The cost of the system covers that for equipment, salaries and wages of doctors and
nurses, and other miscellaneous costs which include maintenance. The cost of host computers at the hospital is about 1,700,000 yen (US$14,166) which includes
installment fees, at the cost of 250,000 yen (US$2,083) per device. The total costs of
200 devices are about 37,600,000 yen (US$313,333). Development of software prior
to installment cost 4,000,000 yen (US$33,333), which is also considered part of the
initial costs. We assume that 10% of the value of equipment can be considered its
current value after six years of operation; therefore 90% of the value of equipment is
included in the costs, which amounts to 38,970,000 yen (US$324,750). This is paid
for with a one-time payment at the beginning.
