipment, instrumentation and body shops. But in the new
world of asset management, they can also include facility assets such as office
buildings and assembly halls, IT equipment like laptops, mobile devices and
servers, and fleet or transportation assets such as trucks, fork lifts,
automobiles and repair vehicles. It can even include the dispatchers and service
providers that facilitate asset maintenance. In other words, any fixed, physical
or capital asset that has a direct or critical impact on achieving corporate
objectives.
New
Web-architected asset management systems are enabling manufacturers to
consolidate these once-fragmented, disconnected operating domains into a
centrally managed holistic system. The reason: plant assets are, in reality,
tightly inter-dependent and function as a single system; so it only makes sense
that they are managed as a unified enterprise. To keep manufacturing lines
flowing, every asset must be œcapable??always in proper condition to run when
needed, and replacement parts readily available.
Maintenance
departments need to master a set of core asset management competencies and put
in place the required predictive maintenance programs. Asset management systems
provide the framework to make the decisions on improvement programs, as well as
the right decisions based on corporate objectives. For instance, asset
management systems such as MRO Software Maximo Enterprise suite provide
methodologies through which companies can deploy individual techniques such as
Total Productive Maintenance (TPM) and Reliability Centered Maintenance (RCM) to
increase asset reliability; Just-in-time (JIT) or Vendor Managed Inventories
(VMI) to manage their parts inventories; or Activity Based Costing (ABC) or
Zero-Based Budgeting (ZBB) to improve and optimize asset-related costs.
For
example, Swedish car manufacturer, Volvo Cars, was able to automate some
maintenance methodologies using an enterprise asset management system to reduce
production line stoppages while shortening the length of those that do occur.
Volvo also wanted to drive down the big-budget maintenance costs of equipment
like paint shop robots and the plethora of complex production equipment at its
Torslanda factory in Gothenburg, Sweden. Specifically, managers wanted to know
where faults were likely to occur during the production of new models. A new car
should be rolling off the plant assembly line every one minute, 12 seconds. If
an unforeseen malfunction in a power tool, for example, stopped the flow, the
stoppage would result in lost production that cut deeply into the company
bottom line. The managers needed to determine, for example, if building a new
model in a slightly different way would cause unforeseen and costly production
equipment faults. With that information, they could take preventative action and
also figure out how to best use labor and materials to perform both preventative
maintenance and emergency repairs.
œVolvo
has adopted a strategy which is actively seeking out new ways to create value in
the company production stream by managing assets more effectively,?said the
plant general manager of maintenance. When a robot or computer, for example,
breaks down, Volvo asset management system quickly orchestrates the people,
equipment and materials needed to fix it based on location, availability and
priority. And because Volvo managers could see a map of the critical assets
along with their demand for materials, equipment and labor, they now make better
informed decisions to optimize the maintenance supply chain.
Asset
management systems also help reduce regulatory liabilities. Manufacturers face
increasing safety, environmental and operational reporting requirements from
Sarbanes-Oxley, FDA, EPA, ROHS, etc., all which swell operational costs and cut
into manufacturing margins. Well managed and maintained assets can significantly
reduce the risk of incurring highly damaging and costly environmental issues,
from pollution to hazardous leaks to dangerous working conditions. They can also
help meet a range of regulatory compliance requirements as in the Life Sciences
industry, such as the FDA Regulation 21 CFR Part 11, calibration standards,
and the associated validation procedures specific to FDA-regulated industries.
Occidental
Petroleum Corp, for example, needs to adhere to multitudes of safety and
regulatory requirements. Failure to comply can result in penalties totaling
millions of dollars. After evaluating several technologies to help them improve
regulatory compliance, Occidental selected an asset management system to
optimize and schedule maintenance and compliance activities. Occidental
currently uses MRO Software MAXIMO software in the Thums unit in Long Beach,
California and Oxy Permian in West Texas.
The
Texas One Call System (TOCS) is one of the many regulatory requirements in the
state of Texas that the asset management system helps Occidental meet. This
requirement involves notifying the state prior to excavation. The regulatory
agency researches the area in which Occidental plans to dig and verifies if it
can proceed with the project. If Occidental is set to dig, then the agency marks
the site and gives Occidental a permit number. The number that the agency
provides to Occidental is associated with a work order and job costs in the
system.
Occidental
safety and environment personnel also use the asset management system to manage
their inventory of chemicals, and identify hazardous materials with codes and
Material Safety Data Sheets (MSDS). Lockout/Tagout procedures are built into the
job plans, which also have the necessary permit information noted. For example,
to check hazardous gas levels, maintenance personnel need to obtain a confined
space entry permit. The requirement for this permit is clearly built into the
job plans, and the maintenance professionals immediately know that they must
obtain this permit before moving to the next step.
The
company Oxy Permian system comprises six databases, which include Central,
North, South, Odessa, Slaughter Gas Plant and Mallet CO2 Recovery Plant. These
databases encompass 19 properties. Equipment tracking, associating costs and
recognizing the failure of a piece of equipment as it moves throughout a unit,
plant and region is critical. The history and performance of assets also needs
to be recorded.
Getting
19 properties to agree on a set of business practices was not an easy task; the
implementation team had to accommodate the wide range of needs. Based on
information from these divisions, the team defined the format that the company
would use for all preventive maintenance routines. To enforce this change, all
field operations now use handheld devices that allow them to choose from a
variety of pre-configured electronic work orders.
e had
different sets of work flow procedures for the field, plant and production
operations, and MAXIMO helped streamline these business processes,?said a
senior executive at Occidental. standard method of completing jobs now allows
us to share best practices information company-wide while giving management the
information they need to cut costs out of our maintenance routines.?/SPAN>
Manufacturers
are increasingly turning to enterprise asset management technology to automate
their process efficiency, reduce maintenance, and enhance return on assets. With
as much as 40 percent of manufacturing revenues budgeted for maintenance, these
savings can significantly contribute to the bottom line. Manufacturers need to
tap the wealth of critical data that the technology provides so that no profits
are left on the factory floor.
