This paper reports the progress made in developing a regional simulation model. It is essentially a case study of a model- building process. The model is interactive and linked with employment, population, land use, and transportation components. The models have undergone considerable refinement, calibration, and elaboration during this period. In particular, emphasis has been placed on developing a housing model that not only forecasts total supply and demand for the region (i.e., a macrospatial model) and allocates these totals to subareas (i.e., a microspatial model) but also uses these microspatial data to generate successive housing forecasts at the macrolevel. The failure of earlier work to identify such micro-macro gaps and develop suitable linkages is one of the significant shortcomings of simulation modeling, and this paper discusses approaches that have been taken to develop such linkages. The response of the output variables to the inclusion of such links is compared with the output of the model without these links. Some observations about programming and debugging procedures are made. Output under various scenarios is presented, and a few general conclusions are drawn from this output. /Author/
