ABSTRACT
Maintenance. is. an. important. element.of. the. engineering. equipment. life. cycle.. In. fact,.according.to.various.studies,.normally.much.more.money.is.spent.to.maintain. equipment. over. its. entire. lifespan. than. its. original. acquisition. cost.. For. example,. according.to.a.United.States.Air.Force.(USAF).study,.equipment.repair.and.maintenance.costs.are.approximately.10.times.greater.than.its.original.procurement.cost.1. Needless.to.say,.the.maintenance.of.medical.equipment.or.devices.is.as.important.as. their.design.and.development.
