Methodology v1.0
How the industrial-node scores work
No score without a method, and no method without its missing-data rule. Unknown inputs are treated as missing, never as zero.
Shared rules
- Score = weighted mean of evidenced components × 100, rounded to the nearest 5. Components without evidence are excluded from the mean and counted against completeness.
- If evidenced components carry less than 70% of the weight, the score reads Insufficient Data.
- Confidence is the lower of a completeness tier (≥90% high, ≥80% medium) and an evidence tier (share of weight resting on high- vs low-confidence inputs).
- Distances are great-circle (straight-line) between approximate coordinates, rounded to 5 km and banded; road distances appear only when a source states them.
- Every dossier separates Fact, Techadyant analysis, Techadyant score and Opportunity surface.
- Data is dated (“Data verified: Month Year”). Nothing here is real-time.
Industrial Connectivity Score (ICS) Computed
How well is this node physically connected to the national freight, gateway and logistics network?
| Component | Weight | Rule / input |
|---|---|---|
| Road | 20 | 1.0 expressway · 0.8 expressway on trial · 0.6 national highway · 0.3 state highway only |
| Rail | 20 | 1.0 DFC station ≤ 25 km · 0.6 mainline station with goods handling · 0.5 broad-gauge line, goods handling not documented · 0.3 new line approved |
| Seaport | 20 | straight-line to nearest registered gateway port: ≤150 km 1.0 · ≤300 0.7 · ≤500 0.4 · >500 0.15 |
| Airport (cargo) | 20 | straight-line to nearest operational international cargo airport: ≤50 km 1.0 · ≤100 0.7 · ≤200 0.4 · >200 0.15 |
| Logistics node | 10 | operational MMLP/ICD/MMLH ≤50 km 1.0 · under construction ≤50 km or operational ≤150 km 0.5 |
| Freight corridor | 10 | operational DFC ≤50 km 1.0 · ≤150 km 0.5 · evidenced >150 km 0.0 |
Supply Chain Connectivity Score (SCCS) Computed
How efficiently can the node’s critical inputs and outputs move?
| Component | Weight | Rule / input |
|---|---|---|
| Supplier proximity | 25 | mean over the profile’s critical input categories: operating supplier ≤300 km 1.0 · operating in-state, distance undocumented 0.5 · planned/MoU ≤300 km 0.25 · none documented 0 |
| Import-gateway access | 20 | ICS seaport and airport values weighted by the inbound mix (fab 50/50 · backend 40/60 · electronics assembly 50/50 sea/air) |
| Export-gateway access | 20 | ICS seaport and airport values weighted by the outbound mix (fab 30/70 · backend 10/90 · electronics assembly 40/60 sea/air) |
| Multimodal access | 15 | share of four modes in usable reach: road ≥0.6, rail ≥0.6, air ≥0.7, sea ≥0.7 (ICS values; an unknown mode counts as not in reach) |
| Freight infrastructure | 20 | the higher of the ICS freight-corridor and logistics-node values |
Connectivity Gap Index (CGI) Computed
How far does available infrastructure fall short of what the anchor industry needs? High = large gap (constraint and opportunity).
| Requirement | Fab weight | Backend (OSAT) weight | Electronics assembly weight |
|---|---|---|---|
| Air cargo (time-critical, high-value) | 20 | 30 | 25 |
| Power reliability | 20 | 20 | 15 |
| Industrial water | 20 | 10 | 5 |
| Seaport access (bulk chemicals, gases, equipment) | 15 | 15 | 25 |
| Specialised warehousing (bonded, ESD, climate-controlled) | 10 | 15 | 15 |
| Multimodal integration (rail–road–air) | 15 | 10 | 15 |
Each requirement is assessed met (0), partial (0.5), gap (1) or unknown (missing). High CGI means a large gap — a constraint and, often, an opportunity.
Industrial Opportunity Score (IOS) Defined — not yet computed
How much industrial opportunity is a change likely to open at this node?
| Component | Weight | Rule / input |
|---|---|---|
| Infrastructure investment trigger | 20 | sourced projects affecting the node |
| Demand growth | 15 | sourced anchor capacity ramp |
| Import dependency of inputs | 20 | Atlas grid status for the anchor ecosystem |
| Supplier gap | 15 | critical input categories with no supplier ≤ 300 km |
| Localisation feasibility | 10 | analyst rubric: capex, IP barrier, volume |
| Logistics improvement | 10 | ICS delta from projects completing ≤ 3 yrs |
| Policy support | 10 | sourced scheme coverage |
Why not computed yet: Supplier gap and localisation feasibility depend on the SCCS supplier mapping; demand ramp is only partly sourced.
Strategic Node Score (SNS) Defined — not yet computed
How important is this location to India’s industrial network?
| Component | Weight | Rule / input |
|---|---|---|
| Sector concentration | 20 | approved/operating units in strategic sectors |
| Strategic industry presence | 20 | ISM / defence / critical-mineral designations |
| Transport convergence | 15 | operational modes (from ICS) |
| Supply-chain centrality | 15 | degree / betweenness in the Atlas graph |
| Export relevance | 10 | sourced export share or designation |
| Infrastructure investment | 10 | sum of sourced project costs |
| National strategic designation | 10 | NICDP node, SIR, defence corridor, etc. |
Why not computed yet: Export relevance and graph centrality are not yet computed consistently across nodes; four-node rankings would be false precision.
Distance bands (ICS)
| Component | Bands (straight-line km → value) |
|---|---|
| port | ≤150 → 1 · ≤300 → 0.7 · ≤500 → 0.4 · >500 → 0.15 |
| airport | ≤50 → 1 · ≤100 → 0.7 · ≤200 → 0.4 · >200 → 0.15 |
| logistics | ≤50 → 1 · ≤150 → 0.5 · >150 → 0 |
| freight corridor | ≤50 → 1 · ≤150 → 0.5 · >150 → 0 |
Source registry — data governance
Programme and platform sources with their access terms, and what Techadyant does with each. We do not scrape, reproduce or redistribute PM GatiShakti, ULIP or any other restricted dataset.

| 76 firms ink non-disclosure agreement with government to use ULIP data | nda gated; API registered; download none | No licence published; redistribution not stated | Not used. ULIP access requires registration, a use-case review and an NDA (as reported); NDA-gated data is incompatible with public redistribution. |
| Cabinet approves setting up of Integrated Transport & Logistics Authority | unknown; API unknown; download unknown | No licence published; redistribution not stated | Institutional record only. No ITLA dataset exists publicly yet; the Atlas holds a schema placeholder (itla.json) for datasets the Cabinet text names. |
