Job 1 can be started right away, will require 2 hours to process and the customer wants it done by 12:30 pm. Job 2 can be started after 9:30 am, will require 1 hour to process, & the customer wants it done by 10:30 am. It is customary to set start time t=0 & express all other times with a suitable unit (t=0=8:30 & all else in hours) Comparison of schedules example 2: now there is a parking fee.
