Maintenance Strategy
The Maintenance Strategy module provides
support for determining the optimal
maintenance strategy.
Your Benefits
■ Minimized failure risk/costs
■ Minimized damage and
associated cost, minimized
consequential cost
■ Significant increase in
maintenance efficiency
■ Reduction of administrative
effort and expenditure
for maintenance
■ Sound, transparent and
reproducible strategies
The Task
Competition in the energy market mandates
critical evaluation of costs and benefits.
Budgets keep getting smaller – especially
when it comes to plant maintenance. The
right strategy for the individual components
is required. But even experts have a hard time
answering the question of what is the right
maintenance strategy. There are numerous
parameters affecting the result. Especially
when it is no longer just maximum availability,
but availability at the right time that counts.
are stored in an information and knowledge
base. This information and knowledge base is
used for regular revision of the individual strategies. Other resources available to decision
makers are performance indicators, evaluations
and reports. Plant Management Maintenance
Strategy creates considerable saving potentials,
especially by reducing the number of measures
without any adverse impact on plant availability. It is available as a state-of-the art Web
application and also in a traditional Client/
Server configuration.
Maintenance is indispensable to ensure long plant life. When it
comes to answering the question as to which strategy is right
for which component, the Maintenance Strategy module
provides invaluable support.
Our Solution
The Maintenance Strategy module allows expert
definition and documentation of the optimal
maintenance strategy. A tree structure supports
you in making decisions subject to plant and
cost priorities that can be modified to match
your specific requirements. Work plans are the
basis for implementing the selected strategy.
All component failures, malfunctions, damage
and deficiencies are automatically registered.
Any conclusions and experiences in maintenance can be recorded as “findings”, which
Answers for energy.
Functional overview
Selection of relevant plant items
Depending on its type, a plant has
between 5,000 and far more than
100,000 plant items. Those determined
as directly relevant for safety, availability
and reliability can be marked and filtered.
Malfunctions and causes
All failures, malfunctions and damage
rele-vant for strategic analysis including
possi-ble causes are determined for each
plant item, recorded and described.
Determining the strategy
Taking into consideration numerous
other technical and economical criteria,
a concrete strategy can now be defined
and described. A decision tree that can
be configured according to the plant’s
specific requirements can be used for
determining the maintenance strategy
for a malfunction cause.
Documentation of decisions
Behind every decision node there is a
dialog implemented for documenting
the decisions made. It provides text
fields, check boxes, calculation fields
and graphical elements.
Work plans for implementing a strategy
The strategy describes the route to
achieving the target. If it is not implemented in concrete measures, the target
cannot be reached. Thus, work plans are
available for implementing the strategy.
They describe the work to be carried
out including the required human
and material resources, necessary safety
precautions and all rules and control data
for calculating due dates. Condition-based
maintenance requires reliable analog and
digital signal values.

Useful support for defining the strategy: The decision tree assists in determining the preventive or
condition-based measures that help avoid malfunction, failure or damage.
Execution of maintenance measures
The work is executed with the help
of work orders. For simple repetitive
inspection or maintenance measures
activity lists are sufficient.
Recording findings
Findings are the knowledge and experience gained during maintenance work.
It is possible to enter failure, malfunction
and damage codes and suggestions for
changes to plant, its operation or the
maintenance strategy.

Evaluation and Reporting System
Apart from knowledge about the
operation and wear behavior of a plant
item, knowing the failure, malfunction
and damage behavior of a plant item in
as much detail as possible is essential for
determining the maintenance strategy.
For this reason, the reporting system
allows damage statistics to be evaluated
at any time.
Regular review of maintenance
strategies
The defined strategies do not necessarily
apply for the whole service life of a component. To account for this fact, you can
use the information and knowledge database for regularly reviewing the strategy
and evaluating the effectiveness of maintenance.
