Risk Management (RBM)

Risk management.

Beginning in the 1970s, the world's leading industrial companies began to abandon the classic system of planned and preventive repairs (PPR) due to the significant economic costs of its use. The main purpose of PPR is to ensure the level of reliability of equipment not lower than specified. Achieving the goal is performed by replacing the equipment until its resource is exhausted. That is, most equipment has unused residual resources. In addition, up to 98% of equipment maintenance work during PPR did not need to be performed. As a result, a high level of equipment failure is achieved through high financial costs.

Maintenance optimization is an understanding of the application of risk principles to maintenance and the use of practices and systems needed to support decision making.

The modern approach to equipment maintenance is called RBM (Risk Based Maintenance) – a service that is based on minimizing the risk of failure.

The application of risk management principles is performed using a risk matrix that assesses the impact of the maintenance task on the following:

  • the probability of equipment failure.
  • consequences of equipment failure.

Maintenance is essentially treated as a risk control process.

The main techniques of RBM are:

  • reliability-oriented maintenance (RCM),
  • failure mode and effect analysis (FMEA)
  • error tree analysis (RCA)
  • event tree analysis (ETA)
  • failure characteristics analysis (FCA)
  • criticality analysis

The logic of RCM-analysis allows to determine the optimal strategy for equipment maintenance, taking into account the following factors:

  • impact on production indicators
  • impact on the environment
  • impact on security
  • the ability to detect and predict failure.

SmartEAM develops state-of-the-art software products for the implementation of reliability-oriented maintenance (RCM) maintenance techniques, RCA analysis.
