Site selection · SDSS

A spatial decision support system, not a heat map.

Score a city with weighted criteria, forecast the shortlist with a calibrated Huff model, measure cannibalization and read the catchment — all in one scenario you can save and share.

01

MCDA suitability, your weights

Population density, income, daytime population, traffic, growth, competition, complementary businesses, rent and demand gap are min-max normalized across the city. Rent and competition are inverted, so lower is better. Weights from 0 to 10 combine them into a 0–100 score per hexagon.

  • Ranked top sites with minimum spacing
  • Per-criterion breakdown for every pick
  • Weights saved with the project
02

Huff forecasts with calibration

For a candidate location, the model computes each hexagon’s probability of choosing every store in the category, including an outside option. A calibration factor fitted to observed visits turns modeled demand into daily and annual visit forecasts.

  • Square footage and brand strength inputs
  • Market share of category demand
  • Forecast trade area as hexagons
03

Cannibalization, store by store

The same model is run before and after the opening. The difference at each existing store is the cannibalization — reported in daily visits and percent, with distance, so you can see what is net new.

  • Top impacted stores
  • Total visits transferred
  • Your stores vs. competitors
04

Catchments that speak your units

Rings in miles, kilometers or drive minutes, with demographics aggregated by the share of each hexagon inside the ring, plus segments and the business mix.

  • Area-weighted demographics
  • Lifestyle segment shares
  • Places by category inside each ring

Frequently asked

Are the formulas documented?

Yes. The methodology page publishes the Huff probability, calibration, cannibalization, normalization and aggregation formulas exactly as implemented.

How are drive-time rings computed?

Drive minutes are converted to a radius using each city’s average driving speed. It is a fast approximation, not a road-network isochrone, and the docs say so.

What counts as an analysis?

Each successful suitability, Huff, catchment or compare-sites run counts as one analysis toward the plan’s monthly limit.
