Stochastic Simulation of Field Operations in Surveys

KEY WORDS:
ABSTRACT
Discrete-event simulation modeling has become the most commonly used tool for performance evaluation
of stochastic dynamic systems in science and engineering. The field operations of surveys can be
classified as one of these stochastic dynamic systems. This paper describes the simulation and modeling
of simplified field operations for NHIS (National Health Interview Survey). In particular, we apply the
simulation and modeling methodology to the field operations. We use the 2004 NHIS CHI (Contact History
Instrument) data for the input modeling of the simulation. The input modeling methods are also described
in this paper. From this study, we have shown that the simulation model can be used for optimizing the
field operations by setting the controllable parameters before a decision is made and implemented. The
cost savings might be enormous and would not be at the expense of the response rate.
