Multi-criteria analysis of tailings storage alternatives

Decisions on tailings alternatives are not only technical — they are structured decision problems involving risk, weighting, sensitivity, regulation and long planning horizons.

Multi-criteria analysis of tailings storage alternatives — 6 formal steps

Decisions on tailings alternatives must survive regulators, review boards, and time itself. Data Riders structured a defensible multi-criteria analysis (MCA) flow for tailings storage alternatives, connecting risk, cost, environment, community and long-term planning.

Six steps of the MCA flow

  1. Baseline and projections — define current state and production horizons.
  2. Alternative identification and pre-screening — long-list and first filter.
  3. Alternative characterization — technical, environmental, social and financial attributes.
  4. Multi-criteria definition and indicators — criteria, weights and measurable indicators.
  5. Multi-criteria decision — scoring, ranking and sensitivity analysis.
  6. Documentation and validation — traceable rationale for internal and external review.
