apmOptimizer

For Fleet and Asset

BQR’s apmOptimizer is an integrated solution for asset maintenance and logistics optimization, as well as for strategic decision making during asset design or overhaul.

apmOptimizer calculates the expected asset behavior based on a flexible model which accounts for operation profiles, failures, inspections, maintenance, spare parts, down time, and cost.

apmOptimizer’s optimization modules find the optimal maintenance and logistics policy that minimize the Life Cycle Cost (LCC) while maintaining a high asset availability.

Main modules

  • Life Cycle Cost Analysis
  • Level Of Repair Analysis (repair or replace)
  • Spare Parts Inventory optimization
  • Scheduled Maintenance Optimization
  • Predictive Maintenance (PdM) Optimization
  • Performance analysis
  • RCM and MSG-3 management

The following diagram presents a standard method for maintenance and logistics optimization

Benefits

  • Reduce spare part, maintenance and down-time cost by an average of 35%
  • Balance CAPEX and OPEX
  • Optimize for asset availability, No need to define equipment criticality

Highlights

  • Decision Support System for selecting the optimal PdM system: what is the expected ROI for sensors and IIoT in your asset?
  • Fast analytic calculations, used for high quality optimizations

Features

Analyses

  • Asset Reliability and Availability modelling
  • Spare parts optimization, accounting for shared stocks
  • Maintenance optimization including grouping of activities
  • Performance (production) modelling

Modelling supports

  • Evident, gradual, and hidden Failure modes
  • Failure distributions
  • Redundancies

User friendly

  • Part Number Library
  • Import data from Excel or other BQR modules
  • Fault Tree view
  • Reliability Block Diagram view
  • Failure mode effects view
  • Calculate repair or replace time and cost from description of maintenance tasks and resources, or input direct values
Informative tree view

Steps for conducting a typical analysis

Import (optional)

  • Import the block tree, components and failure modes from BQR’s FMECA using BQR’s Core Database
  • Alternately, data can be imported from CSV files

 

User Input

  • Define project data such as: Life-Cycle period and operation profiles
  • Define the reliability model, repair and replace policy for each block
  • Define logistic options for the asset including: spare stocks, OEMs, shops, and transportation routes
  • Define costs of inspections, maintenance actions, and downtime
  • Define resources required for each inspection and maintenance task (optional)

 

Analysis

  • The software validates the user data. If data is missing, user is notified
  • Software calculates the expected asset behavior and LCC. Additionally, identify key failure and cost drivers
  • Software optimizes spare parts quantities, maintenance and logistics policies in order to reduce LCC while keeping high asset availability
  • Calculate asset performance

 

Reports

  • Detailed reliability and availability parameters for each block
  • Detailed breakdown of LCC
  • Recommendations for: spare part quantities, inspections and preventive maintenance schedules
  • All reports can be saved as Excel, HTML or Word files

Definitions

Corrective Maintenance An action whose goal is to improve the state of equipment after the equipment failed.
Inspection An action in which the state of equipment is identified. If the state is found to be degraded, Preventive Maintenance action is scheduled.
Life Cycle Cost The cost of maintaining an asset over the asset life, including: inspections, corrective and preventive maintenance, spare parts procurement, transportation and storage, loss per hour of down time, and collateral damage due to failures.
Preventive Maintenance An action whose goal is to improve the state of equipment before the equipment failed.
