The Channel Strategy Simulator

A public-facing version of the internal model for price, market capture, candidate site allocation, city potential, and operating cost. It is a directional pilot-economics tool, not a financial forecast.

Site profit

Πi=∑j∈Ji[g(p)Qij(1−e−βijnij)−Fij1nij>0−Mijnij]−(Slog⁡+yi)Ni1+αgNi\Pi_i=\sum_{j\in J_i}\left[g(p)Q_{ij}\left(1-e^{-\beta_{ij}n_{ij}}\right)-F_{ij}\mathbf{1}_{n_{ij}>0}-M_{ij}n_{ij}\right]-\frac{(S_{\log}+y_i)N_i}{1+\alpha_g N_i}

Site demand

Qij=wij[(Aia+Bib+Cic)⋅Si⋅ρ],∑jwij≤1Q_{ij}=w_{ij}\left[(A_i a+B_i b+C_i c)\cdot S_i\cdot \rho\right],\qquad \sum_j w_{ij}\le 1

Greedy allocation rule

Δπij(n)=Πi(…,nij+1,…)−Πi(…,nij,…),install if max⁡i,jΔπij>0\Delta\pi_{ij}(n)=\Pi_i(\ldots,n_{ij}+1,\ldots)-\Pi_i(\ldots,n_{ij},\ldots),\qquad \text{install if }\max_{i,j}\Delta\pi_{ij}>0

Profitability Phase Diagram

Monthly contribution across greedy site allocation. Curves continue after each city's N* so the forced-overdeployment decline remains visible until New York's N*. City labels sit at their own peaks.

Model Notes

Machines are allocated into synthetic high-demand micro-sites, not spread uniformly across a city.

Site-level demand saturates by tier, so each added machine must clear a positive marginal-profit threshold.

The model is most useful for deciding what must be validated in the first campus pilot before broader city expansion.
