Question 1
Four floral arranging jobs are to be carried out across three stations: A (Arrange), B (Bag), C (crop) shown. The station sequences and job times in minutes are shown below, along with the due dates for each job. Using an "earliest due date" job dispatching priority rule, which, if any, of the jobs in will be late? Tip: create a Gantt chart schedule before answering Questions 4 & 5.
a. Jobs 2 & 3
b. Jobs 3 & 4
c. Job 3
