Alternative hierarchical location-allocation models are used to locate
two types of community-based health facilities in Davao City relative
to population locations. Accounting for factors such as politics
and resource availability, different optimization approaches were
implemented to locate a mix of health centers and nutrition posts
across the rural and urban areas of the city. The results were evaluated
based on operating costs, average travel distance and population
coverage. Computational results revealed that, by optimally locating
barangay health centers and health and nutrition posts, the current
level of public investment in the health delivery infrastructure can be
sufficient to cover a significant proportion of the population and at the
same time, reduce the travel distance to these facilities. Greater cost
savings could be generated with a network comprised of fewer facilities
since the overall operating costs are reduced. Significant policy insight
that can be derived from this study is that public investments are more
effective and efficient when community-based health facilities are
optimally located
