Land, construction and other cost estimates used to 
calculate project replacement cost, investor’s 
equity, mortgage, debt service charges, operating 
expenses and minimum economic rent. Economic 
theory employed. Flow diagrams, case examples and 
the model’s use for project, program and policy 
decisions presented. Programmed for time-sharing 
equipment 
San Francisco Community Renewal Program. Model 
of San Francisco Housing Market, C-65400, 
Cambridge, Arthur D. Little, Inc., January 1966 
Model matches households and housing supply to 
simulate residential development. Markov aging 
model, location characteristics, neighborhood 
classification, "fracts", space pressures and housing 
types employed. 35.000 computer instructions, 
15.000 data items, 2 1/2 hours IBM 7094 running 
time rquired. Will test policy when operable

Economic preference theory underlies a linear pro- 
gramming matrix minimizing aggregate investment 
costs subject to locators (residents, industries, etc. 
demand requirements; 30 zones, 400 variables, 60 
constraints, 20 minutes of IBM 7090 running time. 
Input requirements and the planners role in formu- 
lating, guiding and forecasting land development 
are discussed. Research model

Policy testing model developed and tested to project 
residential locations using job locations, commercial 
activity. Factor analysis used to derive multiple 
regression parameters. Input-output, linear pro- 
gramming submodels, 30 computer routines, 30 
minutes running time. Articulates structure of 
simulation models, information requirements, data 
collection and management
