RoadmapAsset Strategy Differentiation & Optimization

Asset Breakdown Structure (ABS)Functional Decomposition of Asset by Process Steps and into Independent Systems

Goal & Benefit• Partition Facility into logical Asset Tree• Enables Fast Asset Criticality Ranking• Equipment inherits Meta Data that is defined at

desired level in Asset Tree (e.g. Maintainability, Deferment cost)

System Definition• Clear Function Definition• Independence (Risk/Criticality)• Isolation is Safe & Technically Feasible• Cluster Tasks (Work Order Scope)• Cost Reporting possible at each level in Asset Tree• Define each Sub-System as large as possible to

create efficiencies (Minimize Number of Systems)

Equipment

Maintainable Item

Failure Mode

Goal & Benefit• Group Equivalent Equipment Types into

Classes• Standardization, Consistency & Optimization• Fast EAM deployment

Asset Strategy Library – Part I• Equipment – Maintainable Item – Failure Mode• Maintainable Item (MI) is the smallest component/

part that is repaired or replaced in the Equipment• Failure Mode (FM) is one or more ways in which

each MI can fail• Standard way to create EBS is ISO 14224• Define Mean Time to Fail (MTTF) and Mean Time to

Repair (MTTR) per FM.• Define Failure Distribution (Weibull) per FM• Fixed vs Context data (Based on meta data: e.g.

Product Medium, MI material, Temperature, Load)• Equipment and MI Value & Age (Life Cycle Cost

Analysis – LCCA)

Risk Based Maintenance - RBMFunction, Failure Mode & Failure Effect

Asset Strategy OptimizationPreventive vs Corrective Strategies that mitigate Failures to an acceptable level

APM Predictive AnalyticsCondition Monitoring, Anomaly Detection & Failure Mode Prediction

Predictive APM = Event Based Asset StrategiesPredictive APM requires “Pit-Stop” approach to Execute Tasks within P-F Interval of the Alert

Predictive Asset Strategies trigger unforeseen EVENT BASED Work Orders.

Time & Usage based Strategies (“Classic”) schedule anticipated PLAN BASED Work Orders.

Event Based Tasks require Pit-Stop Approach for successful execution• Demands careful Preparation• Requires Agility and Discipline• High level of Execution Maturity in Processes &

Organization• Requires advanced Tools for Prioritization, Scheduling

& Tracking of Work Orders: Operationalize, EAM, Mobile, Control of Work, MES, Skelta)

Business CaseRealize Value with APM Prediction and Prescription


Objective

• Reduce the scope, workload and duration of Turnarounds.

Method

• Use Machine Learning (PRISM) to monitor sensor data, diagnose equipment

anomalies and predict failures. Postpone Tasks to next Turnaround.

Before: Sensor-Centric Approach


Model & Fault Diagnosis

• Group similar types of sensors into

one Model (e.g. not combine TEMP

and VIBR)

Anomaly Detection

• Only detection of Anomaly, no Failure

Prediction with Actions

Fault DiagnosisModel

After: Failure Mode Centric Approach


Fault Diagnosis:Rebuilt with Failure
