The Core Problem

Which combination of projects creates the most value?

Every project in your backlog earned its place. It clears a threshold, addresses a risk, or improves performance. The challenge is that you can't execute them all. The question isn't which projects are worth doing; it's which combination delivers the most value without violating your constraints and disrupting operations.

Projects are evaluated individually, but value is realised collectively. Two projects that each look attractive on their own may conflict in practice, requiring a combined outage that drives up downtime and erodes returns. Others in the same area can be bundled into a single shutdown, reducing losses and amplifying overall value.

The problem is scale. Even a modest backlog generates thousands of possible project combinations, far too many to evaluate manually with any confidence.

The real question isn't "Is this a good project?" — it's "Is this the best portfolio we can build?"

PORTFOLIOf(x) uses mathematical algorithms to find the optimal combination of projects that delivers the greatest business value while respecting budget, shutdown, resource and production-loss constraints.

Our Difference

Production aware optimisation

PORTFOLIOf(x) models your production process to reveal the hidden cost of portfolio decisions: lost production. By quantifying downtime impacts and balancing them against value, budget, resource, and shutdown constraints, it identifies portfolios that maximise total business value, not just project scores.

What the model captures

Production Impact — production loss across the process flow
Utility constraints — how a power or water outage throttles every line it feeds
Buffer absorption — how tanks and stockpiles reduce effective downtime
Standby coverage — whether backup exists, and whether it's itself being maintained

How It Works

Four steps from project backlog to defensible portfolio

Score projects

Assess each project against your value metrics e.g., financial return, safety, ESG and operational continuity. Weight against your strategic priorities to produce a single, comparable priority score.

Model the plant

Build a flow model that captures how assets combine to deliver production revenue: what's critical, where standby exists, how buffers absorb downtime, how utility failures propagate.

Optimise the portfolio

Evaluate millions of project combinations to find the highest-value solution within budget, shutdown, resource and production-loss limits. Don't rank, search.

Explore trade-offs

Review value vs budget, value vs production loss, and portfolio sensitivity to assumptions. Flag marginal projects, identify robust ones. Compare results to reach your preferred solution.
