Supposed you have calculated the machine fraction for a particular work area and determined a value of F. Consider parts a and b separately (meaning changes discussed in part a do not apply to part b). You must fully justify your answers below. a. If the uptime or availability of the equipment increases by a factor of 10% and the number of parts you have to make increases by 5% and the time per part increases by 2% what will happen to the new value of the machine fraction, F' ? F F' F - F' Not enough information to tell b. If the number of parts you have to make increases by 7% and the time per part decreases by 7% what will happen to the new value of the machine fraction, F' ? F F' F = F' Not enough information to tell
