Narenthorn database. Eight provinces are not included in the
database, representing 26.8% of the total number of emergency
responses. Extrapolating to whole Thailand gives a value of 2.2
billion Thai baht (¼ US $69 million) for response time and 1.1
billion Thai baht for operational time.
As an example, assume that an investment was made in a
new call-taking and dispatch system that could decrease the
response time and the operational time by 1 minute. Using the
results from this study, assuming a technology life of 20 years,
and a social interest rate of 6%, the present value of the benefits
of such an investment is between 12.8 and 25.6 billion Thai baht.
