Susie Davis owns Balloons Aloha and must fill Balloons with helium and assemble them into certain configurations today for six major parties. Her six customer jobs all need to use the same helium tank, (that is, the single processor), and she was wandering what might be the best way to sequence these jobs. Client (jab) number 5 is Balloons Aloha?s top costumer. Her assistant store manager, Lee Sailboat, wants to process them in sequential order, [1, 2, 3, 4, 5:, and 6]. Since the Balloons lose air quickly, the company waits until the day Of the parties to fill them and then the workload is hectic. Business is booming and growing about 15 percent per year in their new store location. The job processing times are as follows:

1. Compute the average flow time, lateness, and tardiness for this group of jobs using Mr. Sailboat?s sequential order of 1(first), 2, 3, 4, 5 and 6 (last).

2. In what order would the jobs be processed using the SPT rule? Compute the average flow time, lateness, and tardiness for this group of jobs?

3. Compare the answers in questions 1 and 2.

4. What are your short-term recommendations for this set of six jobs? Justify and explain.

5. What are your long-term recommendations with respect to sequencing jobs at Balloons Aloha? Justify and explain.
