Asset Economic Risk Optimization (AERO)

Data-Driven Insights for Smarter Investments

UMS Group’s AERO (Asset Economic Risk Optimization) application helps companies to optimize their asset replacement plans by applying a risk-based approach to generate optimal multi-year replacement plans. It evaluates asset health, intervention costs, consequences of failure and other factors to determine the optimal time for replacement or other interventions of aging infrastructure.

AERO provides stakeholders with a ‘best practices’, repeatable, data-driven methodology. It enables improved, defensible capital spending decisions on asset replacement and refurbishment and facilitates transparent discussions with regulators and other key stakeholders. AERO delivers these insights by combining predictive analytics, optimization analyses, and data visualization.

Functions and Capabilities

Benefits Overview

Unlock the power of data for holistic asset management. Through diverse data sources and AERO’s analytics, craft optimized spending plans and manage long-term risk effectively. Expedite decision-making with deep-dive analyses, driving efficient asset replacement planning. Communicate transparently with automated outputs, supporting regulatory filings backed by persuasive data-driven arguments. Seamlessly integrate data sets with UMS Group’s expertise for successful implementation, drawing on their industry knowledge for comprehensive support at every stage.

Goals you want to achieve:

  • Repeatable, defensible process
  • Justify and prioritize spending
  • Consistency across assets and decisions, e.g., replacement, maintenance
  • Achieve buy-in and early gains via tried and true implementation process

Inputs that must be considered:

  • Health indexing and failure probability
  • Consequence cost (criticality)
  • Intervention options – what can I do to reduce risk?
Determines appropriateness of replacement / refurbishment intervention in lieu of maintenance / monitoring / “run-to-failure” strategies.
  • Assists in prioritizing replacement / refurbishment based on a calculated benefit-to-cost of replacement / refurbishment ration.
  • “Benefit” represents the costs that will be removed through replacement / refurbishment (includes projected corrective maintenance costs and monetized risk – by far the largest contributor).
Establishes “effective age” (integrating actual age of an asset with an assessment of its condition) of each asset and presents an age profile reflecting this added intelligence.
  • In instances where inspection and test results are available (e.g.; station transformers and breakers), an Asset Condition Assessment (ACA) can be converted into an Asset Health Index (AHI). Through use of an empirically or SME-driven hazard curve, AHI can be used to determine effective age, and by inference, probability of failure at a specific point in time.
  • In instances where assets cannot be routinely inspected or tested, an ACA can be determined by a blend of known information (e.g.; type of material for buried pipe and known soil condition, and vintage of and process used to install URD cable) and SME expertise.
  • Lacking either inspection and test results or additional intelligence regarding specific assets, the default position is that the actual and effective ages are synonymous.
Supports the Strategic Capital Investment Portfolio Optimization process.

Provides a risk-based approach in identifying asset replacement / refurbishment projects for consideration during the strategy-driven capital investment planning process.

Current Industry Status

The electric and gas utility industry is faced with many issues which are negatively impacting its ability to maintain reliable assets. To respond to these issues, utilities need to ensure they are spending their limited O&M and Capital dollars where they can provide the greatest impact.

This requires balancing the benefit of delaying costs as long as possible with the cost due to risk of failure as assets age and their condition degrades. AERO uses data such as asset condition, failures, and consequences to produce streams of risk, capital, and O&M costs to support decision-making on maintaining, repairing, and replacing assets.

The Challenge

At most utilities, the approach to identifying assets at end of life is a technical one where they replace or rehabilitate them when their condition is pooror their age reaches the “expected service life” for the asset type in question. The problem with this approach is that it does not consider risk in a quantitative way; it is subjective and qualitative, relying heavily on the opinions of technical experts.

The Solution

UMS Group’s AERO application harnesses data visualization and analysis as well as powerful integration technology to enable more effective decision making. It applies a risk-based approach to the replace vs. repair decision, and it supports replacement prioritization based on a cost/benefit analysis.

Optimal timing for individual asset replacement is established, considering the full range of costs of failure (e.g.; Safety, O&M, Capital Investment, Risks, Customers, and Environmental costs). By formulating asset class specific health indices, your utility can adjust actual age to effective age, identify common failure modes while defining consequences, and perform economic analysis of the expected consequence cost of failure vs. cost of intervention.
