7. Tom’s Sailboard manufactures custom wind surfers in Seattle. The incoming orders follow different routes through the shop, but all orders must stop at each of the three work centers (WCs) in the plant. The following table contains information regarding the four jobs that arrive over five days and need to be scheduled at the company. It is currently November 10 and Tom works a seven-day week.

Assume that the material for all orders is ready for processing as soon as the orders arrive and that a first-come/first-served sequencing rule is used at all work centers. All three work centers are idle as work begins on orders B and G on November 10.

a. Construct a Gantt chart depicting the processing and idle times for the three work centers for these four jobs.

b. How many days does each job wait in queue for processing at work center 2?
