In this paper we describe a quantitative, linear programming (LP) base
d, resource allocation model designed for a state air pollution contro
l inspections program. The model is called the ''Inspection Optimizati
on Model'' (IOM) and was the result of a joint project between the Sta
tionary Source Compliance Division and Statistical Policy Branch of th
e United States Environmental Protection Agency (EPA). After several t
est runs and demonstrations that used real data, EPA decision makers a
greed that the model would be mutually beneficial to both the EPA and
state agency decision makers. Consequently, the model was accepted by
EPA for pilot implementation in a test state. The model's primary role
at the state level was seen as a planning tool for distributing resou
rces. It was envisioned that both the state and EPA would use the mode
l, secondarily, as an oversight evaluation mechanism to compare actual
performance and predicted inspection effectiveness.
