Abstract
Availability performance is an efficiency measure which
can be calculated for any item - from a piece of equpment
to a whole production line. Detailed avalablitity
performance analysis oa a production line requires a
model which takes into account the logical structure of
the system. As input data, mean times between failures
and mean times to repair or their corresponding
statistical distributions are required for each item. The
input data can be supplemented with infromation on the
duration of preventive maintenance events and the
intervals between.
Several systems to collect the availability data exist a
process plants, but often the data is recorded in such a
form that it is diffucult to use. The proposed recording
an dclassification system for the availability data
includes, for instance, failure cause and its
consequence. The objective of the availability
performance modelling and improved data management is to
offer the pulp and paper plants and the machninery
manufactures better tools to improve equipment
reliability and efficency of their production systems.
