Minimum number of workstations d. Assign tasks to workstations using the longest operating time. (Leave no cells blank - be certain to enter "o" wherever required.) Task Idle Time Work Station 1 IV V e. What is the efficiency of your line balance? (Round your answer to 1 decimal place.) Efficiency 1. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operation only 11 hours per day in regular time. (Round your answers to the nearest whole number.) cycle time to seconds per unit. Another option is to work minutes overtime
