Responsible for major research projects in the following areas: health care delivery systems, deployment of fire-fighting resources, police patrol allocation, and municipal refuse collection. This work has resulted in the development and imple-mentation of major planning tools for operating agencies of the New York City government, which in turn have led to significant operating changes in several agencies: Thousands of excess beds were eliminated or changed to other uses in HHC hospitals, patrol car assignments were changed throughout New York City, and the basic response policy of the Fire Department has been keyed to the potential seriousness of the received alarm. In addition, the number and location of fire engines was greatly changed in key regions of the City.
