PAMSEN is a decision-support tool for multi-year, budget-constrained cable maintenance planning. It ingests your GIS/asset registers and model outputs, estimates asset failure risk, and proposes transparent, auditable renewal portfolios (Repair/Replace/Do nothing) that balance costs, reliability indices (SAIFI/SAIDI/ASIDI), and the number of replaced cables.
Key features:
- Data preparation & validation: Reads cable attributes, costs, customers serviced, and geometries; standardizes schemas/CRS for repeatable runs.
- Risk modelling: Uses a Neural Weibull Proportional Hazards (NWPH) model—censoring/truncation aware—to derive per-cable failure rate.
- Optimization engine: Mixed-integer, multi-horizon planning to minimize outage cost under annual budgets over a horizon considering failure dynamics. Return a selected plan with full audit tables for repair or replacement of cables.
- Maps & KPIs: Interactive action maps (Replace/Repair/Replaced/Do nothing), failure probability and customers overlays, plus yearly counts, budget utilization, and CSV exports.
