Work Center

A work center has five jobs assigned to it. They are labeled, in the order of their arrival in the shop, as jobs A, B, C, D, and E. The work center may work on only one job at a time and must complete any job it starts before starting another job. Job A has a processing time of 6 days and is due to the customer in 9 days. Job B has a processing time of 2 days and is due in 16 days. Job C has a processing time of 4 days and is due in 10 days. Job D has a processing time of 3 days and is due in 7 days. Job E has a processing time of 5 days and is due in 12 days. Using the earliest due date (EDD) priority rule, what will be the average lateness of these orders?
