• Network facility-location models
• Nodal-optimality property
• Extremal conditions also exist in planar location models

Spatial Location & Allocation
• Gaming• Generalized transportation
model – Includes regional input-outputs
• Equilibrium vs. Disequilibrium – Generalized multi-regional growth equilibria
• Entropy
–freq. with which an event occurs
• Entropy maximization
– to capture all possible patterns (information-minimization or spatial uncertainty principle)

Random or Poisson Field• Backshift operator, lag
operator, image-processing mask, & spatial location/allocationAll based on a weight matrix
• Homoscedasticity, stationarity, homogeneity If the correlation parameters are finite, the derived local averaging field become a continuous parameter Gaussian field.
• Ergodicity and isotropyA useful property & through proper local-averaging, such properties can often be obtained
