NEW • SEPTEMBER 2026

Latest research surfaced by Google Scholar.

These six papers were selected from nine new 2026 Scholar results because they most closely match SEA's maintenance, reliability and electrical-learning focus.

RCM + PM2026

RCM and Preventive Maintenance as a Hybrid Maintenance Model

Power-generation case study combining reliability-centered maintenance logic with preventive-maintenance methods.

SEA takeaway: fixed-interval PM should be justified by failure modes, consequences and asset criticality—not inherited by default.
Scheduling2026

Joint Scheduling of Jobs and Preventive Maintenance in a Flow Shop

Integrates production-job scheduling and PM planning instead of optimizing them independently.

SEA takeaway: the best PPM plan is one that can actually be released, staffed and executed without creating avoidable production conflict.
Electrical + ML2026

Failure-Risk Profiling and PM Prioritisation for 11 kV Feeders

Uses operational data and a Random Forest model to translate feeder failure risk into maintenance-priority indicators.

SEA takeaway: predictive models become useful when they lead to a transparent maintenance priority and their predictive limitations remain visible.
Generators2026

Preventive Maintenance Checklist Effectiveness on Generator Downtime

Compares generator downtime before and after implementation of a preventive-maintenance checklist.

SEA takeaway: measure checklist quality by defect detection, repeat failures and downtime improvement—not completion rate alone.
Reliability2026

Reliability-Based PM Planning for Pressure-Regulator Shut-Off Valve Components

Applies quantitative reliability analysis to maintenance-interval recommendations for critical valve components.

SEA takeaway: every maintenance interval should have an evidence trail: failure behavior, consequence, detectability and operating context.
Industrial Equipment2026

Preventive Maintenance Analysis for a Model 317 Tray Unloader

Reviews daily, weekly, monthly and annual preventive-maintenance activities for industrial material-handling equipment.

SEA takeaway: different frequencies should serve different inspection depths rather than repeating the same generic tasks.
RESEARCH-BACKED TOPICS

Engineering research worth following.

These links open live Google Scholar searches rather than copied paper content, helping the resource stay useful as new research is indexed.

Maintenance & ReliabilityResearch Digest

Predictive Maintenance: Moving from Time-Based PPM to Condition-Based Decisions

Predictive maintenance combines condition data, failure history and analytical models to identify deterioration before functional failure.

Practical takeawayStart with clean failure modes and trustworthy sensor data. A sophisticated model cannot compensate for poor measurements, inconsistent tagging or weak maintenance history.
Reliability EngineeringResearch Digest

Machinery Health Prognostics and Remaining Useful Life

RUL methods aim to estimate how long a component can continue operating before its degradation reaches an unacceptable condition.

Practical takeawayUse RUL as a decision-support estimate—not an absolute promise. Confidence ranges, changing duty conditions and failure-mode shifts matter.
Electrical MaintenanceResearch Digest

Industrial Motor Fault Diagnosis: Vibration, Current and Condition Signatures

Motor faults can often be detected through vibration, motor current signature analysis, temperature and other condition indicators.

Practical takeawayTrend data under comparable load and speed conditions. A single abnormal reading rarely tells the complete story.
HVAC & FacilitiesResearch Digest

HVAC Fault Detection & Diagnostics for AHUs and Chilled-Water Systems

HVAC FDD research focuses on recognizing abnormal operating patterns early enough to reduce comfort issues, energy waste and equipment stress.

Practical takeawayUseful FDD begins with reliable sensors, correct sequences of operation and clear baseline behavior for temperatures, pressures, valve positions and airflow.
PLC & AutomationResearch Digest

PLC-Based Automation: Fault Diagnosis Beyond the Program Logic

Industrial automation faults frequently involve the boundary between PLC logic and real field devices: sensors, actuators, networks, drives and power supplies.

Practical takeawayTroubleshoot in layers: process condition → field input → PLC logic → output command → field response. This prevents random component replacement.
Reliability & RCAResearch Digest

FMEA, RCA and Reliability-Centered Maintenance: Using the Right Tool

FMEA is proactive, RCA is event-driven and RCM helps choose maintenance strategies based on functions, consequences and failure behavior.

Practical takeawayDo not use one method as a substitute for all others. Define the engineering question first, then choose the method that fits the decision.
Solar & EnergyResearch Digest

PV + Battery Energy Management: Optimizing When to Store, Import and Export

Energy-management research evaluates how PV generation, battery state of charge, tariffs, forecasts and load profiles can be coordinated.

Practical takeawayOptimize against the actual tariff and operational objective. Maximizing self-consumption is not always the same as minimizing electricity cost.
Steam & UtilitiesResearch Digest

Industrial Steam Efficiency: Traps, Condensate, Pressure and Distribution Losses

Steam-system performance depends on more than boiler efficiency; distribution losses, failed traps, insulation, pressure control and condensate return all matter.

Practical takeawayQuantify the baseline before claiming savings. Trap-by-trap condition, operating hours, pressure and actual steam demand are essential inputs.
Drives & EnergyResearch Digest

VFD Energy Savings: Why Variable Torque Loads Matter

Variable-frequency drives can deliver large savings on suitable pump and fan applications when the process can operate efficiently at reduced speed.

Practical takeawayVerify the load profile, control objective, minimum speed and process constraints before estimating savings from affinity-law assumptions.
Industry 4.0Research Digest

Digital Maintenance: CMMS, Industrial IoT and Digital Twins

Connected maintenance systems can combine work-order history, live condition data and asset models to improve prioritization and reliability decisions.

Practical takeawayDigital tools create value only when asset hierarchy, failure coding, work-order quality and ownership are disciplined first.
Research-use note: Google Scholar is a discovery service, not a quality certification. SEA links to Scholar searches and does not copy or republish copyrighted research. Before applying any finding, check the full paper, publication venue, methodology, assumptions, data quality and relevance to your operating conditions.
